MAIN
ECS operates with a range of what?
2-71 degrees C
With ECS FLOW switch in NORM the max torque is reduced by what?
Fuel flow increases by?
4% torque per engine
8 lbs per hour
With ECS temp in HOT and above 15* OAT Max torque is reduced by _____
5% torque per engine
With ECS flow switch in HIGH the max torque is reduced by ______ and fuel flow increases by _______.
7% torque per engine
45 lbs per hour
How do the fire sensors detect a fire?
They detect infrared radiation (fire), and when no blue light (sunlight) is detected they send a signal to the cockpit.
What may cause a false fire indication?
Sunlight filtered through smoke and haze, or at sunrise and sunset.
In the FIRE DETR TEST number 1 position, what is checked?
What is checked in the number 2 position?
The continuity of the three firewall-mounted detectors (No. 1 engine, No. 2 engine, and the APU) is checked.
The continuity of the two engine deck-mounted detectors.
How is thermal discharge indicated on the fire bottles?
Loss of the red plastic disc on the left side of the aircraft.
Using the APU to power the ECS will increase fuel consumption by what?
150lbs per hour
ECS will automatically shut down under what conditions?
- Engine C-PWR selected
- No. 1 or No. 2 Starter is engaged
- An ECS heating duct overtemp exists
When AIR SOURCE ECS/START switch is placed to ENG, the ECS will shut down when:
- A TGT of 851*C is reached
- Either ENG ANTI-ICE switch is placed ON
- The DE-ICE MASTER switch is placed to ON and ice is detected.
- An ECS underpressure situation exists
