Answer 12

Np ovsp test re-references 96% rather than 120% and flames out engine. If Np speed decreases when either switch is pressed individually, the opposite test switch may be faulty. Failure of an engine to automatically relight when both OVSP TEST A and B are pressed simultaneously is possible. The engine should be restarted using normal procedures and the check should be performed again. If the engine automatically relights on the second attempt, the engine is acceptable. If the engine fails the test twice consecutively, maintenance action is required.

Answer 79

The MH-60R is considered to be hovering in ground effect at radar altimeter altitudes at or below 45 feet.

Answer 80

Nr: For a given gross weight, there is one ideal rotor rpm that will provide the minimum rate of descent. As rotor rpm is allowed to build above ideal, rate of descent increases. As rpm decreases below ideal, rate of descent decreases. This means that a heavy aircraft actually descends slower in a steady-state autorotation than a lighter one. In an actual autorotational flare, the pilot may choose to allow Nr to increase above optimum for descent. The higher the Nr when executing the final recovery, the more kinetic energy is available in the rotor system for the collective pull that will cushion the landing as Nr decays Airspeed: Minimum ROD - 75 KIAS.* Maximum glide airspeed of approximately 95 KIAS. *A decrease or increase in airspeed from this value results in an increase in rate of descent

Answer 88

1-Per (4.3Hz): Main Rotor out of balance, Worn/loose control rod bearings, Malfunctioning blade damper. Feels like a lateral oscillatory roll to the pilot. At high speeds, one per-revolution vibration will most likely be felt as a vertical vibration. 1.44-Per (6.5Hz): Caused by an initial aerodynamic upset that is amplified and maintained as a result of an SAS and Pilot-Induced Oscillation (PIO) in the longitudinal cyclic. 4-Per (17.2 Hz): Caused by the dynamic response of the main rotor blades to asymmetrical blade loading. Felt as a combination of vertical and lateral shake at the same frequency. Tail Shakes (5 cycle/sec): Tail shake is an aerodynamic excitation of the first lateral bending mode of the tail pylon in certain flight regimes. This vibration will be felt as a random impulse around the yaw axis Tail Rotor Drive Shaft Vibrations (Hi Freq): Generally, these vibrations are caused by an unbalanced drive shaft, bad bearings, or a failing tail/intermediate gearbox. These vibrations can be identified during a ground run by feeling the tailcone and can also be felt as a "buzz" in the pedals. One Times Tail Rotor Speed (20 Hz): due to tail rotor imbalance, damage, loose hardware, pitch change link bearing wear, or loose tail or intermediate gearbox, and is not easily isolated by the pilot.

Answer 112

INS is worldwide, passive, and self-contained.The primary disadvantage of INS is that the information provided is precisely accurate only for a short time, as it is eventually susceptible to inaccurate position and velocity solutions. GPS is worldwide, passive, and employed to provide very precise and regular position, velocity, and time information updates to the INS to preclude navigational errors. The disadvantages of GPS are: it is not a self-contained system (relies on satellites for information acquisition), it is vulnerable to jamming and spoofing, and it is incapable of providing aircraft heading and attitude information. Without GPS, an INS-only solution will eventually exhibit geosituational and positional errors due to the drift inherent in any INS. drift rate???
