Question 1

True or false? The AIR COND switch is available in both cockpits and is used to activate the air
conditioner compressor.

Answer 1

False. The AIR COND switch is located only in the front cockpit on the environmental control panel.

Question 2

True or false? Placing the vent control lever in the CANOPY position opens the defog valve.

Answer 2

False. The defog valve is opened by placing the DEFOG switch in the ON position.

Question 3

Which cockpit control and duct component controls whether warm bleed air is routed to the
footwarmers or defog outlets?

Answer 3

The front cockpit vent control lever adjusts the position of the cockpit selector valves to
route warm air to either the footwarmers or the defog outlets.

Question 4

True or false? The Temperature Control Switch Knob on the Environmental Control Panel controls
the temperature of both heating and defogging air.

Answer 4

True. The switch knob controls the position of the heat exchanger bypass valve which
determines the temperature of air for both heating and defogging.

Question 5

The safety valve will open to relieve excess cockpit pressure, regulating the pressure at 4.0
psi.

Answer 5

If cockpit pressure differential exceeds 4.0 psi, the ∆P regulator sends a signal to the safety outflow
valve. What does the safety outflow valve do?

Question 6

To provide enhanced protection against possible birdstrikes, the forward windscreen and front
transparency are thicker than the rear transparency. These two transparencies have been designed to withstand what type of birdstrike?

Answer 6

A 4-pound birdstrike at up to 270 KIAS.

Question 7

With the TEMP CONTROL switch in the AUTO position, the bypass valve diverts a portion of the
warm bleed air around the heat exchanger to be mixed with cooled air downstream of the heat
exchanger. This system automatically controls cockpit temperature between what temperature?

Answer 7

60° and 90° Fahrenheit

Question 8

Above what temperature will the amber OBOGS TEMP annunciator light?

Answer 8

If the temperature in OBOGS ducting exceeds

200° Fahrenheit.

Question 9

Which annunciator will light if the inflow air temperature exceeds 300° Fahrenheit?

Answer 9

DUCT TEMP Annunciator

Question 10

Above what temperature does the exchanger bypass valve move to full closed and thereby forcing maximum bleed air through the heat exchanger.

Answer 10

At a temperature in excess of 165° F

Question 11

A cockpit pressure differential of 3.6±0.2 psi is normally reached at what altitude?

Answer 11

18,069 feet

Question 12

True or false? Pressure for the anti-G system is supplied from an electrically driven pump.

Answer 12

False. System pressure is supplied by the engine right side bleed air port.

Question 13

Which oxygen pressure regulator concentration lever position supplies the highest possible oxygen
concentration?

Answer 13

The MAX position

Question 14

When is the canopy pressure seal inflated?

Answer 14

The seal is automatically inflated when bleed air inflow is available and weight is off the
right main landing gear.

Question 15

True or false? Aircraft electrical power must be available for the canopy fracturing system to
function.

Answer 15

False. The CFS requires no electricity to function.

Question 16

The T-6A Martin-Baker ejection seat is a zero-zero seat usable up to what altitude and airspeed?

Answer 16

35,000 feet and 370 KIAS

Question 17

How would you deploy the parachute if the automatic system fails?

Answer 17

Use the manual override (MOR) handle on the right side of the seat bucket.

Question 18

When activated, the emergency oxygen bottle will supply oxygen for how long?

Answer 18

Approximately 10 minutes

Question 19

Illumination of the CKPT PX annunciator indicates what?

Answer 19

Cockpit pressure exceeding 3.9 to 4.0 psi, indicating a problem in the pressurization
outflow system

Question 20

The CKPT ALT annunciator is illuminated, indicating the cockpit altitude has exceeded 19,000 feet. What ∆P reading should you expect to see?

Answer 20

Delta P less than 3.4

Question 21

An OBOGS FAIL annunciator should be accompanied by what other panel indication?

Answer 21

A flashing MASTER WARN switchlight on the instrument panel.

Question 22

Where does bleed air for T-6A heating, defogging, pressurization, anti-G and OBOGS come from?

Answer 22

Left and right engine compressor P3 ports

Question 23

True or false? The entire T-6A canopy is protected for birdstrikes.

Answer 23

False. Only the forward windscreen and front cockpit transparency are protected.

Question 24

If the ejection seat ADU mode selector switch is set to AUTO, when will the SSK deploy?

Answer 24

Approximately 4 seconds after seat/pilot separation

Question 25

True or false? The T-6A air conditioning system is electrically operated and is available when
electrical power is applied to the aircraft.

Answer 25

False. Air conditioning depends on an engine-driven compressor which only operates when
the: Engine is running; generator is on-line; AIR COND or DEFOG switch is ON

Question 26

Which control opens the bi-level flow control bypass valve?

Answer 26

The DEFOG switch opens the bi-level flow control bypass valve.

Question 27

Which annunciator will light if duct air temperature exceeds 300° F?

Answer 27

DUCT TEMP annunciator

Question 28

Emergency oxygen can be activated manually in the event of OBOGS failure. When does it
automatically activate?

Answer 28

Emergency oxygen is automatically activated during ejection.

Question 29

OBOGS will provide oxygen for how many hours of flight?

Answer 29

OBOGS is an on-board generating system and its duration is unlimited.

Question 30

True or false? The CKPT ALT annunciator indicates the cockpit is overpressurized.

Answer 30

False. It indicates a cockpit pressure altitude of 19,000 feet or higher, usually due to loss of
cockpit pressurization.

Question 31

In addition to the cold air vent on the center console in each cockpit, additional air conditioning
outlets are located where?

Answer 31

On the glareshield.

Question 32

When the ejection seat sequencer is set to SOLO, which seat will eject first?

Answer 32

Only the activating seat will eject.

Question 33

True or false? The anti-G system will activate only during negative-G maneuvers.

Answer 33

False. The anti-G system only activates during positive-G maneuvers.

Question 34

Which switch controls the flow of fresh air to the cockpit during ground operations and unpressurized flight?

Answer 34

The RAM AIR FLOW switch on the Environmental Control Panel controls the position of
the fresh air valve and thus the amount of air flow.
