-54ºC and 30,000’

58
Q

APU altitude and other limitations

A
  • Max operating altitude: 33,000’
  • Max bleed altitude: 15,000’
  • Max engine start assist altitude: 21,000’
  • No APU time limit between 662-717ºC (amber range)
  • In flight there is no automatic APU shut down if EGT exceeds limits
59
Q

What is the difference between SAT and TAT?

A

SAT is Static Air Temperature, or the temperature of undisturbed air arounds the aircraft (i.e. OAT). TAT is Total Air Temperature which is the Static Air Temperature plus the temperature rise associated with high-speed flight. TAT can be measured by probe on the outside of the aircraft as the high speed causes adiabatic compression and heating of the air around the temperature probe. Knowing TAT, SAT can be computed which is required to calculate True Airspeed.

60
Q

When is TAS, TAT, and SAT accurate?

A

Above 60kias

61
Q

When is the standby compass not valid/trustworthy?

A

When transmitting on VHF #1

62
Q

Which kind of approaches cannot be done using IESS (Integrated Electronic Standby System, i.e. backup instruments)?

A

LOC back course approaches
