Gleim Aviation Weather and Weather Services 6th Edition, 1st Printing Updates NOTE: Text that should be deleted from the outline is displayed as struck through with a red background. New text is shown in courier font with a green background. The FAA recently released Change 1 to AC 00-45G, Aviation Weather Services, which serves as a source document for Part III of the Gleim Aviation Weather and Weather Services book. The following update contains all the pertinent information contained in the new AC that you need to be aware of. There are some small changes and FAA corrections included that do not affect the Gleim test, therefore they have been excluded from this update. If you would like to access the complete AC, you can do so by clicking here. Study Unit 6 – Radar Imagery Page 266, Subunit 6.4, outline level 3.c.: The long range composite reflectivity product is no longer available. Figure 6-13 on this page has been removed and Figure 6-14 on page 267 has been renumbered as Figure 6-13. Outline level c. is amended as follows. c. The maximum range of the long-range composite reflectivity product (Figure 6-13 below) is 248 124 NM from the radar site. 1) The “blocky” appearance of this product is due to its lower spatial resolution as it has one-fourth the resolution of the base reflectivity product. 2) For a higher-resolution (1.1 x 1.1 NM grid) composite reflectivity image, users must select the shortrange view (Figure 6-14 below. The image is less “blocky” as compared to the long-range image. a) Maximum range is reduced to 124 NM from the radar location.
Pages 297 through 300, Study Unit 11: This study unit has been removed from the text because the Lifted Index Analysis Chart is no longer produced. Pages 341 through 350, Study Unit 17: A new study unit is being added to cover a new topic in AC 0045. The Graphical Airman’s Meteorological Advisory (G-AIRMET) is a new primary weather product designed to aid in pilot preflight weather planning. It augments the text-based AIRMET by providing pilots with weather snapshots displayed in short time intervals. You can access the new Study Unit 17 by clicking here. NOTE: Because Study Unit 11 was removed, this new study unit will become Study Unit 17 in the Gleim text. This study unit does not replace any content already in the Gleim book; it is completely new content. Copyright © 2011 Gleim Publications, Inc. and/or Gleim Internet, Inc. All rights reserved.

Page 2 of 2 Page 390, Study Unit 22, Subunit 22.3, Outline level 5: Alaska Area Forecasts (FAs) no longer contain SIGMET information. As such, SIGMET references under outline level 5 have been removed. 5.
Alaska Area Forecast Content a. The Alaskan FA zones contain sections on Clouds and Weather, Turbulence, and Icing and Freezing Levels. 1) The Clouds and Weather section includes a) SIGMETs for Thunderstorms and Volcanic Ash; b) AIRMETs for IFR ceiling and visibility, mountain obscuration, and strong surface winds; c) Bases and tops of significant cloud layers; d) Visibilities of 6 miles or less and restricting phenomena; e) Precipitation and thunderstorms; f) Surface winds of 20 kt. or greater; g) Outlook using categorical terms (i.e., VFR CIG, MVFR BR, IFR SN WND); and h) Mountain-pass conditions using categorical terms (for selected zones only). 2) The Turbulence section includes a) SIGMETs for Turbulence; b) AIRMETs for Turbulence and/or Low Level Wind Shear (LLWS); c) Forecast of significant turbulence not meeting SIGMET or AIRMET criteria or that is forecast for the period 6 to 12 hours after issuance; and d) If no significant turbulence is forecast, NIL SIG will be entered. 3) Icing section includes a) SIGMETs for Icing; b) AIRMETs for Icing and freezing precipitation; c) Forecast of significant icing not meeting SIGMET or AIRMET criteria or that is forecast for the period 6 to 12 hours after issuance; d) Freezing Level; and e) If no significant icing is forecast, NIL SIG will be entered followed by the freezing level.
Page 451, Study Unit 34: The Graphical Turbulence Guidance (GTG) product described in Study Unit 34 has been upgraded to “GTG-2,” essentially a second generation product. The changes are such that a revised version of Study Unit 34 is necessary. You can access the new Study Unit by clicking here.
