ABBREVIATED CHECKLIST
TAKEOFF (5568 lbs.)
Flaps: Up
Elevator trim: 0%
Rudder trim: +40%
Aileron trim: +35%
Apply power smoothly to 34" Hg (88%)
Liftoff speed: 115 mph (185 kph) IAS
Takeoff roll: 20 seconds
Note: This aircraft has a substantial amount of torque roll; although the stall speed is quite low at 85 mph, and the craft will want to lift off sooner, hold the nose down and let flying speed build to at least 115 mph where the runway length allows. This will allow you to gain aileron authority so as to minimize the roll when the aircraft lifts off. A good deal of right rudder and aileron will be needed until climbing speed is reached.
CLIMBING
Initial Climb: 2,500 fpm (12.5 m/s) at full power/2400 rpm/145 mph IAS.
Normal Climb: 145 mph (235 kph) IAS @ 34" hg/2200 rpm.
Rate of climb @ climb power: 2262 fpm (11.3 m/s)
LANDING (5059 lbs.)
This aircraft tends to float in ground effect so the landing touchdown speed is very important to a short ground roll. It is also very sloppy in slow flight so a deft hand at the controls is critical.
Gear extension: 150 mph/242 kph IAS
Flap extension: 150 mph/242 kph IAS
Full flaps at 140 mph/225 kph IAS
Approach speed: 115 mph/185 kph IAS
Over airfield boundary: 105 mph/169 kph IAS
Touchdown at 90 mph/145 kph IAS
