18. Forces acting on an aircraft (Turning) Flashcards
The horizontal component of lift that holds the aircraft in the turn is called …….. force
centripetal
When the aircraft is turned in level flight, lift must be increased so that its vertical component balances ……..
weight
In a turn, bank angle is controlled by the …….., back …….. is required on the control column and rudder is used to keep the turn ……..
ailerons; pressure; coordinated
When rolling into a turn, rudder pressure is used in the same direction as ailerons to prevent any adverse ……..
yaw
The increased angle of attack in a turn not only means that lift is increased, but also ……..
drag
The increase of drag means that in level turn, there will be a loss in speed unless …….. is increased to counteract it.
power (or thrust)
Load factor is the …….. being generated by the wings divided by aircraft ……..
lift; weight
In a 30-degree banked level turn, the load factor is ……… and the pilot will feel 15% heavier. In a 60-degree banked level turn the load factor is …….. and the pilot will fell …….. ‘g’.
1.15; 2; 2
At any given airspeed, the radius of turn (increases / decreases) as bank angle increases.
decreases
State the angle of bank needed to achieve a rate-1 turn if the aircraft is flying at 130 kt.
20 degrees
If the aircraft is climbing and a turn is entered with power and airspeed remaining constant, the rate of climb will (increase / decrease / stay the same)
decrease
An aircraft tends to (roll into / roll out of) a climbing turn.
roll into
If the aircraft is descending and a turn is entered with power and speed remaining constant, the rate of descent will (increase / decrease / remain the same).
increase
In a descending turn, the inner wing has a …….. angle of attack and the aircraft will therefore tend to (roll into / roll out of) the turn.
higher; roll out of
