28
Q

Actions for battery hot light

A
  • turn battery off and land as soon as practical

- if batt relay light comes on land immediate

29
Q

Low fuel light

A

Appprox 50-75lbs fuel remain land immediate

30
Q

20000ft

31
Q

Max sea level ambient air temperature

A

51.7 degrees C

decrease 2 degrees per 1000ft

32
Q

After 3 attempsts at start you are unable to get the machine started- how long do you need to let the machine rest before restarting?

A

30 mins

33
Q

VNE Below 3000 feet density

A

130 KIAS

or placarded whichever is less

34
Q

Fuel QTY switch should be used to check which tank and when?

A

This will check the forward tank transferring to the main cell at approx 407lbs and below

35
Q

Which boost pump runs off the battery?

A

The left one and will not turn off just because master batt is off must pull circuit breaker of fuel valve switch off

36
Q

Battery hot light comes on

A
  • Turn batter off
  • land as soon as practical
  • IF battery RLY light comes on as well land immediate
37
Q

If both fuel pumps fail what may be the unusable fuel

A

It may be as high as 160lbs due to inability to transfer fuel from forward cells
