Question

#1 Primary Servo or #1 Transfer Module Leak (#1 RSVR LOW) (#1 HYD PUMP) (BACKUP PUMP ON)

Answer 1

1*) SERVO switch- 1st OFF *2) Land as soon as practicable If BACKUP RSVR LOW caution also appears or backup pump fails: *3) Land as soon as possible If #2 PRI SERVO caution and/or HYD warning lgiht appears: *4) Land Immediately CAUTION- Switching the BACKUP Pump to OFF with weight on wheels and the #1 HYD PUMP caution light illuminated will result in loss of tail rotor control when the backup pump secures

Answer 2

1*) SERVO switch- 2nd OFF *2) Land as soon as practicable If BACKUP RSVR LOW caution also appears or backup pump fails: *3) Land as soon as possible If #1 PRI SERVO caution and/or HYD warning lgiht appears: *4) Land Immediately NOTE- Be prepared fro loss of pilot-assist servos

Answer 3

*1) SAS/BOOST pushbutton- OFF CAUTION- Up to 75 lbs of left pedal force will be required when hovering with boost servos off with starboard crosswinds. This value is significantly reduced with port crosswinds. CAUTION- Landings with BOOST SERO OFF on all single spot air capable ships should only be attempted if there is no large landing platform (LPD or larger) or shore base facility. CAUTION- Landing with aft cyclic movement corresponding with a nose up pitch rate has a significant effect on the instantaneous descent rate of the tailwheel and may cause an overload that ultimately contributes to the failure of the tail strut. If sufficient space and a suitable landing site exists, a landing may be conducted with slight forwards drift not to exceed 5 KGS.

Answer 4

*1) Safe altitude/airspeed- establish (waveoff/ITO as required) NOTE- If the AFCS DEGRADED caution appears during a night/IMC coupled hover or automatic approach, consideration may be given to continuing hover/approach if not disoriented or unstable.

Answer 5

* 1) PAC call- "STAB STAB STAB" * 2) Cyclic- Arrest pitch rate * 3) Collective- Do not reduce * 4) MAN SLEW switch- Adjust to 0 WARNING- It is possible for the stabilator to fail without illumination of the stabilator caution light and the associated aural warnings tone. In this case, the first indication of failure will be an uncommanded pitch change. WARNING- Re engagement of the automatic mode after a shutdown results in the automatic mode operating for 1 second. If a hardover signal to one actuator was the cause of the initial shutdown, and re engagement is attempted, the actuator will move before another disengagement is commanded. In this case, subsequent attempts shall not be attempted since it may result in additional stabilator movement. If acceleration is continued with the stabilator in the full down position, longitudinal control will be lost. The stabilator shall be slewed to 0 as airspeed increases over 40. WARNING- With large fixed stabilator angles, reduction in collective pitch results in increased aft cyclic requirements. Collective reduction during recovery from a trailing edge down stabilator flight condition should be minimal. If the stabilator becomes fixed at or near 0, nose-high attitudes may occur at slow speeds. WARNING- A combination of high airspeed/low altitude coupled with a runaway down stabilator (as indicated by a significant uncommanded nose-down pitch change) will necessitate immediate pilot action to maintain control of the aircraft. Primary consideration is to disengage the automatic mode by activating manual mode slewing as required. WARNING- At high airspeeds, immediate recognition and flight control input are essential to avoid an unrecoverable attitude. It is essential for the PNAC to slew the stabilator to 0 immediately to gain control of the aircraft. If acceleration is continued with the stabilator in the full down position, longitudinal control will be lost. WARING- Without stabilator auto mode, careful aircrew coordination to manually slew the stabilator is required to avoid undesirable and potential dangerous flight regimes and/or aircraft attitudes. In Manual Mode, the following are not recommended: 1) Swimmer deployments lower than 15' AGL 2) Night takeoffs, approaches, and landings (except one time landing following failure) 3) Automatic Approaches to a hover 4) Flight into known IMC 5) Simulated EP's including Practice Autos

Answer 6

* 1) Level the Wings * 2) Nose of Horizon * 3) Center the Ball * 4) Stop rate of climb/descent * 5) Control Airspeed

Answer 7

* 1) Safe Altitude/Airspeed- Establish * 2) Stabilator- Check position, slew as required * 3) APU Emergency Start procedure- Perform WARNING- Ensure airspeed versus stabilator angle limits are not exceeded. Stabilator automatic mode is inoperative NOTE- Stabilator Position Indicator will be inoperative with no power to the ac essential bus. Attempt to check visually. Note- The capability of slewing the stabilator is retained via the dc essential bus using battery power. Travel is limited to 35 deg if full down and 20 deg if full up when power failure occurs. Note- Loss of electrical power to the engine will result in engine anti-ice activation regardless of engine anti-ice or DE-ICE MASTER switch position, reducing maximum torque available by up to 18%. With a malfunctioning inlet anti-ice valve, torque available can be reduced by as much as 49%. Warning- Without electrical power to the dc Primary buses, the engine and inlet anti-ice valves are automatically opened. With an improperly operating engine inlet anti-ice system, a loss of up to 49% power available per engine is lost Warning- During an emergency where generators are secured intentionally or inadvertently, severe repercussions could result. In any case, actual flight conditions will dictate the immediate procedure to be followed. It may not be advisable to secure electrical power, which will result in the loss of AFCS, normal ICS, and flight and missions displays, prior to achieving VMC or landing/ditching.

Answer 8

If #1 or #2 Fuel Pressure Caution Light: *1) Fuel Selector Lever (affected engine)- XFD (DIR if currently XFD) If #1 and #2 Fuel Pressure Caution Light in DIR/DIR: * 1) #1 and #2 Fuel BOOST Pushbuttons- ON * 2) Land as soon as possible. Be prepared for a dual engine failure. If #1 and #2 Fuel Pressure Caution Light in DIR/XFD: *1) Fuel Selector Levers- Select opposite positions If cautions remain: * 1) #1 and #2 FUEL BOOST Pushbuttons- ON * 2) Land as soon as possible NOTE- Recommended airspeed is 80 KIAS to minimize Nr droop should dual-engine failure occur NOTE- Consideration should be given to performing applicable steps of Immediate landing/Ditching EP NOTE- Prolonged crossfeed operations will cause fuel quantity splits Note- #1/#2 FUEL PRESS caution will appear if a low fuel pressure condition exists. Illumination of this caution indicates either a possible malfunction of the engine driven fuel boost pump or an air leak in the system. Warning- Intermittent appearance of FUEL PRESS caution may be an indication of air leaking into the fuel supply lines, which can cause momentary fluctuation in engine power or flameout. If a FUEL PRESS caution appears, flameout is possible. Do not make rapid collective movements. Notes- Loss of engine due to low fuel pressure is a greater hazard than pressurizing a leak and creating a fire hazard.
