 Ex 6. Straight & Level flight
Aim: To attain and maintain flight in a straight line, and at a constant attitude.
Airmanship:
- Lookout
- Regular checks - Fuel state/consumption rate/engine instruments/etc
Straight Flight:
- Visual reference point
- Regaining and maintaining visual reference point
- Use of yaw control to maintain balanced flight
Level flight, (Normal cruise power):
- Power required dependant on load carried
- Attitude appreciation and control
- Use of in-flight trim control (if applicable)
- Hands-off trim
- Inherent stability
- Use of altimeter to check level
Level flight, (Varying power settings and IAS):
- Power provides height
- Angle of attack provides speed
- Power and angle of attack combine to give performance
Attitude control:
- Use of pitch control to maintain constant attitude to achieve constant I.A.S.
Difference between 3-axis aircraft, and weightshift aircraft:
- Normal input to the pitch control, will change the attitude on both 3-axis and
weightshift aircraft. But:-
- With 3-axis aircraft, to change airspeed, aircraft nose must be raised or lowered,
because wing is fixed to fuselage, so nose attitude changes with deliberate
airspeed change
- With weight-shift aircraft, to change airspeed, wing is moved independently of
fuselage, so nose attitude remains almost constant with deliberate airspeed
change (provided that Angle of Attack is changed slowly)
