Since an aircraft operates in a three-dimensional atmosphere, the pilot needs special instruments to obtain the necessary flight information in order to conduct a safe flight. •T  he pitot-static instruments operate on the principle of pressure differential to provide speed, rate of climb or descent, and altitude. These instruments include airspeed indicator, altimeter, and vertical speed indicator. •T  he gyroscopic instruments use gyroscopic principles to provide the aircraft’s rate of turn, attitude (which displays the position of the aircraft in space), and heading (which displays the direction in which the aircraft is flying). These instruments include turn coordinator, attitude indicator, and heading indicator.

Can my pet travel with me? Yes. Many people choose to fly privately because it affords them the opportunity to bring their pets in the cabin. Some private jet operators allow pets in the cabin as long as they are restrained in accordance with FAA regulations for taxi, takeoff, and landing. If your pet is small or an anxious flier, it is advisable to keep the pet in a pet carrier for the duration of the flight. Dogs not in a carrier must occupy their own seat and be secured with a seat belt or special dog harness during taxi, takeoff, and landing.

BEFORE DEPARTURE

Boarding a private jet is a very different experience from boarding a commercial aircraft. Rather than waiting in line for your seat row to be called and then walking down a jet bridge and waiting for other passengers to be seated before you can get to your seat, boarding a private jet is a comfortable and pleasurable experience. Generally, one of the pilots greets the passenger(s) in the passenger lounge of the Fixed Base Operator (FBO), verifies their identification, and informs them that the aircraft is ready for boarding. Then, the pilot takes the luggage and loads it into the baggage compartment of the aircraft while the passengers walk up the stairs and into the aircraft. Some private jets have baggage compartments that are accessible in flight should the need arise. Once the passengers are onboard, the flight crew gives a safety overview and then the aircraft begins to taxi to the runway. For many people, this sequence of events is commonplace, but there are many extremely intricate details that must be completed for an aircraft to depart. What do the pilots do immediately before a flight? Before the aircraft departs, the pilots are required to do a preflight check to make sure the aircraft is in sound working condition. The pilots follow a checklist that includes close inspection of the aircraft systems and the main components of the aircraft. Only after the checklist is completed and the flight crew is satisfied that all systems are in proper working condition is the flight cleared to depart.

BEFORE DEPARTURE

Do all airports have control towers? You may be surprised to learn that the large majority of airports in the United States do not have control towers. Generally, only large airports frequented by heavy commercial airline traffic and the busier general aviation airports have control towers, and, in many cases, these operate for only a portion of the day. Many of the airports that are frequented by private jets are much less busy than the airports commercial airlines use and, therefore, do not require a control tower. •C  ontrolled airports have an operating control tower. All aircraft in the vicinity and on the ground at controlled airports must follow instructions provided by the Air Traffic Controller. •U  ncontrolled airports require the pilots to selfannounce their intentions to other pilots in the airport vicinity using a radio. The pilots are also responsible for determining the active runway and how to enter and exit the traffic pattern by obeying established FAA regulations. How many runways do airports have? Generally, the busier the airport, the more runways it will have. Since aircraft are affected by winds during takeoff and landing, runways are usually built in the direction of the prevailing winds. Some airports have multiple runways aligned in different directions to best adapt to shifts in wind. What are airport identifiers? Most airports have both a three- and four-letter identifier which is a unique code used to identify each airport. Airlines typically use the three letter codes while most general aviation operators use the four letter codes. For airports in the United States, the four letter code generally consists of a “K” before the three letter code. For example, the three-letter identifier for Teterboro Airport is TEB and its four-letter identifier is KTEB.

BEFORE DEPARTURE

How are runways named? Runways have a two-number identifier on each end. These numbers are derived from the runway’s direction in degrees relative to magnetic north. For example, if the runway identifier is 09, it means that the aircraft will take off or land at a heading of 90 degrees or due east. If the runway identifier is 27, it means the aircraft will take off or land at a heading of 270 degrees or due west. The runway identifiers represent the direction in which the aircraft will be heading while taking off on that runway. For this reason, each strip of pavement is actually two runways because each end of the runway has a different name. Why do we sometimes taxi onto the runway and not move for a while? Sometimes an aircraft is instructed by an Air Traffic Controller to taxi into position and hold. This usually happens when the airport is experiencing a high level of traffic. For example, an aircraft may have just landed and may still be on the runway from which your aircraft will depart, or another aircraft may have just departed ahead of yours. Air Traffic Controllers need to keep a safe distance between all aircraft to minimize the effect of wake turbulence generated by other aircraft. Wake turbulence (also called wingtip vortices) is created when an aircraft is generating lift and can be hazardous to other aircraft flying on the same path and in close proximity.

