OPERATING PROCEDURES
--------------------
Take-Off
1. Set flaps to 15 (first notch) for take-off.
2. Set trim to 0 if your using T&A. If not just set it to
neutral.
3. Advance throttle to full, as the aircraft accelerates to 100
rotate the nose up to about 15 degrees, and start your climb
at 100-106 Kts or so. As soon as you have a positive rate of
climb retract the landing gear. Upon reaching 400 Ft. above
ground level, lower the nose to level the aircraft off and let
it begin to accelerate. When the airspeed reaches 130 Kts
retract the flaps.
4. Accelerate and climb at 160 Kts. Climb at full power. Set the
trim as required.
5. Once you reach you desired altitude level off, adjust the trim
(T&A users -3840 seems about right).
6. Cruse - reduce the power to 75%. The aircraft should cruise
at about 250 Kts.
7. Landing - On an ILS approach cross the outer marker (about 5NM
from the airport) at 160 KTS. (44 % power and -1792 trim will
result in 170 Kts with the gear and flaps up in level flight).
Intercept the glide slope select the Flaps to 15 (first Notch)
and the gear down. Continue to slow (leaving the power set
where it was) until 145 Kts and select flaps 30 (second
notch). Make the final approach at about 110 to 120 Kts. I
found a power setting of 40% and the trim set to 0 or neutral
worked well, assuming a 3 degree glide slope. At about 50 feet
above the runway reduce the power to idle , flair the aircraft
and land. If you not using the ILS just make your final
approach at 120 Kts.
