Ejection Seats 1-57

Question 1

What is the ejection seat injury

risk definition, and what is the rate of injury rate estimated to?

Answer 1

LOW RISK; 5-10%

Question 2

True or False. Ejection seat: Injury probability increases with speed.

Answer 2

True

Question 3

The seat is capable of providing safe escape from ______ altitude, ______ speed, up to ______ feet at
speeds up to approximately ______ KIAS.

Answer 3

zero; zero; 35,000; 370

Question 4

During rear seat ejection, only the rear transparency diamond pattern is detonated

Answer 4

True

Question 5

When is emergency oxygen activated (ejection)?

Answer 5

when ejection is initiated

Question 6

After ejection, how is the seat stabilized?

Answer 6

the seat is stabilized and the forward speed is reduced by a drogue parachute,

Question 7

Should the canopy fracturing system fail, the seats will not eject

Answer 7

False. Should the canopy fracturing system fail, the canopy breaker mounted on the seat will shatter the canopy, allowing the pilot to safely eject through the canopy

Question 8

For high altitude ejections, an altitude sensing device and a G-limiting device delay seat/pilot separation and parachute deployment until the seat and pilot are between __________ and _________ feet MSL and at a safe parachute deployment speed.

Answer 8

14,000; 16,000

Question 9

When ejecting over mountainous terrain exceeding how many feet, should the manual override
(MOR) handle should be used to manually separate from the seat and deploy the parachute?

Answer 9

Above 8000 feet MSL

Question 10

What is the shape of the parachute canopy?

Answer 10

conical shaped canopy

Question 11

If the seat becomes unlocked from the catapult and slides partially up the rails, or completely out of the cockpit, ejection and/or parachute deployment is not possible

Answer 11

False. It is still possible, but

the ejection handle must be pulled followed by activation of the manual override (MOR) handle

Question 12

A manual override (MOR) handle is provided to initiate seat/pilot separation if the automatic system fails or if seat/pilot separation is desired above _______ .

Answer 12

14,000 feet MSL

Question 13

The emergency oxygen system supplies the pilot with oxygen for ________ or until ________

Answer 13

10 minutes; seat/pilot separation

Question 14

The emergency oxygen cylinder is sufficiently charged for flight if the contents gage pointer is anywhere within the _____ band (_________
psi).

Answer 14

black; 1800-2500

Question 15

The emergency oxygen cylinder will be charged to ____ psi minimum at ____ °F

Answer 15

1800: 70

Question 16

The emergency oxygen cylinder indicated pressure is affected by temperature changes. To approximate acceptable bottle pressure, add or subtract ____ psi for
each degree the temperature is above or below ____ °F.

Answer 16

3.5; 70

Question 17

Disconnecting the main oxygen supply hose from the CRU-60/P improves breathing capability by providing pressure relief and
improves anti-suffocation capability by reducing resistance

Answer 17

True

Question 18

Once activated, ejection seat emergency oxygen can only be shut off by resetting the green ring (left side of seat)

Answer 18

False. It cannot be shut off and will provide oxygen flow until the cylinder is depleted

Question 19

Whenever ejection for both seats is activated, a ____–second timer is initiated to allow the shoulder harness reel to retract the harness, and a _____-second timer is simultaneously activated to provide ejection separation

Answer 19

0.17: 0.54

Question 20

What is the time delay between the rear and front seat ejecting, when ISS is in BOTH?

Answer 20

0.37-second elapsed time

Question 21

Firing of one seat while the ISS mode selector is set to SOLO prevents the other
seat from firing.

Answer 21

False. It does not

Question 22

When the selector valve is set to automatic, the SSK is lowered automatically ____ seconds after seat/pilot separation, suspended on the lowering line.

Answer 22

4 to 6
