  • Takeoff with a single bleed air source requires isolation valve closed until 1500 feet AGL or until clear of takeoff obstacles (whichever is higher). Ref: [AFM, §01-36-10]
    What are the restrictions for takeoff with a single bleed air source?
  • Wing anti-ice operation with a single bleed air source is restricted to single ECS pack operations. Ref: [AFM, §01-36-10]
    What are the restrictions for wing anti-ice operations with a single bleed air source?
  • 32,000 feet. Ref: [AFM, §01-36-10]
    What is the maximum altitude for wing anti-ice operations with a single bleed air source?
  • 0.85M. Ref: [AFM, §01-36-10]
    What is the maximum airspeed for wing anti-ice operations with a single bleed air source?
  • 44.5 psig minimum. Ref: [MTM, ATA 36, p. 32]
    To what pressure does the manifold pressure regulating shutoff valve (MPRSOV) regulate?
  • 14 psig. Ref: [MTM, ATA 36, p. 35]
    Below what pressure will the High Pressure Shut Off Valve open during cruise flight, allowing the use of 8th stage air?
  • 24 psig. Ref: [MTM, ATA 36, p. 36]
    During descent, to what pressure set point will the High Stage Valve be set?
  • 35 psig. Ref: [MTM, ATA 36, p. 36]
    During single pack operation, to what pressure set point will the High Stage Valve be set?
  • The 8th stage valve is controled to maintain a maximum of 700°F at the pre-cooler inlet and the fan air valve to control the pre-cooler outlet to 500°F. Ref: [PAS, p. 13-4]
    How is bleed temperature regulated for wing anti-ice operations?
  • The fan air valve is controlled to adjust pre-cooler outlet to 400°F. Ref: [PAS, p. 13-4]
    How is bleed temperature regulated when wing anti-ice is not in use?
  • Controlled by L/R ENG BLEED switches, regulates pressure to 44.5 psig minimum, spring-loaded-closed. Ref: [MTM, ATA 36, p. 15]
    What controls the Manifold Pressure Regulating and Shutoff Valves? What does it do? How does the valve fail?
