Gulfstream V Systems Review
OXYGEN
- How can you tell if the oxygen cylinder manual shutoff knob has been turned off?
- Pressure switch between the tank regulator and check valve monitors pressure in the supply line and will display an amber "crew oxygen off" or a "pax oxygen off" CAS message
- Overboard discharge will occur when regulated oxygen pressure exceeds _________ PSI, Cylinder pressure exceeds ____________ PSI, or oxygen temperature exceeds __________F.
- 90 PSI, 2600 PSI, 225 Degrees
- True or false: A passenger breathing oxygen will not deplete the crewmembers supply.
- False: The two supply cylinders join on a common supply line to all occupants.
- Crew and passengers masks are not approved for use above ________ feet.
- 40,000
- Passenger masks will not provide sufficient oxygen for prolonged operation above ________________ feet cabin altitude. Prolonged operation above ________________ feet cabin altitude with passengers aboard is not recommended.
- 34,000, 25,000
- In the auto position the passenger masks will automatically deploy when sensed cabin altitude reaches ________________ feet.
- 13,000
PNEUMATICS
- The first set point regulates high stage pressure from ____ to ____ psi for descent, holding, or vmin operation to provide adequate air flow at low power settings.
- 14 to 22 PSI
- A high stage regulation set point is also available to increase airflow during single pack operations. during single pack ops, it is reset to ___ PSI. If mid stage pressure falls below __PSI, the high stage bleed valve will open and regulate at __PSI.
- 35, 35, 35
- THe final possibility for high stage regulation occurs when wing a/i is on. if the temp is less than ____F at the precooler inlet, the controller will command opening of the the high stage bleed valve to achieve ____ F.
- 620 F, 620 F
- If a single manifold pressure valve or a single wing a/i valve is on, bleed air is cooled to maintain a maximum of ____ F degrees at the precooler outlet sensor.
- 500 F
- The ___________________ monitors precooler outlet temperature and modulates the opening of the fan air valve as required.
- Bleed air controller
- The high stage bleed air valve is controlled by the ______________.
- Bleed air controller
- True or false: As long as the fifth stage bleed air supply meets air pressure demands the high stage bleed air valve will remain closed.
- True
