Systems 2 - ECS, SEAT and CANOPY - review

Question 1

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

Answer 1

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

Question 2

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

Answer 2

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

Question 3

True or false? Place the vent control lever in the CANOPY position to open the defog valve.

Answer 3

False; to open the defog valve, place the DEFOG switch in the ON position.

Question 4

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

Answer 4

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 5

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

Answer 5

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

Question 6

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

Answer 6

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

Question 7

You normally reach a cockpit pressure differential of 3.6 ±0.2 psi at what altitude?

Answer 7

18,069 feet

Question 8

True or false? An engine-driven pump supplies pressure for the anti-G system.

Answer 8

False; the engine right side P3 bleed air port supplies pressure to the system.

Question 9

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

Answer 9

MAX.

Question 10

When is the canopy pressure seal inflated?

Answer 10

The seal inflates automatically when bleed air inflow is available and the aircraft’s weight is off the right main landing gear.

Question 11

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

Answer 11

False. The CFS requires no electricity to function.

Question 12

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

Answer 12

35,000 feet and 370 KIAS

Question 13

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

Answer 13

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

Question 14

When activated, the emergency oxygen bottle supplies oxygen for how long?

Answer 14

About 10 minutes

Question 15

Illumination of the CKPT PX annunciator indicates what?

Answer 15

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

Question 16

The CKPT ALT annunciator is illuminated, indicating the cockpit altitude exceeds 19,000 feet. What ΔP reading do you expect to see?

Answer 16

ΔP less than 3.4 PSI

Question 17

What indication do you expect to accompany the OBOGS FAIL annunciation?

Answer 17

A flashing MASTER WARN switchlight on the instrument panel.

Question 18

What supplies bleed air for heating, defogging, pressurization, anti-G, and OBOGS?

Answer 18

Left and right engine compressor P₃ ports

Question 19

True or false? The entire canopy is reinforced for birdstrikes.

Answer 19

False. Only the windscreen and front cockpit transparency reinforced.

Question 20

With the ejection seat ADU mode selector switch set to AUTO, when does the SSK deploy during the ejection sequence?

Answer 20

Approximately 4 seconds after seat/pilot separation

Question 21

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

Answer 21

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

Question 22

Which control opens the defog valve?

Answer 22

The DEFOG switch opens the defog valve.

Question 23

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

Answer 23

DUCT TEMP

Question 24

True or false? Emergency oxygen activates automatically in the event of OBOGS failure.

Answer 24

False; you must manually activate emergency oxygen in the event of OBOGS failure. Emergency oxygen activates automatically only during ejection.

Question 25

OBOGS provides oxygen for approximately how many hours of flight?

Answer 25

OBOGS generates oxygen from bleed air and so it is technically unlimited.

Question 26

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

Answer 26

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

Question 27

Which outlets provide cooled air conditioner air?

Answer 27

Cooled air from the evaporator/blower module discharges through an “eyeball” outlet in the console and duct outlets on the glareshield in each cockpit.

Question 28

When you set the interseat seat sequencer to SOLO, which seat ejects first?

Answer 28

Only the activating seat ejects

Question 29

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

Answer 29

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