Transitions Flashcards
You have just entered the hover, describe your actions to complete before entering the transition:
Alignment marker (in line with duty RWY)
Dep Brief:
- Power (Cat X hovering with X FLI)
- Wind (From ATIS)
- Plan (T/O for R/L circuits RWY XX abort to RWY prior to fly away or circle to land after flyaway)
Lookout (Clearing turn)
R/T “TAIP XX, Spot 5, ready”
Explain your actions to transitions into forward flight for an IGE take-off:
Taxi: Hover forwards until ETL (10-15KTS)
Attitude: Set Accelerative once past ETL
Power: Hover FLI +0.5
Maintain until 150ftAGL @ 65KTS
Attitude: Maintain 65Kts
Power: 7FLI
How does a pilot know they have passed ETL?
- The pilot will experience a slight buffet and begins climbing
- Most notable around 10-15kts
Explain your actions to transitions into forward flight for a standard take-off:
Attitude: Accelerative (disc does not go below the horizon)
Pause: To prevent balooning
Power: Hover FLI+1
Maintain until 150ftAGL @ 65KTS
Attitude: Maintain 65Kts
Power: 7FLI
List the aerodynamic effects during transition from the hover to forward flight:
Height loss
Flap back and inflow roll
Effective translational lift
Tuck under
Torque reduction
Explain “height loss” during transition
Initial height loss as an accelerative attitude is selected, amount of height loss depends on how far the total rotor thrust is moved
Explain “flap back” and “inflow roll” during the transition
As IAS increases, there will be a tendency for the aircraft for nose up (flap back) and roll right (inflow roll)
Explain “Tuck under” and its effect during transition
As downwash on the horizontal stab reduces with increased airspeed the aircraft will pitch nose downå
Explain “TQ reduction” during the transition
As airspeed increases the vert stab will counter the TQ of the rotors reducing the requirement for left pedal, reducing total TQ
Explain the process for the pre departure clearing turn
- Climb from 4ft hover to 10ft hover
- Turn about the mast 360º
- Reenter 4ft hover
