4.4.3.
PROPELLOR CARE
Full throttle runups over loose gravel are especially harmful to propellor tips. When
takeoffs must be made over a gravel surface, it is very important that the throttle is
advanced slowly. This allows the airplane to start rolling before high RPM is
developed, and the gravel will be blown behind the propellor rather than pulled into
it. When unavoidable small nicks appear in the propellor, they should be immediately
corrected.
4.4.4.
CROSSWIND TAKEOFF
Takeoffs into strong crosswinds are normally performed with the minimum flap
setting necessary for the field length, to minimize the drift angle immediately after
takeoff. With the ailerons partially deflected into the wind, the airplane is accelerated
to a speed slightly higher than normal, and then pulled off positively and smoothly to
prevent possible settling back to the runway while drifting. When clear of the ground,
make a coordinated turn into the wind to correct for drift.
4.4.5.
CRUISE
Normal cruising is performed between 75 % and 90 % power. Continuous cruise
should not be above 3150 RPM. Flights should be planned at 22 litres per hour with
45 minutes reserve, with appropriate allowances for wind conditions which will assist
in determining the most favourable altitude and power setting for a given trip.
4.4.6.
CROSSWIND LANDING
The limiting crosswind velocity of 14 knots has been demonstrated at FULL Flap.
However, in strong crosswind conditions use the minimum flap consistent with the
strip length available.
Use the Wing Low technique right through to touchdown and land on Mains first.
