T-39 NATOPS EXAMINATION

1.         If you see the red disk ruptured during preflight, at least one fire bottle has been dumped into one of the engines.  False.

RED -  at least one vented overboard due to overheat when ruptured

YELLOW - at least one discharged into the engines

GREEN - O₂ vented overboard

2.         The emergency gear system needs hydraulic pressure for lowering.  FALSE.

The gear will be unlocked and than lowered by gravity.

3.         After pulling the emergency brake handle you will not have ANTI SKID available.  TRUE

4.         Which is the false statement concerning the ignitors?

a.            The Ignition switch controls ignitor #3

b.            Both ignitors are duty cycle limited

c.            Ignitor #6 is on during stalls, starts and airstarts

Duty cycle: 2 min ON, 3 min OFF, 2 min ON, 23 min OFF

5.         If the wing mounted boost pump fails, the centriful part of the engine driven fuel pump will supply suction feed upto 15,000 feet?

6.         The maximum fuel imbalance for T/O and LDG is 200#, 400# during level flight.

7.         To balance fuel, the tank x-feed valve needs to be closed.  The pump x-feed valve opens up.  The wing mounted fuel pump in the heavy tank stays energized and the pump in the light tank goes offline.

8.         Which of the following is not actuated by the main hydraulic system?   Ans: FLAPS

9.         The minimum EPR for using the ANTI ICE is 1.5.

10.       If the following conditions are encountered during flight the ANTI ICE should be switched on.

Answer: visible moisture, OAT +5°C/-20°C

11.       What is the normal position for the PITOT switch on deck?  OFF.

12.       At what speed will the NWS disengage? 60 KIAS.

13.       What is the maximum IDLE EGT limit?  515°C.

14.       What is the AOA readout for landing? 18 Units, Amber donut.

15.       What is the maximum X-wind limit for a full flap landing?  25 KIAS.

16.       What VOR data can be obtained with the double needle?  VOR-2 azimuth

17.            Prohibited maneuvers:

a.            What is the maximum EGT for climbout?  780°C for 5 miniutes

b. What is the maximum load from SL to 30,000 FEET with only one generator online?  0.8

 18.       After an airstart the affected generator can not be reset until the AIRSTART switch is OFF.  TRUE.

 19.       The fire extinguisher system should not be tested for more than once within 10 min.

 20.       What is the corrective action when the ANTI SKID FAIL light illuminates?  Recycle switch.

 21.       What happens when you land with the ANTI SKID system ON with only AUX hydraulics usable?

 Ans: The use of the ANTI SKID can lead to rapid depletion of pressure.

 22.       What is the corrective action during EMER PRESS ops when the CABIN HOT light illuminates?  REDUCE right throttle setting

 23.       During cold weather grund ops use the ANTI ICE to the maximum extend possible.  False.

 24.       Use of the ANTI ICE during ground ops for extended period of time leads to structural damage of the aircraft.  True.

 25.       If the DC generator fails, the corresponding AC generator fails as well.  True.

 26.            Delamination, distortion or bubbling of the windshield are signs of windshield heating control failure.  True.

 27.       The walkaround O₂ bottle is located behind the co-pilot's seat.

 28.       The cockpit FIRE EXT is located behind the pilot's seat.

 29.       The right FIRE PULL HANDLE repositions the direction valve to the right.  False.

 30.       If either GEN fails, you will loose both mission busses.  Mission A can be regained by placing the mission bus switch to EMERG.  True.

 31.       The battery HOT light illuminates at 150°F

 32.       The instrument inverter is rated at 1000V.

 33.       The AC windshield generators provide power to the windshields only.  True.

 34.       The maximum airspeed for lowering the gear is 180 KIAS.

 35.       The maximum airspeed for lowering the flaps is 180 KIAS.

 36.       The IDLE oil pressure is 35 PSI.

 37.       Fuel heater operation is limited to 1 min per 30 minutes.

 38.       Without windshield heating the airspeed below 10K is limited to 250 KIAS.

 39.       The cabin air dumb & safety valve provides a maximum differential of 9.1.

 40.       The green OXYGEN disk ruptures at a pressure between 2500-2700 PSI.

 41.       The use of the CABIN TEMP AUTO setting regulates the cabin temperature between 60°F and 80°F.

 42.       What indicates that a EHSI needle receives no valid information?
Ans:  Flashing needle RED/WHITE, than needle disappears

43.       The T-39 radar is powered by the Mission Bus A.  True

44.       What is the primary reference for engine performance?  EPR.

47.       With a dual generator failure in flight, turning the Pitot Heat Switch on will heat up which Pitot Tube?  Left

48.       Can both Fire Pull Handle be pull out at the same time?  No.

49.       When will the HYD Fail audible warning comes on?

a.            Weight on wheels & either Engine Master switch is ON.