All aircraft have certain limits to the weight of baggage that can be safely carried onboard.

FLIGHT BASICS

Flying is so commonplace these days that it is amazing to think that just over 100 years ago, flight in an airplane was simply a dream. Today, for many, flying is a necessity. A series of events must occur for an aircraft to fly safely. This section discusses the basic components of an aircraft and the nuances of flight. What are the main components of an aircraft? There are five main components that make up an aircraft: • The fuselage is the main body of the aircraft. • The empennage is the tail of the aircraft. It consists of two flight control surfaces: the elevator and the rudder. The elevator pitches or steers up and down, and the rudder yaws or steers from right to left. • The wings are the primary lifting surfaces for the aircraft. The airflow over the wing surface generates the vast majority of lifting force necessary for flight. • The powerplant or engine generates the power or thrust for the aircraft. Private jets generally have two engines. • The landing gear allows the aircraft to take off, land, and taxi and also provides shock absorbers to enable smooth landing and takeoff. The newest business jets usually have a type of landing gear known as “trailing link” which allows for smooth landing and taxiing.

FLIGHT BASICS

How does an aircraft fly? Flight is made possible by a concept known as pressure differential. Aircraft wings are designed to create a pressure differential between air above and air below the wing. Due to the shape of the wing (known as an airfoil), air flows faster above the wing and slower below the wing, creating a difference in pressure known as Bernoulli’s Principle. Bernoulli’s Principle states that, as a fluid travels faster (air is technically a fluid), its pressure drops. The lower pressure above the wing and consequent higher pressure below the wing allow an aircraft weighing thousands of pounds to rise like a graceful bird.

FLIGHT BASICS

What do aviation terms such as lift and drag really mean? For an aircraft to fly straight and level, four basic aerodynamic forces must be in equilibrium: lift, gravity, thrust, and drag. Lift is simply the force generated by airflow over the wings that acts opposite of gravity which is the force constantly pulling all objects toward the center of the earth. Drag is a negative force which acts against the thrust generated by the aircraft’s engines. Drag can be thought of as the resistance of the air against the forward motion of the aircraft. All portions of the aircraft create drag; it is an unavoidable trait of any object moving through air. When an aircraft is flying straight and level, the opposing forces balance each other; lift equals gravity and thrust equals drag. However, the aircraft uses imbalances between these forces to accelerate, climb, and descend.

FLIGHT BASICS

How does a jet engine work? There are four basic steps that explain how a jet engine works: Step 1: Air is drawn into the engine through a large fan at the front of the engine. Step 2: Behind the initial fan is a series of smaller rotating blades. These rotating blades compress the air and force it into the combustion chamber. Step 3: Once the air is compressed and enters the chamber, the air and jet fuel mix together and are ignited. The burning gases rapidly expand and are forced out the rear of the engine, producing “thrust.” The thrust pushes the aircraft forward. Step 4: As the exhaust gas exits, it passes through the turbine which spins a drive shaft to provide the rotational motion to the compressor, which in turn draws in more air and the entire sequence is repeated. In addition to feeding air to the compressor, the large fan at the front of the engine feeds air through bypass ducts around the compressor to join the exhaust jetstream in the tailcone. This bypass feature is what distinguishes a turbofan from a turbojet and it allows the turbofan to be much more fuel efficient and quiet.

FLIGHT BASICS

What are all those moving parts on the wing? The next time you are on an airplane, if you are seated over or slightly behind the wings, you will be able to watch the different parts of the wings work especially during takeoff and landing. The main parts of the wings include flaps, slats, spoilers, and ailerons. • F  laps allow the pilot to change the shape of the wing. Flaps can be extended to increase the wing surface area, creating additional lift. The more curved the wing is and the more surface area it has, the more lift it will create. Flaps are most often used during landing and takeoff so the aircraft can fly at a slower speed during an approach or help generate lift during a departure. •S  lats are located on the front of the wing and are designed to optimize airflow over the upper surfaces of the wings. They help aircraft fly more slowly during critical phases of flight, allowing the aircraft to takeoff from and land on shorter runways. Some aircraft do not have this component. •S  poilers, as the name implies, spoil lift. These devices are attached to the top of the wing and block the airflow on the upper surface of the wing, thus destroying the lifting tendency. Spoilers are used to control sink rate during descent and are also sometimes used for roll control. •A  ilerons are movable portions of the wing used for banking and turning. The ailerons are located on the outer section of the wings, and ailerons on both wings work together to turn or roll the aircraft. When an aileron on one side of the aircraft moves down, the aileron on the opposite side of the aircraft moves up. The wing that has the aileron down will experience more lift than the other wing and will rise. This motion rolls the aircraft into a turn.

