Final Approach B734

I dunno much about flying jets, but I remember someone once told me on
a jet it's the other way around to a light a/c.. In a Cessna you use
power to control rate of descent and attitude to control speed but on a
jet it's power = speed and attitude = rate of descent.

I remember hearing the same thing. Now having done my IFR license, you
always stay on the forward part of the curve where power = airspeed and
attitude = descent rate (power + pitch = performance). sO It's the same
for light a/c as well. it just depends on what part of the power curve
you are on and IFR a/c (in general) want to stay on the forward part of
the curve.

Well....you got that wrong! I post the following paragraph quoted from
"Aerodynamics for Naval Aviators".

The above relationship states that, for a given weight airplane, the
rate of climb (RC) depends on the difference between the power available
and the power required (Pa- Pr), or excess power. Of course, when the
excess power is zero (Pa-Pr=0 or Pa = Pr), the rate of climb is zero and
the airplane is in steady level flight. When the power available is
greater than the power required, the excess power will allow a rate of
climb specific to the magnitude of excess power. Also, when the power
available is less than the power required, the deficiency of power
produces a rate of descent. This relationship provides the basis for an
important axiom of flight technique: "For the conditions of steady
flight, the power setting is the primary control of rate of climb or
descent".

And, of course.....In steady flight (climbs, descents, and level
flight), Angle of Attack always equals Airspeed.

Hi Bob!
Thanks for the post. I appreciate the input.

Another thought - I use XP 8.5 and there is no 737 supplied with it,
and some of the models I have tried don't seem to work too well, maybe
they don't like 8.5. Anyway, maybe try a 737 from another author ???

I knew I was going to screw that up. I should have kept my mouth shut
and thought about it a LOT more. Thanks for the correction.
