Airspeed of military planes

Nozzles aft, Harrier approach speed will be in the 155kt +/-range. At 20
nozzles and auto flaps(normal for IFR final), you're somewhat slower but to
be honest I don't recall the airspeed because my primary reference was
always AoA. Depending on the type of landing you intend to make, once
you're in the visual environment, you transition to a higher nozzle angle
(60-75 depending...), and in some instances, STOL flaps where the flaps
program automatically as a function of nozzle angle. "On speed" for a
fixed-nozzle slow landing is around 110kts. The *very* slow rolling
landings you occasionaly see are called rolling vertical landings -- 60 kts
ground speed is the target but the transition to that speed will usually be
over the runway, not on approach final.

Airspeed limitation below 10000ft is usually 250kts unless you have been
authorized by the Administrator. However I guess it's a bit slow for
military fighters. So I am curious how fast military fighters fly in
the
real world. I guess it's very dangerous military aircraft fly much
fast
among civilian planes.



So how fast is short final in a F-14 or whatever? Always wanted to know.

You're right Frijoles, in the Bone the correct answer for "What airspeed do
you fly on final" is "I don't know/care. I'm flying 7 AoA as required by
the Dash One". There is however, a chart of airspeed and gross weights that
every pilot has and, IAW the Landing Checklist, every final must have an
airspeed computed.

Is the AOA indicator a piece of string like Wilbur and Orville had?

There is however, a chart of airspeed and gross weights that
every pilot has and, IAW the Landing Checklist, every final must have an
airspeed computed.

That's in case the AOA indicator goes T.U. :-)

Yes, kind of. It's such a fast, heavy airplane that we use yarn rather
than string. ;-)

No, but the yaw indicator on the F-14 is!

I've known generally what (the string) was for a long time but never
bothered to ask when it was referenced (primarily)? High alpha stuff?
Landing pattern? Single engine would be an obvious case...anything else?
More for "departure prevention," TF 30 "management" or both?

I never flew the Turkey, but probably all of the above.

I flew gliders with them, and they replaced the turn balance ball -- "step on
the knot".

We had a "yaw string" on F-4s in USAF. I don't recall if there was on
for the F-105. The main purpose in operational aircraft was during
weapons deliver and the most important weapons delivery with a yaw
concern was strafe or rockets.

Any yaw at the moment of release means the sight is pointing left or
right of the flight path and the weapons will go in the direction the
aircraft has imparted, not the place that the sight tells you. Yaw
left, shoot right.

Thanks -- had forgotten about sideslip and FF ordnance realignment with the
relative wind...

Good job JB, you compute an airspeed for the Bone. And so your point
is...*what* about landing the Harrier?
