Q

The active vibration control system avcs uses Force generators to counterbalance airframe vibration. This is accomplished by mechanically generating additional airframe vibratory loads out of phase with the main rotor-induced for prev vibrations such that the resulting cockpit/cab and vibration is reduced. The avcs maintains consistent vibration performance with varying rotor speeds from ___ through ____. An ____ advisory will appear when the system is not operating.

A

90 through 105

Q

What are the ground and flight indications for a load demand system malfunction

A

Ground:

EPCLs in idle - NG 3 to 4% higher than normal
EPCLs to fly - torque split (greater than 5% Q)

Flight:

Initial takeoff (during collective pull) - increased torque split (single malfunction)

Low power descent (lowering collective to minimum) rapid rise in engine NP and NR

Q

Explain Collective/Airspeed to Yaw (electronic coupling)

A

It is in addition to collective to yaw mechanical mixing. It helps compensate for torque effect caused by changes in collective position. It has the ability to decrease tail rotor pitch as airspeed increases and the cambered fin becomes more efficient; as airspeed decreases the opposite occurs.

Q

What is meant by the term cross-country flight?

A

A flight extending beyond a local flying area or within the local flying area, which is planned to terminate at a place other than the location of origin.