FLIGHT BASICS

Why does an aircraft need so many different parts? Since aircraft operate in three dimensional space while in the air, they need several specialized systems to maneuver. The ailerons, rudder, and elevator allow aircraft to move and turn through the air. Ailerons allow the aircraft to roll from side to side. The rudder allows the aircraft to yaw, or turn from left to right. Finally, the elevator allows the aircraft to pitch the nose up or down. These three systems work together to allow the aircraft to ascend, descend, and turn in order to reach its destination.

AVIATION WEATHER

There are many types of weather that may impact your flight. A general understanding of these phenomena and how they affect aircraft operations may help your travel plans run smoothly and increase your comfort in flight. Thunderstorms can be hazardous to aircraft due to high winds, hail, and their generally unpredictable nature. Pilots, Aircraft Dispatchers, and Air Traffic Controllers put a lot of time and effort into trying to avoid storms, which can lead to air traffic delays. When multiple storms develop in a region, the storms block local air routes. Air Traffic Control centers must then begin to delay aircraft trying to fly through the affected areas. These delays have the greatest affect on high traffic areas such as New York and Chicago. Additionally, windshear, a sudden and unpredictable change in wind direction and/or velocity, may be caused by thunderstorms. Since it can cause a sudden loss of altitude, windshear is most dangerous to aircraft during the critical phases of flight (including takeoff and landing) and when the aircraft is flying slowly and low to the ground. Tropical weather in the Atlantic Ocean begins in early June and peaks in the fall. Such weather has the potential to greatly impact the accessibility of affected areas. To ensure the safety of passengers, operators may temporarily suspend operations in areas where tropical storms and hurricanes are forecast to make landfall. Fog causes low cloud base and reduced visibility that can limit flight operations due to the more stringent operational requirements (instrument flight rules) for operating in these conditions. The morning hours are affected most often, but fog often lasts well into the afternoon. Some of the popular airports most affected by fog include those located in Nantucket, Martha’s Vineyard, and San Francisco.

Do high altitude/mountain airports cause performance problems for aircraft? There are several factors that affect the runway performance of an aircraft. Among these factors are airport elevation, temperature, weight of the aircraft, winds, and runway condition (dry, wet, icy, etc.). As air increases in temperature, its density decreases. This is particularly problematic for aircraft departing from high elevation airports because the air is already less dense at higher elevations. The less dense the air is, the more runway length aircraft require to take off. This is because the aircraft’s engines are less efficient and the wings generate less lift when the aircraft is operating in less dense air. Often, this “hot and high” scenario may lead to an aircraft requiring more runway length to take off than is available at a particular airport. If this is the case, weight must be removed from the aircraft to safely take off on the available runway length. Reducing weight can be accomplished three ways: removing passengers, removing luggage, and/or removing fuel. If fuel is removed, there may not be enough fuel remaining onboard to reach your final destination nonstop, making a fuel stop necessary.

Can the weight of my luggage impact the flight? Weight can have a dramatic effect on aircraft performance. Each aircraft has a specific weight limit (maximum takeoff weight) which that cannot be exceeded. If the combined weight of passengers and luggage is particularly heavy for a certain flight, the pilots and aircraft dispatcher may determine that off-loading fuel is required to keep the aircraft under the maximum takeoff weight. This could lead to additional refueling stops. Alternatively, some baggage may be removed and shipped separately to reduce weight. In addition, weight has a direct impact on the aircraft’s takeoff and landing distance. In general, the heavier the aircraft is, the more runway length it requires for takeoff and landing. Depending on other environmental factors such as temperature, winds, and runway condition, additional weight could lead to an aircraft not being able to use a particular airport.

TAKEOFF AND CLIMB

Why do some aircraft need more runway length to take off than others? There are several factors that determine the runway length needed for an aircraft to take off, but the most important are weight, wing design, and engine thrust. Generally speaking, the heavier an aircraft is, the more runway length it requires to take off. The effect of weight can be offset somewhat by wing design and engine thrust. If the wing of an aircraft is relatively straight rather than swept-back, this allows the aircraft to take off at lower speeds and therefore requires less runway distance. In addition, more engine thrust allows the aircraft to accelerate faster and take off in less distance. The straight wing design and higher-thrust engines are helpful for takeoff performance, but they can have different effects in other phases of flight. For this reason, aeronautical engineers try to find the best possible balance of all components when designing a new aircraft.

