State crew actions of the P* when responding to IIMC.
- Announce IIMC
- Transition to instruments
- Immediately initiate climb while establishing ACFT control
What are the crew actions for the P when responding to IIMC?
- Announce IIMC
- Monitor instruments to assist in recovery
- Announce positive climb, altitude, and heading
- Adjust transponder to emergency
- Tune NAV, radios, make calls
What’s the warning associated with engaging the upper modes if the ACFT encounters IIMC?
Crew should ensure ACFT is under control and positive climb is initiated BEFORE engaging upper modes.
State the caution associated with Task 1194: Perform Refuel Operations.
Extreme caution must be exercised when refueling ACFT due to fuel tank ventilation and filler neck limits. The high velocity of incoming fuel may cause fuel to flow backward and exit fuel cell
Why does it require more power to hover IGE versus OGE?
Induced flow velocity is increased requiring higher blade pitch angle to maintain the same angle of attack as IGE. Increase pitch angle creates more drag.
State the conditions that must exist simultaneously for settling with power to occur.
- Near vertical descent at 300 fpm
- Airspeed greater than ETL
- 20-100% power
- Insufficient power to arrest descent
During vortex ring state, roughness and loss of control occur due to what effects?
Turbulent rotational flow on blades/unsteady shifting of flow along blade span
State flight conditions conducive to settling with power:
- Steep approach with high rate of descent
- Downward approach
- Formation flying
- Hover above max hover ceiling
- Constant altitude control in OGE hover
For a single rotor helicopter what is the recovery procedure for settling with power?
Push cyclic for airspeed and/or lower collective if altitude permits
