Allows verification and storage of last known position.
What are all of the Anti-Ice rain checked limitations (4)?
1.Holding in icing conditions with with Flaps
- Don’t operate wing anti-ice on the ground when OAT is above 10c
- Do not use wing anti-ice as a substitute for ground driving/anti-icing and inspection procedures which are necessary to comply with operating rules
- Do not operate weather radar during fueling, near fuel spills, or near people
Air systems: what is the checked limitation ?
With engine bleed air switches on, do not operate the air conditioning packs in HIGH for takeoff, approach, or landing.
Air systems: what is the checked limitation note?
The fire protection non-normal procedures (QRH) take precedence over the statement regarding no air conditioning pack in HIGH during takeoff, approach, or landing. The CARGO FIRE and Smoke or Fumes Removal checklists require the operating pack switches to be placed in HIGH in order to increase ventilation for smoke removal
Checked limitations: Flight controls first 3 of 6?
- Do not extend flaps above 20,000’ PA
- The ALTERNATE FLAP position switch must be in the OFF position for 15 seconds before reversing the direction of flap movement. A complete cycle is movement from position 0 to 15 and back to 0. Then need 5 minutes off.
- In flight do not extend the speed break lever beyond the flight detent
Checked limitations: Flight controls last 3 of 6?
- Do not use speed brakes in flight below 1,000’ AGL
- In flight, do not use speed brakes with greater than flaps 10
- 700 - Do not operate the aircraft at speeds in excess of 320 kt at weights over 143,000 lbs if the speedbrake wing load alleviation system is inoperative.
Check limitations: min and max fuel temp?
Min fuel tank temp -37c
Max fuel tank temp +49c
Note: Jet A freeze point is -40c and other listed fuels freeze at lower temperatures
Check limitations: Fuel distribution note 5.
Main tanks must be full if the center tank quantity is greater than 1,000 lbs
- 1,000 lbs may be retained in the center tank provided the effects of weight and balance have been considered.
Check limitations: Fuel distribution note 6 &7:
- Center tank fuel pumps must be ON for all operations with more than 1,000 lbs of fuel in the center tank.
- Some MEL items can override this limitation.
