Q

Va Limits Rudder caution

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 Va, can dramatically increase the risk of structural failure of the vertical stabilizer or the rudder.

Q

Icing Definition on the ground for takeoff

A
  1. Icing conditions exist when the OAT is 10°C or below and visible moisture in any form is present (such as clouds, fog with visibility of one mile or less, rain,
    snow, sleet and ice crystals)
  2. 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

Ground Icing Caution

A

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 cockpit may result in ice ingestion and possible engine damage or flameout

Q

In Flight Icing definition

A

Icing conditions may exist whenever the Total Air Temperature (TAT), is 10°C or below and visible moisture in any form is present (such as clouds, fog with
visibility of one mile or less, rain, snow, sleet and ice crystals).

Q

IN flight ice Caution

A

Not withstanding ice detector monitoring, the crew remains responsible of monitoring potential icing condition and for manual activation of the ice protection system if icing condition are present and the ice detection is not activating the ice protection.

Q

Contaminated runways def.

A 
A runway is considered “Contaminated” when more than 25% of the required field length, within the width being used, is covered by:
• More than 1/8th inch (3 mm.) of:
— standing water,
— slush or
— wet snow.
• More than 3/4 inches (19 mm.) of dry snow.
• Compacted snow
• Ice
