    weight reduces climb performance. • Weight and Balance–Pilots who do not check center of gravity limits may experience difficulty trimming or controlling the aircraft, which could lead to a loss of control in-flight. Equipage The avionics and other equipment ... pilot workload. A pilot flying an aircraft in these conditions might consider aircraft without an autopilot an “A” hazard. • Inoperative Equipment–Inoperative equipment triggers an “A” hazard. For example, an inoperative landing light may make night operation more hazardous, even…

    flight. Using the deferral provision of 14 CFR, part 91, section 91.213(d), the pilot determines whether the inoperative equipment is required by type design, 14 CFR, or ADs. If the inoperative item is not required, and the aircraft ... safely operated without it, the deferral may be made. The inoperative item shall be deactivated or removed and an INOPERATIVE placard placed near the appropriate switch, control, or indicator. If deactivation or removal involves maintenance (removal always will), it must…

    aircraft to move down and the nose to move up. In spite of the opposing directional movement of the trim tab and the elevator, control of trim is natural to a pilot. If the pilot needs to exert constant back ... pressure on a control column, the need for nose-up trim is indicated. The normal trim procedure is to continue trimming until the aircraft is balanced and the nose-heavy condition is no longer apparent. Pilots normally establish the desired…

For example, should a component fail that is not listed in the MEL as deferrable (the rotor tachometer, engine tachometer, or cyclic trim, for example), then ... Deferral of maintenance is not to be taken lightly, and due consideration should be given to the effect an inoperative component may have on the operation of a helicopter, particularly if other items are inoperative.

Many newer systems cannot be engaged without the completion of a self-test. The pilot should also be familiar ... damper should be off for takeoff and landing. There may be additional restrictions against its use with one engine inoperative. Most yaw dampers can be engaged independently of the autopilot…
