DQ-145 Flashcards
Q1. How is heading controlled after touchdown following a tailrotor malfunction e.g. fixed right or left pedal?
Upon touchdown, lower collective carefully and use brakes to control heading (-10 para 9.22.2 a&b)
Q2. Allowing large sideslip angles to develop following a loss of tailrotor thrust may result in what? Explain.
If large sideslip angles are allowed to develop causing low indicated airspeed, the stabilator will program down and make it more difficult to increase airspeed and to maintain adequate autorotative airspeed. (-10 para 9.22.1)
Q3. Operating in the Cairns traffic pattern at 1000’ MSL, conditions are 2000’ SCT, visibility 6, winds 030 at 10. Explain aircraft response to flight control inputs and procedures for a fixed left pedal including the preferred landing runway.
NOT DONE! RWY 36 to have a right quartering crosswind to help with heading control.
Q4. In cruise flight the main transmission oil pressure drops to 35 psi. Is this normal and if not what should be done?
Acceptable range is 45-60 PSI. Any drop or fluctuation outside of this range requires an entry on DA FORM 2408-13-1.
Q5. Following the pressure drop in question 4, an unusual vibration develops and RPM R begins to decrease with an increase of torque. What should be done?
A. Return to base and make an entry on DA Form 2408-13-1.
B. Monitor the situation and start a clock.
C. Reduce speed and perform an emergency APU start.
D. Adjust collective and land.
D. Adjust collective and land.
Main transmission failure. Decreasing % RPM R with increase in Q, with no engine malfunction.
Q6. Explain the importance of the Input Module during a single or dual engine failure.
The freewheel unit allows engine disengagement during autorotation, or in case of a nonoperating engine, the accessory module will continue to be driven by the main rotor.
