Actions for battery hot light
- turn battery off and land as soon as practical
- if batt relay light comes on land immediate
Low fuel light
Appprox 50-75lbs fuel remain land immediate
Max operating pressure altitude is:
20000ft
Max sea level ambient air temperature
51.7 degrees C
decrease 2 degrees per 1000ft
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?
30 mins
VNE Below 3000 feet density
130 KIAS
or placarded whichever is less
Fuel QTY switch should be used to check which tank and when?
This will check the forward tank transferring to the main cell at approx 407lbs and below
Which boost pump runs off the battery?
The left one and will not turn off just because master batt is off must pull circuit breaker of fuel valve switch off
Battery hot light comes on
- Turn batter off
- land as soon as practical
- IF battery RLY light comes on as well land immediate
If both fuel pumps fail what may be the unusable fuel
It may be as high as 160lbs due to inability to transfer fuel from forward cells
Maximum sea level air temp for operation?
- 51.7 degrees C
- decrease 2 degrees per 1000ft
Pitot heat/anti-ice to be used in what conditions?
-In visible moisture below 5 degrees OAT
Generator Maximum continuous operation?
-90% DC LOAD
180 amps
Engine model for L3?
