It is been more than five years this video it's a really well explained and you are the only one explain the lateral dimensions of class D airspace thank you very much
Great video! I have a question on the Class D dimensions, in the AIM there is no reference for the radius dimensions of this airspace, however the AIM states class C is 5 NM in radius, should this radius be the same for class D or is it 5 SM as your video suggests?
Great question! You are correct that the Class C airspace has defined dimensions of 5 NM and 10 NM. Nowhere in the AIM or the FARs does it actually state the radius of class D. The closest you'll find there is the 4 NM and 2,500 feet AGL for airspeed (91.117). The only official written lateral limits for D you'll find is that each is tailored to suit the needs or to contain the instrument approaches for that airport. However, when I was the assistant chief CFI several years ago, we dealt with the FSDO often, and the unofficial answer was 5 Statute Miles for most because that is the area that the TAF is valid for. If you get out your plotter and actually measure the radius of many Class D airspace you'll find that they are about 4.4 NM which is 5 SM. I tried to convey on the video that each individual airspace needs to be checked for the actual dimensions, but the 5 Statue Mile rule was something handed down to us flight instructors from the FAA examiners through out the years. -HOWEVER, I believe the FAA Written knowledge tests still have a few questions that state it is only 4 Nautical Miles, but as you mentioned, there is no definite number given anywhere. I do have a feeling these questions will be taken out as they continue to update all the written exams. Glad you enjoyed the video! I am planning on adding more in the near future.

Fantastic video. Well broken down and explained. This was an immense help. Makes a complex system much more simple to understand.
Thank you! I'm glad it helped.
Precise, well presented, well explained 👌🏼
High quality vid. Thank u.
Thank you!!! Great video
You RUclips-faded! We newd more videosike this. Great learning tool.

@@PilotRight statute, not statue.
Reminds me of a Seinfeld episode :)
Thank you
Good job,
