Angle of attack

[Flasher]

AOA seems to be erroneous and a lot overestimated. For landing you have over 25º despite your re around 12/13º visually… it should not exceed 18ō more less.

[Rongor]

It's because AoA is displayed in "units", not in degrees. It's in the manual.

[Rainmaker]

Not to mention, your landing AoA is on you.  There is no bug here.

An angle mesured with units not degrees why not …. The real aircraft display AOA the same way ?

That is indeed real life.

Yes, CPU is used in the real aircraft.  AoA + 10 essentially

Many reasons...one easy one is to avoid negative numbers.   There exist some more complex reasons that I won't bring up because I don't even really know how to explain them.

Your approach should be at 21 units, BTW, not 23 (unless you're flying a specific approach profile with specific purpose) and definitely not 25 since that is tail-strike territory.

FWIW comparing the cockpit AoA units to the AoA degrees readout in both TACView and the bottom info bar in external views, it would seem that the units are basically degrees of AoA + 10. I.e. 11.5 units of AoA = 1.5° AoA, 20 units of AoA = 10° AoA.

Based on the training mission's suggestion of holding between 20-22 units of AoA, that would put the landing AoA of the F-15E to around 10-12 degrees, which sounds fairly normal.

For starters, negative numbers mean someone could misread "-6.0" as "6.0".  An all positive scale is unambiguous

[GGTharos]

Agreed.  And yes, approaching at 20-22 CPUs (so just ride 21 all the way in) is the standard 'as per the manual' approach AoA

What does CPU stand for?

I think it's something mundane like "Cockpit Units"  

[GGTharos]

Yep, it's that mundane