TAKEOFF AND CLIMB

Right after the aircraft takes off, why do I hear a knocking noise and feel a sinking sensation? The knocking noise you hear is actually the landing gear retracting up into the aircraft. Later, you may also hear the flaps retracting back into the wing. The sinking sensation is caused when the pilot reduces the thrust on the engines. The engine power must be reduced during the initial climb because the engines cannot run at takeoff power for more than a few minutes. When the power is reduced, the aircraft feels as if it is sinking or slowing down dramatically. Should I be concerned about turbulence? Simply put, turbulence is air in motion that interacts with the aircraft. All aircraft are built with turbulence in mind, and the wings of the aircraft are made to be flexible to handle these forces. Due to the high altitudes at which they fly, private jets are usually able to avoid turbulence and provide a smoother ride. However, turbulence is often unavoidable during climb and descent. While it may be a nuisance at times, turbulence is an expected part of most flights. Aircraft are designed to withstand it, and pilots are trained to handle it. In case of unexpected turbulence, passengers should wear their seatbelts when not moving around the cabin.

CRUISE

Cruise is the portion of the flight spent flying level and not climbing or descending. Cruise is usually the longest portion of the flight when most passengers settle in to enjoy the entertainment amenities and catering, conduct business, or simply get some much needed rest. How high do private jets fly? Private jets typically cruise between the altitudes of 37,000 feet and 45,000 feet, which is above most airline traffic and adverse weather. Cruising at these high altitudes is advantageous because the skies are less crowded, and there is generally less turbulence. How fast do private jets fly? Most private jets cruise somewhere between 480 miles per hour and 560 miles per hour. The speed is dependent on several factors such as cruising altitude, traffic, and air traffic control restrictions. One of the fastest private jets, the Cessna Citation X, cruises at a maximum speed of 590 miles per hour. Most commercial airliners cruise around 500 miles per hour. What does “Mach” mean? The term “Mach” is named after the Austrian physicist Ernst Mach. Generally, Mach is used to refer to the ratio of actual speed to the speed of sound. For instance, if an aircraft is traveling at half of the speed of sound, we would say it is traveling at Mach 0.5, and an aircraft traveling at twice the speed of sound would be traveling at Mach 2. An interesting fact relating to the Mach number is that the speed of sound actually varies depending on the temperature of the air. As you probably know, air temperature decreases as altitude increases, so an aircraft flying at Mach 0.7 at 25,000 feet would actually be flying faster than an aircraft flying at Mach 0.7 at 41,000 feet.

Considering an east-west city pair, the total flight time is generally longer on the east-to-west leg than on the west-to-east leg. An aircraft may be capable of flying west to east nonstop for a particular city pair due to the tailwind but may require a fuel stop from east to west due to the corresponding headwind. Are private jets able to fly across oceans? Yes. In fact, there are many private jets capable of long-range transoceanic flights. Not all aircraft, however, are able to fly for long distances over water. Although an aircraft may have the capability to fly from one point to another over a large body of water, safety regulations may prohibit such a flight due to the aircraft’s inability to return safely to land should an emergency occur.

aircraft may operate: • Visual Flight Rules (VFR) require certain minimum weather conditions (visibility, which is the distance that can be seen horizontally, and ceiling, which is the altitude of the lowest cloud layer) be met in order to conduct flight operations. Depending on the airport environment in which the aircraft is operating, the visibility and ceiling requirements will vary. • Instrument Flight Rules (IFR) provide guidance for pilots to fly not only in visual conditions but also through clouds, rain, or other atmospheric conditions. These conditions are referred to as Instrument Meteorological Conditions (IMC). IMC describes a condition where the pilots do not have visual cues outside of the aircraft. The pilots use navigational aids and instruments in the flight deck to execute the flight safely. These rules must

be followed when weather is below VFR minimums or anytime when flying above 18,000 feet.

