Pretty much any aircraft piston engine power chart shows that the
power does increase with altitude, IF the manifold pressure and rpm
are constant. But, if you have full throttle, the manifold pressure
will decrease with altitude, and thus the power will decrease.

Note that the tables are given for standard temperature: meaning at higher
altitudes the temperature is lower. Same manifold pressure + lower
temperature = more air. This is probably the main factor in increased power
at altitude.
Lower pumping losses (because maintaining a given manifold pressure at a
higher altitude requires a more open throttle) contribute.

At 65% and 2100 rpm, power stays constant while climbing at FT. Seems to
contradict Kevin Horton. Is the chart correct?

To Maintain constant power, correct manifold pressure approximately 0.17"hg.
For each 10F variation in carburetor air temperature from standard altitude
temperature. Add manifold pressure for air temperatures above standard;
subtract for temperatures below standard

| Subject: | AE FPS-Plus Help Wanted |
I recently obtained, second-handedly, an Aircraft Extras FPS-Plus (One of the Earlier
Flap Position modules). The seller didnt have the Users manual so I am
asking if anyone out there has an electronic copy of the Users Manual, or detailed
operating instructions for this controller that they could send me.
Any and all help is appreciated.
