It appears to be very helpful to wring the last bit of performance out of a short field landing too. I've enjoyed watching the guy from Costa Rica fly into some amazingly tight and short strips using the AoA as a primary indicator.

There’s a reason Navy pilots fly AOA during the approach and landing on the carrier.

The AOA indicator is in the pilot’s line of site. And the Landing Signal Officer can see another indicator on the nose of the plane - typically on the nosegear door or strut.

All you Navy guys out there - please correct any of this if I’m in error.

Mike -

Great explanation, thanks - I'm new to flying with an AoA gauge and other than .6 = Vref I have only a vague understanding of it. You taught me something today!

However...

There is no relation between bank angle and stall speed. None. I'll fully admit this is an issue that gets me on my soap box...

One of the big benefits to AoA is that it isn't referencing a static stall speed and will adjust for Gs and the increase in stall speeds that Gs bring on.

You are correct.

I should have said my unaccelerated stall speed is ...

There is no stall speed at 0 G.

I had never used an AOA before I bought my CJ. Went through Type rating and mentor time without ever utilizing it. I fly out of a 3,000 ft runway and have learned to use it. What a great tool.

And a great explanation on the decimal relation on an AOA Mike.

Kinda. The importance of AOA in a carrier landing is for something call hook to eye. It’s the literal distance from the pilot’s eyes to the end of the hook. There is a minimum hook to ramp distance the LSO needs for a safe landing and not being on speed messes that up. Further, a flat AOA (aka fast) increases the likelihood that you miss the wires and bolter. A high AOA (aka slow) increases the chance of an inflight engagement which can seriously damage the plane and arresting gear. My LSO knowledge is getting rustier by the day, but that’s a quick 101.

Not sure about Navy, but all of the Navy/Marine types in my reserve USAF squadron flew the same. AOA was everything. In the pattern we would calculate an expected approach speed based on configuration and weight, but you flew AOA. F4, A10, F16. You could actually drag an F16 tail with too high an AOA on landing. (you probably wouldn't be flying again soon if you did this)

You actually got from KTUS (2500MSL) to FL410 in 32 minutes according to your track log on FA.

You were still pulling 350fpm at FL410 and you averaged 1250fpm getting there with no step climb...in a 501 with reversers.

You got a JATO on that thing? Spill the beans! (Or rig mine the same way. Lol.)
