"Good To Know" Info Flashcards
What is the fuel quantity that triggers the EICAS MSG: FUEL QTY LOW?
FUEL QTY LOW will show when there is less than 4500 lb (2041 kg) of fuel in the left or right main fuel tank.
Ref.: FIM 28-41 TASK 856
What is the minimum oil quantity before each flight?
If next Flight expected duration is 6 Hours or More or if Flight expected duration is unknown: 21.0 Quarts.
OR otherwise, a minimum of 18.0 Quarts.
Ref. B777 Daily Check
For a Daily Check the Engineer checks the Crew Oxygen pressure before a flight. What is the minimum psi indicated on the STATUS display?
1500 psi at 21°C (70°F)
NOTE: At outstations, if pressure is below 1500 psi, refer to FCOM to determine that quantity is sufficient for the scheduled flight.
Ref. B777 Daily Check
How the Ice Detector detects Ice?
The ice detector probe vibrates at approximately 40,000 Hz. The probe vibrates at a lower frequency when it collects ice.A heater for the probe turns on when the probe vibrates less than 39,867 Hz. The heater stays on until the probe vibration returns to its usual value or the heater operates for 25 seconds.
How the Eng Fire Detector distinguish an Overheat from a Fire?
As the temperature of the core increases, electrical resistance to ground decreases. The fire detection card monitors this resistance. If the resistance decreases to the overheat set point, an overheat indication occurs in the flight deck. There is a 7.2 second time delay for the overheat indication. If the resistance decreases more to the fire set point, a fire warning occurs. When the fire or overheat condition is gone, the resistance increases to the reset point and the flight deck indications go away.
What is the Takeoff and Landing Tire Speeds limitations?
Takeoff: 235 mph (204 kt)
Landing: 260 mph (226 kt)
Ref.: Boeing 777 AFM
For the Actual Landing Weight Calculation (OPT Landing Enroute), what are the max crosswind component including gusts for all Runway Copnditions?
- Dry - 45 knots
- Good - 40 knots
- Good to Medium - 35 knots
- Medium - 25 knots
- Medium to Poor - 17 knots
- Poor - 15 knots
Reduce crosswind by 5 knots on wet or contamitated rwys whenever asymmetric reverse thrust is used.
When using asymmetric thrust reverse you should reduce the crosswind component by 5 knots as per QRH. Does the OPT advice you that you exceeded the crosswind limitation if you select One Inoperative Reverser when performing the LDG Enroute calculations?
No!
If you have, for exemple, a runway condition Medium, but you are using asymetric thrust, your new crosswind limit is 20 knots. But the OPT doesn’t alert about it if you insert a 25 knots crosswind for example.
