Airspeed of military planes

Not if the minimum safe airspeed for descent/landing/touch-and-go is greater
than 250.

Which in a BUFF means you probably shouldn't be attempting a landing. Better to
bail out in such circumstances. Bottom line, a BUFF will *always* be able to
comply with 250 below 10 on recovery.

So what point were you trying to make?

I was making the point that the BUFF has an FAA waiver when taking off, but not
landing. Trying to show how these military waivers are not always as clear cut
as a blanket coverage.

What is the waiver for and why was it issued?

Most waivers are for safety. Probably a B-52 with a good load needs all the
speed it can get on climbout.

But a waiver isn't needed for safety. The regulation permits an aircraft,
civil or military, to be operated at the minimum safe airspeed if the
minimum safe airspeed for any particular operation is greater than the
maximum speed otherwise permitted.


§ 91.117 Aircraft speed.

(a) Unless otherwise authorized by the Administrator, no person may operate
an aircraft below 10,000 feet MSL at an indicated airspeed of more than 250
knots (288 m.p.h.).

(b) Unless otherwise authorized or required by ATC, no person may operate an
aircraft at or below 2,500 feet above the surface within 4 nautical miles of
the primary airport of a Class C or Class D airspace area at an indicated
airspeed of more than 200 knots (230 mph.). This paragraph (b) does not
apply to any operations within a Class B airspace area. Such operations
shall comply with paragraph (a) of this section.

(c) No person may operate an aircraft in the airspace underlying a Class B
airspace area designated for an airport or in a VFR corridor designated
through such a Class B airspace area, at an indicated airspeed of more than
200 knots (230 mph).

(d) If the minimum safe airspeed for any particular operation is greater
than the maximum speed prescribed in this section, the aircraft may be
operated at that minimum speed.

True. But normally 250 is adhered to for civilian types in the U.S. until
ATC is advised of the necessary speed and authorizes it. I currently teach
the MD-80 and on those that can go up to 159,500# for Take Off the minimum
maneuvering speed for a clean wing is 260 KIAS. We teach to set 250 in the
autothrottle window for takeoff. Bank angle 15 is also set for takeoff.
250 is OK with 15 degrees of bank. When ATC agrees to the higher speed (for
aircraft separation purposes), we set the higher speed and then increase
bank angle to 30 degrees. If an immediate turn is mandatory for safety we
can extend leading edge slats (which reduces maneuvering speed by about 40
knots) and go to 30 degrees of bank at 250.

Exactly. A BUFF at 488,000 pounds GW, below 250 KIAS would be a handful.

A waiver for safety serves no useful purpose.
