1
Q
- What is the definition of dynamic rollover?
A
The susceptibility of a helicopter to a lateral rolling tendency.
2
Q
- What conditions must be present for dynamic rollover to occur?
A
Pivot point, rolling motion, exceeding the critical angle
3
Q
- What is the Critical angle?
A
The angle which if exceeded, recovery is impossible
4
Q
- What physical factors aid to prevent dynamic rollover?
A
- Main rotor thrust
- Asymmetrical loading
- Surface condition
- Slope
- Tail rotor thrust
- CG/Low Fuel
- Cross winds
5
Q
- What are the other factors that affect dynamic rollover?
A

- Roll rate
- Lateral loading
- Left pedal input ( creating tailrotor trust)
- Cross wind
6
Q

7

8
Q

- Mast bumping
- Personal Limits
- Sliding
9
Q
- What control input aids in preventing dynamic rollover?
A
Smooth moderate collective application
10
Q
- What is the definition of LTE?
A
An uncommented rapid right yaw that does not subside of its own accord, and if not quickly reacted to will cause loss of aircraft control.
11
Q
- What is the Note for LTE?
A
Pilot must anticipate the variations, concentrate on flying the aircraft and not allow yaw rates to build
12
Q
- What are the wind regions
A
-
Weather cock
- (120-240 degrees) the aircraft will attempt to weathervane into the wind, causing a gradual left and right yaw rate.
-
Vortex ring state
- (210-330 degrees) Causing inboard vortices to develop on the tail rotor. The aircraft will have Pitch, Roll, and Yaw excursions, causing heading impossible to maintain and increasing pilot work load.
-
Disk vortex
- (280-330) Vortices caused by the main rotor are directed over the tail rotor at airspeeds between 10 – 30 knots. Aircraft will experience an uncommented rapid right yaw.
13
Q
- What are the factors that contribute to the onset of LTE?
A
- High gross weight
- High DA
- N2 (power) droop
- Low forward airspeeds
