Normal Procedures
SOFT FIELD TAKEOFF
Flaps 18 Degrees (Second Notch)
...................................................... ................... Trim Tab ............... Set for Takeoff
Full Back Pressure to Relieve Arplane Weight
Apply Slowly
** NOTE **
Once breakaway is achieved and taxi has begun, maintain airplane momentum to avoid becoming
bogged down in soggy terrain.
Accelerate until airplane breaks ground. Atter breaking ground:
Stay in Ground Effect and Accelerate to
Vx
................................................... 84 mph (73 kt)
Landing Gear
.................................................................................................................. Retract
** Establish Positive Rate of Climb **
Accelerate to Vy ..................... ................... ........................................................ 105 mph (91 kt)
Flaps
......................... .. ......... Retract
Power
As Required Above 1000
ft AGL
Continue Climb at Best En Route Speed
.................................................... 120 mph (104 kt)
The figures for
Vx and Vy are based on a 2800 pound gross weight. Both Vx and Vy decrease
approximately one rnph for every 100 pounds that the airplane is below maximum allowable gross
weight.
Vx increases approximately 0.25 rnph for each 1,000 foot increase in density altitude above mean
sea level.
Vy decreases approximately 0.75 rnph for each 1,000 foot increase in density altitude above mean
sea level.
CLIMB
Best Angle-of-Climb Speed (Vx) .................................... .... .................................. 84 mph (73 kt)
Best Rate-of-Climb Speed (VY)
.................................................................... 105 mph (91 kt)
Best En Route Rate-of-Climb Speed ................................................................. 120 mph (104 kt)
Cylinder Head Temperature

Mixture
..................... .... ........................................................................ Adjust With Ascent
Electric Fuel Pump
..................................... ... ....... Off at Desired Altitude - Check Fuel Pressure
** NOTE **
Best en route rate-of-climb speed decreases approximately 0.75 rnph for each 1,000 foot increase
in density altitude above mean sea level.
When en route below 5,000 feet MSL, always return mixture to full rich before increasing power
settings. Above 5,000 feet MSL, adjust mixture as required as over enriching mixture at high
altitude will result in engine roughness.
