4.11 Level Flight
Altitude, direction and airspeed are the flight parameters to be kept during
straight and level flight.
About 90% of your lookout should be paid to the observation of the airplane
attitude against the horizon. Remember the airplane nose position on the
horizon after stabilizing the airplane. Monitor deviations from that position
and use short inputs to eliminate wing banking. A position of bank indicator
ball indicates to you if the airplane is flying correctly or in a skid or a slip. To
correct a skid , slightly apply pressure to the rudder on the Same side as
the ball. Deviation from the desired heading may also be seen on the
magnetic compass.
Any changes of engine speed affect the airplane pitch attitude and may be
corrected by longitudinal control or elevator trim, then the trim should be
adjusted to stabilize flight.
10% of your lookout should be used to pay attention to your flight and
engine instruments (look at them from time to time).
Use the elevator trim to balance longitudinal control forces, no change of
pitch should occur in stable air after the release of the control stick. Since
the airplane is fitted with a fixed (ground adjustable) trim of aileron control
(trim tab on the right aileron) there is only a narrow airspeed range (cruise)
within which the airplane is laterally balanced. The aileron trim tab
deflection may be adjusted on the ground. If the airplane banks to the right
in flight, then bend the tab slightly up.
You can find the level flight performance in Section 5. of the Aircraft
Operating Instructions ( Airplane Flight Manual ):
•
Calibrated airspeeds CAS at the set engine speed and given flight
altitude (with the altimeter set to the standard pressure 1013 hPa,
29.92 inHg ) and at a manifold pressure (boost) in case of in-flight
variable pitch prop (refer to the text below).
•
Table of IAS-CAS-TAS speeds at set engine speed and given flight
altitude.
•
Table of airspeeds, fuel consumption, endurances and ranges.
