Definition of Icing conditions
Icing conditions exist whenever the OAT on the ground for takeoff, or Total Air Temperature (TAT) inflight, is 10°C or below, and visiible moisture in any form is present (such as clouds, fog with a visibility of 1sm or less, rain, snow, sleet, an ice crystals).

46
Thrust Reverser Limitations
- Ground use only - Not authorized while taxiing - Full stop landings only - No go-arounds after deployment - Power-back is prohibited - Minimum reverse thrust must be used with the translating cowl open below 60kias - Idle thrust with the translating cowl closed at 30kias
47

50
Maximum TOGA power time (both engines operting)
10 minutes
51
Flex takeoff minimum thrust setting
No less than 25% less than full takeoff thrust
52
When can a flex takeoff be performed?
Only on an uncontaminted runway
53
When must ATTCS (automatic takeoff thrust control system) be on?
For all takeoffs and landings
54
Engine starter duty llimits
- 1st and 2nd attempts: 90* seconds on / 10 seconds off - 3rd through 5th attempts: 90* seconds on / 5 minutes off * = 120 seconds while in flight
55
Dry Motoring Cycle Duty Limits
- 1st attempt: 90 seconds on / 5 minutes off - 2nd-5th attempt: 30 seconds on / 5 minutes off - After 5th attempt, 15 minutes are required before the cycle can be repeated
56
APU starter Duty Cycle
- 1st and 2nd attempts: 1 minutes on / 1 minute off | - 3rd attempt: 1 minute on / 5 minutes off
57
APU minimum start temperature and altitude
-54ºC and 30,000’
58
APU altitude and other limitations
- 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
What is the difference between SAT and TAT?
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
When is TAS, TAT, and SAT accurate?
Above 60kias
61
When is the standby compass not valid/trustworthy?
When transmitting on VHF #1
62
Which kind of approaches cannot be done using IESS (Integrated Electronic Standby System, i.e. backup instruments)?
LOC back course approaches
