FPS-Plus Description?
The FPS-Plus is
a full service, automatic, flap positioning system, . . Plus! In the fully
automatic step position mode, a “one button touch”, commands the flaps and
elevator trim to move. One touch moves the flap from programmed flap stop, to
programmed flap stop. Holding the flap button down for more than 1 second
commands the flaps to go to either the full up, or the full down position. The
FPS-Plus is fully user programmable from 2 to 10 flap positions. PLEASE read on
about the “PLUS” feature.
The “Plus”
feature and Pitch Stability
Have you ever
wondered what it would be like to adjust your flaps without the nose of your
aircraft pitching up or down? Perfect pitch stability is a very desirable
flight characteristic that many small planes do not have. After adjusting the
flaps, most pilots compensate for the pitch up or down by manually cranking in a
bit of elevator trim. We have all done it. With the FPS-Plus, your aircraft
can perform like the larger, more expensive aircraft with good pitch stability.
Your elevator trim will be automatically adjusted for every different flap
setting that you command. You may also adjust it manually if desired.
“FINALLY! , . . No
more manual tweaking on final approach to relieve the stick pressure!”
FPS-Plus - Elevator Trim Compensation
Advantages
"Aborted landings"
"Touch
& goes"
and "Slow Flight",. . . are all made much
easier.
With the FPS-Plus, the pilot can pay more attention to "flying the aircraft",
rather than tweaking the correct amount of elevator trim for every different
flap setting. If the pilot desires, he/she may manually adjust the elevator
trim after the automatic adjustment of the FPS-Plus has finished.
Flying is made much more enjoyable. Touch & goes, and aborted landings can be
accomplished so much faster and trouble free.
All you
have to do, is tap the "flap up" button once, and the flaps and the elevator
trim are automatically adjusted for you, to the next position up. If you desire
to retract the flaps fully, all you have to do, is press the "flap up" button
for more than 1 second. The flaps will be automatically retracted to their full
up position. The elevator trim is also automatically adjusted to your cruise
trim position. Can you imagine what it is like, . . flying your bird without
fighting any stick back-pressure in this situation?
What if the aircraft weight &
balance changes?
The FPS-Plus was designed so that it is very easy for the pilot to store a
new elevator trim position in flight, by simply pressing one button. While this
feature of the FPS-Plus is not needed for most two seat aircraft, it may be
desired for aircraft of 4 seats or more if the aircraft balance changes from
flight to flight significantly. To readjust the FPS-Plus to a new flight load,
for each flap setting, simply adjust your elevator trim manually, then press the
programming button. An new elevator trim position will be stored for that flap
position. The FPS-Plus will automatically adjust the elevator trim for each
flap setting thereafter. NOTE: (In most cases aircraft flight loads
will have to change significantly before the pilot needs to put in new elevator
trim values.)
OPERATION is EASY
One touch operation changes the flap position from
flap stop, to flap stop. It works the same in either direction.
A
long press, (1 Second) sends the flap to either the
full up, or the full down position.
IF you choose to operate the FPS-Plus in the "PLUS modes",
the elevator trim is also automatically adjusted for you for each and every
flap position.
If you ever need
to fine tune the elevator trim for different cruise
airspeeds or a clime configuration, you may. Just wait until the FPS-Plus finishes its automatic elevator trim adjustment.
You may then, manually adjust your elevator trim.
