Describe counter rotating prop
A prop on 1 shaft rotates in one direction while prop on other shaft rotates in the opposite direction
Describe contra-rotating props
When 2 props on one shaft rotate in opposite directions
What is VTOSS?
A speed greater than VMCA with a safety factor added to it.
Typical ice protection system for a twin
Carb heat
Ice boots
Anti ice and de ice systems
What is meant by drift down?
The AC is not able to climb or maintain an ALT (i.e. in event of OEI) and so the AC starts to descend. This descent is drift down.
What system(s) prevent inadvertently raising of the UC?
- Safety retraction switch - a safety px switch is fitted to the pitot system to detect impact (dynamic) air. When impact air is below 59-63kts the hydraulic pump circuit is deactivated.
- Weight on wheels (not on BE76).
Following OEI one engine flies in front of the other in S and L flight. Which eng is the front/leading engine and why?
The dead engine as the AC is side slipping to keep a straight line due to the yaw towards the live engine.
