Assignment 3
Textbook Assignment: “Canopy System”; “Pressurization and Air-conditioning
Systems.” 2-8 through 3-2.
Learning Objective:
Recognize the operation,
emergency jettison
procedures, and components
of the sliding canopy
system.
3-1. What type of canopy is used on
the A-6A aircraft, and which of
the following methods is normally
used to open and close it?
1.
Clamshell, manual
2.
Sliding, electrical
3.
Sliding, hydraulic
4.
Clamshell, pneumatic
3-2. When the canopy will not open by
its normal system, it can be
opened by what other method?
1.
Pneurnatically with the
emergency switch
2.
Electrically with the
emergency switch
3.
Mechanically through linkages
4.
Hydraulically with the hand
pump system
3-3. When the canopy is emergency
jettisoned, what method is used
to fire the jettison cartridge?
1.
Electrical
2.
Pneumatic
3.
Hydraulic
4.
Manual
3-4. From how many positions on the
aircraft can the canopy jettison
cartridge be fired?
1.
One
2.
TWo
3.
Three
4.
Four
3-5. (Refer to figure 2-7 in the
text.) What valve prevents air
battle pressure from escaping
overboard if a leak develops in
the air filler valve?
1.
Check
2.
Relief
3.
Air release
4.
Vent bleeder check
3-6. Should leakage occur in any one
of the air release valves, what
prevents inadvertent firing of
the jettison cartridge?
1.
The check valve
2.
The relief valve
3.
The flow regulator
4.
The vent bleeder valve
3-7. What is the purpose of the manual
override feature on the vent
bleeder valve in the jettison
system?
1.
To bleed off pressure after
testing the system
2.
To bleed off excessive,
pressure that builds up after
servicing the system
3.
To bleed off excessive
pressure that builds up from
thermal expansion in the
system
4.
To vent excess pressure
overboard during servicing of
the svstem
Learning Objective:
Recognize the purpose and
operation of the canopy
seal system.
3-8. A canopy seal system provides an
airtight seal between the canopy
assembly and the aircraft
structure to maintain cockpit
pressurization.
1. True
2. False
