Standard rate turn in Boeing 757?

Can anybody here tall me what the standard rate of turn is in a 757? Is it the
same as small palnes, i.ei, is it universal at 360 degrees in 2 minutes?

I've got someone telling me the Boeing 757 that hit the Pentagon did some
impossible turn before flying into the building, and it sounds like a turning
descent to me.

Any help would be appreciated.

The big guys don't do standard rate turns, because that would involve too
high a bank angle. Instead they just do 30 degree banks.

As for what they're capable of, remember Tex Johnson(sp?) barrel rolled
the 707 prototype (the "Dash-80"). If you don't care if the plane is
usable again after the maneuver, I'm sure you could do a lot more abrupt
maneuvers than that.

That'd be the remote controlled 757, flown by Mossad agents into the
Pentagon in an attempt to discredit Islam, right?

You got it.

I am a former student pilot (lost interest after moving constantly set me
back), and I need help from someone with ATP experience on this one.

Surely a 757 can make a descending turn 270 degrees in 2.5 minutes? Maybe, it's
not what an ATP would do to passengers, but it's not some plane-stressing move?

The move, before the crash, sounded like a spiraling descent, or an emergency
descent.

Any help would be appreciated, even if it's to point me to someone who can give
me the answers.

Hm....30 bank is new info to me. I always thought it was
a 4 minute turn for the big & fast guys.

Learn something new everyday!

Not necessarily... +1-G is +1-G.
The airplane doesn't know what attitude it's in as long as the proper
g-loading is maintained throughout the maneuver. The only variable is
the pilot's level of skill.

Standard Rate is Standard Rate for all aircraft. Three degrees
per second. However, when flying under Instrument Flight Rules
(IFR), and a standard rate turn is specified, aircraft with a
Flight Director/Autopilot installed are permitted to use the
maximum rate of turn commanded by the FD/AP which in the case of
the Boeing a/c that I flew, was about 25 degrees angle of bank
with the flaps up and 30 degrees angle of bank with the flaps
down. During the commencement of an Emergency Descent, the flight
manual called for a bank angle of 45 degrees to aid in getting the
nose down and eliminating negative "g"s.

Actually, an aileron roll, Paul. I know his book, ghost written by
another, says barrel roll, but the tape shows it's an aileron roll.

Among non-fliers, all rolls are "barrel rolls," just as all loops are
"loop-de-loops" and among Southerners, all Northerners are
"Damnyankees."

From Aerodynamics for Naval Aviators

n=1/cos(bank angle)

n= load factor in G's

ROT=(1,091*tan(bank angle))/V
r= v^2/(11.26*tan (bank angle)

ROT= rate of turn in degrees per second
r= turn radius in feet, divide by 6078 ft/nm to get nm.
V= velocity, knots

At 250 knots and a 30 degree bank this would be a 2.51 degree per second
turn. It would take 107 seconds to make a 270 turn.
