P1 Flight Evaluation Flashcards
Dynamic Rollover
Definition
Susceptibility to a lateral rolling tendency
Translating Tendency
Definition
Tendency of a single main rotor helicopter to drift laterally in the direction of tail rotor thrust
Translating Tendency
Countermeasures
- Pilot Induced Cyclic
- Mast / Transmission Tilt
- Cyclic or Collective Rigging
Dynamic Rollover
Physical Factors
- Main and Tail Rotor Thrust
- Center of Gravity
- Crosswind
- Ground Surface Area
- Large Slope Angle
Dynamic Rollover
Human Factors

Emergency Equipment and Emergency Exits
- Green strip lights surrounding the doors used as emergency exits
- Green light at the corners of the emergency exit windows
- Exit lights near the door openings / jettison handles
WARNING LIGHT INDICATIONS - XMSN OIL PRESS
- Power - Reduce
- LAND AS SOON AS PRACTICABLE
If both indications are below 1.0 Bar:
- LAND IMMEDIATELY
SINGLE ENGINE FAILURE - IGE HOVER
- Collective Lever - Adjust to OEI Limits or below
- Landing Attitude - Establish
- Collective Lever - Raise as necessary to stop descent and cushion landing
After landing:
4. Affected Engine - Identify
5. Single Engine Emergency Shutdown - Perform
SINGLE ENGINE FAILURE - FLIGHT
- OEI Flight Condition - Establish
- Rotor Speed - Trim to maximum
- Affected Engine - Identify
- Single Engine Emergency Shutdown - Perform
- LAND AS SOON AS PRACTICABLE
Transverse Flow Effect
Definition
Differences in lift between the fore and aft portions of the rotor disk. Downward flow at the aft causes a reduced AOA, resulting in less lift. The forward half produces an increased AOA and more lift because airflow is more horizontal.
Dissymmetry of Lift
Unequal lift across the rotor disk resulting from the difference in the velocity of air over the advancing blade half and the retreating blade half.
