5.6. TAKEOFF
For 5000ft density altitude and above, or high ambient temperatures, a FULL RICH mixture
may cause rough running of the engine or a loss of performance. The mixture may be ad-
justed to obtain smooth engine operations.
Lean to maximum RPM at Full Throttle prior to take-off where airports are at 5000ft density
altitude or higher.
During climb, a rough method of correctly leaning is to slowly reduce mixture lever until an
increase of appr.ly 50-100 RPM is noticed at constant IAS or EGT reaches 1375°F mark.
1. Pitot HEAT: ON if required
2. Fuel pump: ON
3. Brakes: apply
4. Throttle: FULL and check approximately 2100
100 RPM
Engine proper performance at full throttle shall be checked early in the ground roll
in order to abandon take-off if necessary.
A rough engine, sluggish RPM increase or failure to reach take-off RPM are reasons
for abandoning the take-off. If the engine oil is cold, an oil pressure in the yellow sec-
tor is permissible.
5. Engine instruments: check parameters within the limits
6. Brakes: Release
7. Rotation speed V
R
: 60 KIAS
At safe height:
8. Flaps: retract (minimum speed 73 KIAS)
Expect to adjust pitch trim (pitch up) when retracting flaps after take-off.
9. Establish Climb rate V
Y
: 82 KIAS
10. Electrical fuel pump: OFF
11. Fuel pressure: check within limits
