Airspace Requirments Memory Aids
When I was in flight training I heard a lot of suggestions to help me remember the visibility and cloud clearance requirements for different airspace. I compiled these tips into one table when I was preparing for my FAA exam. Here it is to help others…enjoy! My CFI drew a nice visual representation of this as well, which I’ll try to recreate electronically and post eventually.
| Airspace Class | Nickname | Memory Aid | Visibility | Cloud Clearance |
| E & G above 10,000 msl | High Regular | 5-F111’s | 5 SM | 1,000 above 1,000 below 1 SM horizontal |
| C, D, E & G below 10,000 at night | Low Regular | 3-152’s | 3 SM | 1,000 above 500 below 2,000 horizontal |
| B | Big | 3 clear | 3 SM | Clear of clouds |
| G day below 10,000 msl, but above 1,200 agl | Go | 1-152 | 1 SM | 1,000 above 500 below 2,000 horizontal |
| G day below 1,200 | Low Go | 1 Clear | 1 SM | Clear of clouds |
Note - I make no warranties as to the correctness of this information in the future. It was correct when I took the test, it is always the student/pilot’s responsibility to look up the current and correct information from the FAR’s (FAR 91.155).

Dan: I happened upon your website a few days before I am going to take the written. I really liked your airspace memory aid. Thanks for posting it for others to use. It was quite clever.
