Chapter 3 - Turn and Slip Indicators Flashcards
Why is a turn and slip indicator required?
In a banked turn, the compass system can become inaccurate
Turn and slip indicator combined with a stopwatch will allow the pilot to calculate an angular change in direction
What are the differences between the turn and slip rate gyroscope and other rate gyroscopes?
- Only one restraining spring is used
- Unnecessary for the rotor to rotate at a high speed
What is a rate one turn?
180° per minute or 3° per second
How does the rate of turn change the turning rate?
Rate number * 180° per minute
What problem is associated with a slip indicator where the ball is outside the turn?
Underbanked as centrifugal force is greater than gravity
Why are suppressors fitted to the DC operated turn and slip indicator?
To prevent electrical interference due to contact sparking
What is the main difference between a turn co-ordinator and a turn and slip indicator?
The gimbal is tilted, usually about 30° to the aircraft’s longitudinal axis
This makes the gyro precess during a roll as well as a yaw
What can the displacement of a turn co-ordinator gyro gimbal be used for on smaller aircraft?
Operate a wing levelling system
Gives an automatic stabilising effect for small changes in roll caused by air disturbances or gusts
What must be written on the turn co-ordinator face?
No pitch information
