FADEC Failure Warnings
1. In the event of a FADEC failure, abrupt reduction
in collective can lead to activation of the engine overspeed system. In the event of an overspeed, it is probable that the tail rotor system will experience an overtorque. Main rotor RPM must be maintained within normal limits to prevent overspeeding the rotor and/or overtorquing the T/R system.
2. Aggressive maneuvering in the FADEC Manual Mode is likely to result in a M/R overspeed or underspeed and possible loss of acft control.
3. Failure to switch to manual mode will cause the M/R to droop or overspeed as collective is in increased or decreased.
82
Engine Overspeed Warning
WARNING
Severe contamination of the P1 nozzle screen will result in increased fuel flow and may cause engine surge and activation of the engine overspeed trip logic. Reverting to FADEC MANUAL MODE may be ineffective. Pilot should execute the appropriate emer proc for ENGINE OVERSPEED, but should be fully prepared to autorotate if the N2 RPM is uncontrollable in the MANUAL MODE.
83
FADEC Degrade Warnings
WARNING
1. The FADEC shall only be operated in automatic mode for flt operations.
2. Operations of the FADEC in manual mode in flight is prohibited, except for emer operations and training. In the case of an emer, land as soon as practicable. Maintenance checks on the ground of the manual mode are authorized.
84
Transmission Oil Hot or Low Pressure WARNING
WARNING
Engine power must be maintained throughout the approach and landing to prevent seizure of gears in the transmission. DO NOT AUTOROTATE.
85
Ground Resonance During
| Engine Starting
1. EMER Shutdown.
| 2. Remain strapped in and seated until rotors stop.
86
Armament WARNINGs
WARNING
During any weapons system malfunction. Keep the aircraft oriented downrange and away from personnel and equipment until the problem is under control.
WARNING
The maximum weight outboard stores for the four- station weapons platform is either 450 or 650 pounds. If jettison is attempted with a full store and only one side is jettisoned, the lateral CG may exceed normal limits.
