Q

What is the CAUTION with regards to the rudder.

A

A full or nearly full rudder deflection in one direction followed by a full or nearly full deflection in the other direction, even at speeds below the design maneuvering speed, can dramatically increase the risk of structural failure of the vertical stabilizer or the rudder.

Q

Icing Definition - On the Ground and for Takeoff (without Visible Moisture)

A

Icing conditions also exist when the OAT is 10 C or below when operating on ramps, taxiways or runways where surface snow, ice, standing water or slush may be ingested by the engines, or freeze on engines, nacelles or engine sensor probes.

Q

What is the CAUTION that comes with the Icing Definition on the Ground or for Takeoff?

A

On the ground, do NOT rely on visual icing evidence or ice detector actuation to turn on the Anti-Icing System. Use the temperature and visual moisture criteria as specified above. Delaying the use of the Anti-Icing System until ice build-up is visible from the flight deck may result in ice ingestion and possible engine flameout.

Q

What is the CAUTION that comes with the Icing Definition In Flight?

A

Notwithstanding ice detector monitoring, the crew remains responsible for monitoring potential icing conditions and for manual activation of the Ice Protection System if icing conditions are present (known icing) and the Ice Detection System is not activating the Ice Protection System.

Q

What is TAT?

A

Total Air Temperature is the SAT (actual OAT) plus the temperature rise associated with high-speed flight due to heating of the air from compression. From a practical standpoint, TAT is the temperature the airplane’s skin feels, while SAT is the free air’s temperature (aka OAT). Temperature rise is proportional to the speed of the aircraft. At 0.8 Mach plus, an increase of 30 C can be expected which may be enough to prevent ice from forming.

60
Q

What is the first step (line) of the “Uncommanded Swerving on Ground” IAE

A

Control the aircraft using differential brakes and rudder

61

62
Q

What is the caution that goes with the “Uncommanded Swerving on Ground” IAE?

A

Do NOT actuate the steering handle since it will reengage the steering system and will disable the 7 degree maximum nose wheel deflection protection. This may cause the nose wheel to be steered up to its limit and may exacerbate the swerving effect.