CRUISE

What types of flight instruments are used to navigate in IMC? To navigate in instrument airspace and/or under Instrument Meteorological Conditions (IMC), pilots use enroute charts which provide the locations of navigational aids and flight routes. There are numerous types of navigational aids positioned throughout the world which help guide pilots to their destinations, usually by using a radio frequency. The enroute charts are basically highway maps of the sky that allow the pilots to fly from point A to point B using navigational instruments. It is possible for pilots to navigate with precision to almost any point desired due to advances in aircraft navigational radio receivers, the development of aeronautical charts which show the exact location of ground transmitting stations and their frequencies, and refined flight deck instrumentation. In addition, many modern aircraft use global positioning satellite systems to help them navigate with precision.

conditions, traffic, or runway unavailability. What are fuel reserves? As an added safety measure, aircraft carry fuel in addition to the fuel required for each specific flight. This fuel is known as the fuel reserve and is required by FAA regulations. Before a flight, the pilot and dispatcher calculate the fuel required for the flight and then add the reserve fuel to the flight fuel. The fuel reserve is always carried and is meant to be used only in an emergency. What is an alternate airport? If the weather is forecasted to be Instrument Meteorological Condition (IMC) at a destination airport, the pilot and aircraft dispatcher are required to plan for an alternate airport which will have better weather than the instrument approach minimums. This is one reason why aircraft carry additional fuel onboard in case landing at the destination airport is not possible due to weather conditions.

DESCENT

What is a slot? A slot is a reservation to arrive at or depart from a specific airport at a specific time. The FAA administers slots for safety reasons. They are implemented to control the rate of arrivals and/or departures when the airport’s demand exceeds its capacity. Which airports require slots? Some airports use slot reservations year-round while others use them during special events and peak travel times based on anticipated traffic and/or weather. During high demand periods including holidays and weekends around school vacations, obtaining slots can be challenging. Most people want to land during the same narrow windows of time, whether flying privately or commercially. How do you obtain a slot? Slots are assigned by the FAA through a random lottery process. Commercial airlines receive their slots first, and then the remaining slots are put into a “lottery” for all of general aviation. Those slots become available exactly 72 hours prior to the requested arrival time. Since all general aviation companies and private parties are vying for the same slots at the same time, the slots are usually taken within seconds of being released. Slots are not confirmed until 24 hours prior to the day of travel.

LANDING

Landing is one of the most exciting phases of flight. Many of the same events that take place during takeoff also occur during landing but in the reverse order. How do aircraft land in adverse weather conditions? In adverse weather conditions, aircraft must fly under an instrument flight plan. There are several different types of instrument approaches, and not all types are available at all airports. Some of the approaches are more precise than others and, therefore, can be flown under lower weather conditions (lower ceiling and visibility). By simply using the procedures written in the approach charts and reading the flight instruments, the pilots are able to fly very close to the runway. If the pilot is still not able to see the runway after flying the procedure, they follow a missed approach procedure that allows the aircraft to climb safely out of the airport and avoid any potential obstacle while exiting. What does it mean when a runway has a displaced threshold? A displaced threshold occurs when a portion of the runway is not suitable for landing but can be used for taxi, takeoff, or landing rollout. This situation generally occurs when there is some sort of obstruction (trees, buildings, etc.) near the end of the runway. This may affect the aircraft’s ability to operate at an airport since the entire runway length is not available for landing. How does weather affect an aircraft’s ability to land? Weather can play a dramatic role in the operation of an aircraft. If fog, snow, or very heavy rains are occurring at the time of arrival or departure, the aircraft may not be able to operate. Even if the aircraft is able to operate, landing on or taking off from a runway covered with water, snow, slush, or ice will cause the aircraft to use more runway length than would be needed on a dry runway due to the reduced friction between the aircraft tires and runway.

LANDING

What happens if a runway has a slope? Many runways are not completely level, which can affect takeoff and landing performance. When a runway has an up slope or down slope, it is said to have a runway gradient. Upslope runways provide a retarding force which impedes acceleration and results in a longer takeoff distance. Landing uphill actually helps as it usually results in shorter landing distances. Downhill operations have a reverse effect. What is the Destination Airport Analysis Program (DAAP)? FAA regulations state that all Part 91(k) and Part 135 (the regulations under which many private aircraft operate) flights must be able to land within 60% of the available runway length on any given runway. DAAP allows approved operators to increase the landing requirement to 80% of the available runway, as long as all items on a 22-point “day of flight” safety checklist can be accomplished for the particular flight. Using DAAP allows operators to access many of the smaller airports frequented by private aircraft and ensures that they are safe in doing so. Each operator must have its DAAP approved by the FAA prior to use. What is that loud noise I hear just after the aircraft lands on the runway? The noise you hear is created by a system called a thrust reverser. The thrust reverser aids in stopping the aircraft by directing the exhaust flow of the engines in the forward direction. The forward flow of air creates a loud sound which is audible just after landing.
