I’ve always learned C-152 and F-111. The C being third letter of the alphabet stands for 3 miles visibility. The number one standing for 1000 feet above, the five is for 500 feet below, and the two is 2000 foot horizontally. That’s basic cloud clearance F-111 is for above 10,000 feet MSL that is F is 5 miles visibility. You guessed it, 1000 above, 1000 below, and 1 mile horizontally.
ARDVARK! Ive always used both. Besides that, the airspace triangle helps a lot for minimums in different airspaces and at different altitudes and times.
I remember it like thus... 3-152 train in D, C and E airspace. How I remember the clouds is by drawing a "reverse" check mark; 1k feet above, 500 below and 2k horizontal. Class B is busy with airliners and there are 3 "cocky" pilots (coc = clear of clouds, lol). The F-111 flies above 10k feet so that's the five SM vis with 1k feet above and below and 1 SM horizontal. For class G I remember that only 1 cocky pilot flies that low during the day and at night he wises up and flies like the rest of the training aircraft, so thus 3-152. lol.
I am a student going for my ppl and have been struggling with airspace clearances, and none of the diagrams I’ve seen seemed to help. The second I read this comment, it all clicked. Thank you!
I've always liked starting with night minimum b/c C, D, E, and G are all the same below 10,000 feet at night. Then, G is the only one that changes during the day. B, C, D, and E don't change based on day or night. Even G and E are F-111 day or night above 10,000 feet. So, the only one that requires extra memorization is G during the day.
That only applies if you're in the pattern within half a mile of the runway. As soon as you leave the immediate vicinity of the airport you need 3-512. It's a special case that you'll just have to memorize.
This is just useless memorization with no real world application. Nobody knows how far from the clouds you are. You don’t know; other pilots don’t know; ATC doesn’t know. So dumb.
Avoiding a midair collision always seemed pretty fucking practical to me. Or knowing when I need to turn to an alternate or ask for svfr based on the Wx. And I don't think I'm particularly special knowing the approximate difference between clear, 005, 010, 020, and 050 by my solo. Especially with that useful altimeter they give me and the bases and tops I'm required to know for most flights (and is probably 91.13 info in any circumstance). To each their own though! Stay safe (and far away from me, please).
@@patrick5372 if you have to divert you’ll know by looking at it, you don’t need to know if the minimum is 500 feet or 1000 feet from clouds. If you need to ask for svfr - the controller will tell you that you can’t get in. In terms of flight visibility - above 10000 feet it’s just impossible to tell. A lot of complicated numbers to learn by heart. You’ll never need them. If you need FAA to tell you not to touch a cloud with your wingtip - memorizing numbers won’t help you either. And no, you don’t know your distances to every single cloud you fly by on you cross country, your altimeter won’t help you.
If cloud bases are reported at 3000 feet and you're at 2,900 and almost have a mid air with an IFR aircraft... I'll guarantee ATC will be calling the airport you land at, or tracking you down by your ADS-B data. lol.
@@TheFlyingZulu doesn’t matter how high or low bases are reported. Cloud clearances are from actual observed clouds, not from reported bases or tops. Completely irrelevant.
@@alk672 Sure... explain that to a ticked off IFR pilot, FAA rep, and an controller. lol. And I've love to hear what your DPE said if that's how you responded during any checkride...

Thank you for this. I’ve been struggling and this was by far the best video on this topic!
I've always liked starting with night minimum b/c C, D, E, and G are all the same below 10,000 feet at night. Then, G is the only one that changes during the day. B, C, D, and E don't change based on day or night. Even G and E are F-111 day or night above 10,000 feet. So, the only one that requires extra memorization is G during the day.
Great way to remember. Thanks for your videos, one of my go-to channels for aviation
He’ll yeah!
Thank you very helpful!!
Great presentation. Thanks
Logic is defo the way.
Let’s go!!!! Happy flying
Example of G above 1200 AGL?
Nice breakdown
Where does 91.155 (b) (2) fit in?
