2b) IFR Malfunctions

The pod fuel delivery pressure display on the refueling control panel reads 50 psi steady.  What fuel component could cause this problem?

• Fuel surge suppressor

• Fuel pressure transducer

• Fuel flow indicating transmitter

• Fuel coupling on the reel leaking

The receiving aircraft is hooked to the refueling aircraft and is in the refueling range.  The fuel valve is selected to AUTO, fuel is flowing, but there is no fuel flow indication in the flight deck or at the pod. What fuel component would cause this problem?

• Fuel flow gauge

• Fuel surge suppressor

• Fuel flow transmitter

• Fuel pressure transducer

Everything is OK during refueling at the left reel, rewind is selected on the left reel and the hose does not rewind at all.  What hydraulic component is bad?

• Left boost cylinder

• Left rewind solenoid valve (valve 7)

• Left hydraulic power control valve (valve 14)

• Left reference pressure solenoid valve (valve 6)

The hose is in preset trail, you select response, the response test valve opened, electrically everything is OK, but you get no response.  Which hydraulic component is bad?

• Boost cylinder

• Reel control valve

• Hydraulic power control valve (valve 14)

• Reference pressure solenoid valve (valve 6)      

The reel control was selected to trail but nothing happened. The hydraulic PRESS is off and the stowed and locked light is illuminated.  What has failed?

• Reference pressure solenoid valve (valve 6)

• Hydraulic power control valve (valve 14)

• Hydraulic pressure switch

• Servo positioner

The hose is in preset trail.  The hose responds during the response test but when the receiving aircraft connects and pushes on the hose, the hose does not respond. Which hydraulic component has failed?

• Boost Cylinder

• Rewind solenoid valve (valve 7)

• Hydraulic power control valve (valve 14)

• Reference pressure solenoid valve (valve 6)

You select trail, valve 14 opened but the hose never starts to trail.  What hydraulic component failed?

• Boost Cylinder

• Reel Accumulators

• Reel pressure switch

• Latch release cylinder

The hose is in the refueling range but the fuel valve is still closed. There is no electrical power available to the fuel valve control relay.  What component failed?

• Fuel counter

• Fuel control valve

• Fuel range switch

• Fuel control valve relay

After refueling, the reel control switch is selected to rewind, but the hose stayed at preset trail.  The hydraulic power control valve and the rewind solenoid valve are de-energized. What component is faulty?

• Drogue stowed switch

• Drogue position switch

• Preset trail switch

• Rewind relay

The hose is rewinding but stops with about 2 to 3 feet of hose outside the pod. The most probable cause is _________

• Valve number 7 (rewind valve)

• Drogue position switch

• Drogue stop switch.

• Rewind relay
