I almost thought I needed my eyes checked for misreading a W for an M. After looking again, it's aliasing in the video that distorts the vertical legs of the M fairly heavily -- still looks like a W even after knowing it's not! That's my story ... Anyway, Mach number makes a whole lot more sense now ... thanks for seeing past the confusion! ~john Nose — indeed, that’s exactly the area I was referring to.

Anyway, Mach number makes a whole lot more sense now … thanks for seeing past the confusion!

But I won't. N Lex I think the confusion is with “W”

The numbers on the bottom left hand quadrant of the HUD are from top to bottom

Alpha ?鬱
Mach M
Current G G
Max G (No symbol used)

Time

Methinks it ain’t “W” they are talking about, but “M”

It’s the Mach, boys, and if I were a hater, I’d say something somewhat snarkey about it being a Hornet and that’s why you never see anything above 1.0.

But I won’t.

I'm crystal clear about AOA and how/why the pointy end of the plane is not the velocity vector direction. But, I don't see what W is actually measuring. After watching the video again, there were alphas ranging near 0, up to the high 20's, yet W only ranged from 0.33 up to 0.80 (non-coincidentally to the alphas). Seems like a ratio of sorts, but, its not obvious of what. Thanks, ~john Maybe this is beyond the scope of the comments for plane pr0n, but, I don’t quite get it.

The velocity vector - looks like a circle with wings and a tail - is where the airplane is actually going. The difference between the two is mostly due to angle of attack, a measure of the angle between the relative wind and the mean chord line. Sideslip, yaw and crosswinds may also play a (usually) smaller role. If you've ever seen the video of that late 80's/early 90's crash at the Miramar airshow, the FA-18's nose is pointed (waterline) way up in the sky, even as his flight path (velocity vector) runs him into the turf. Same principle. The “W” is the “waterline,” a representation of where the plane is pointing along it’s longitudinal axis.
