  2. CAU compressor outlet temperature above 500 F
  3. CAU turbine inlet temp above 250 F
  4. Cockpit press failure, only when the CABIN press alt ind exceeds 24,500’

Q

“F PRES” caution

A

Fuel tank pressurization failure, fuel boost pump failure, or one or both ENGINE switches set to OFF.

If fuel tank pressurization is lost, two inward relief valves allow ram air to enter the tanks.

If both boost pumps fail, a bypass valve will allow the engine driven pump to draw fuel directly from the bottom of the negative G compartment.

Q

“HYD” caution

A

HYD system pressure low.

Illuminates when either HYD 1 or HYD 2 pressure drops below 1600 psi. Extinguishes when both HYD 1 and HYD 2 pressure is at least 2000 psi

24
Q

“LP PUMP” caution

A

Engine driven low pressure fuel pump failure/outlet pressure low or low pressure fuel filter is clogged.

Illumintates when pressure drops below 35 psi

25
Q

“M FUEL” caution

A

Manual fuel system is selected.

There is no automatic control of N1 rpm, N2 rpm, or EGT. Fuel metering is accomplished by direct movement of the throttle. Take extreme care to prevent exceeding rpm and EGT limits.

26
Q

A

A warning or caution light has been activated

27
Q

“NWS” caution

A

30
Q

“RAT” caution

A

RAT is extended

31
Q

“SEAT” caution

A

50
Q

“NWS HI” advisory

A

Nose wheel steering is in high gain

51
Q

“POSITION” advisory (T-45C MFD Display)

A

Displayed when positional data is invalid. Heading and velocity data will not be presented on displays. If a restart is attempted, the GINA will attempt an alignment until attitudes are valid. Ground alignment requires 3 minutes. In-flight restarts require the aircraft to be in straight and level non-accelerated flight. Shipboard alignments require up to 18 minutes.

52
Q

“READY” advisory

A

N1 ≥100 rpm in correct direction and igniters on
