Welcome to our Terms and Definitions Feedback Form!

Just as with every other publisher of rapidly evolving, complex content, occasionally there are things that we can improve upon. Sometimes the reasons for this are technical and sometimes they're not. What makes our materials and system unique is that, thanks to this direct link to our editorial team which you are now using, we can rapidly consider and incorporate your feedback. We hope that you can appreciate that we have this system in place not because our stuff is shoddy, but, rather, because it is good.

We gladly and sincerely welcome constructive, considered, and, where possible, cross-referenced feedback on specific items of content using the form below.

  • This is not the place for technical or customer support requests! We'll be happy to hear from you on such issues via our Online Helpdesk. Please use this form only to provide feedback relating specifically to one very particular piece of content (such as a single term/definition) as your message here will go to our editorial team only, not our technical or customer support staff. You will not receive a timely response (and in fact might get none at all) if you submit such a message through this system instead of via our helpdesk.
  • Please make sure your app/program content is up to date before using this feature - A very high percentage of false reports we get via this system can be traced to the fact that the user does not have the latest version of the program content on his/her device. Please be 100% sure (especially if you are thinking about submitting a ticket about a "missing image") that before submitting a ticket here that you have used the in-app or in-program update utility for the program or app in question (often available via a 'get updates' or 'check for updates' link or button from the main menu). This will also help ensure that you are studying the latest and greatest material!

Here is the current term:  If below it different substantially compared to how it appears in your app/software, be sure to update your software/app's content prior to using this form.
Aircraft Approach Category
  • ICAO: The following ICAO table indicates the specified range of handling speeds (IAS in Knots) for each category of aircraft to perform the maneuvers specified. These speed ranges have been assumed for use in calculating airspace and obstacle clearance for each procedure.

    Aircraft CategoryVATRange of Speeds for Initial ApproachRange of Final Approach SpeedsMax Speeds for Visual Maneuvering (Circling)Max speeds for Missed Approach
    ALess Than 9190/150 (110*)70/100100100110
    B91/120120/180 (140*)85/130135130150
    • VAT - Speed at threshold based on 1.3 times stall speed in the landing configuration at maximum certificated landing mass
    • * Maximum speed for reversal and racetrack procedures
    • Category E contains only certain military aircraft and is not included on all approach charts.

  • USA: A grouping of aircraft based on a speed of Vref, if specified, or if Vref is not specified, 1.3 VS0 at the maximum certificated landing weight. Vref , VS0 , and the maximum certificated landing weight are those values as established for the aircraft by the certification authority of the country of registry. An aircraft shall fit in only one category. If it is necessary to maneuver at speeds in excess of the upper limit of a speed range for a category, the minimums for the next higher category should be used. For example, an aircraft which falls in Category A, but is circling to land at a speed in excess of 91 knots, should use the approach Category B minimums when circling to land. The categories are as follows:
    • CategoryA Speed less than 91 knots.
    • Category B Speed 91 knots or more but less than 121 knots.
    • Category C Speed 121 knots or more but less than 141 knots.
    • Category D Speed 141 knots or more but less than 166 knots.
    • Category E Speed 166 knots or more.

Please do not use this form to tell us that the definition you saw doesn't necessarily match the context where you saw it. We use an automated keyword-based system to match the tens of thousands of definitions in our glossaries with our material. Sometimes, when a term has more than one meaning or use or when an abbreviation might stand for more than one thing or resemble a 'normal' word, this results in a definition for a term being shown that doesn't necessarily match the context. Please do not report such issues here. Rather, please use your best judgment to evaluate whether such definitions apply to what you're reading. If the answer is 'no' but nevertheless you feel the term doen't have a good definition in our system but should, please go back and find the 'suggest a term' link in the app. Thanks!
We welcome your feedback.  Please carefully fill out the specifics below. If you wish to comment on more than one term/definition, please fill out and submit this form separately for each.
Please Identify Yourself.  It's important, so that we can get back to you with feedback or requests for clarification.
