What are the advantages of fuel injection vs a carburetor?
What are the advantages of fuel injection vs a carburetor?
Fuel injection provides:
-
Fuel free from vaporization ice
-
Better economy through metered delivery
-
More responsive and efficient engine
-
Less maintenance
What is the typical range of an NDB?
What is the typical range of an NDB?
Average range over land 20 - 25 miles.
Range for an NDB can be calculated with:
2√power output in Watts = Range (Land) 3√ power output in Watts = Range (Water)
If you climb to FL300 at a constant IAS of 250kts, what would happen to the TAS?
If you climb to FL300 at a constant IAS of 250kts, what would happen to the TAS?
TAS will increase.
What is lift?
What is lift?
Lift is the component of the total aerodynamic force perpendicular to the relative airflow.
Lift is generated when a streamlined body, such as an aerofoil, is placed in a flow of air.
If turboprops are more efficient aircraft, why do they not climb that high?
If turboprops are more efficient aircraft, why do they not climb that high?
Jet engines are designed to achieve their best specific fuel consumption at high rpm, which can only be achieved at high altitudes where the air density is low.
Thrust produced will be low enough to equal the required cruising thrust. Also high altitude gives the best operating conditions for the airframe i.e. minimum drag during the cruise.
Turboprops need relatively dense air for the propellers to work efficiently and at high altitude the density would be too low.
What does a bypass ratio of 11:1 mean?
What does a bypass ratio of 11:1 mean?
For every 1kg of air passing through the combustion chamber, 11kg of air pass bypass the combustion chamber.
Why is anhedral used instead on some aircraft?
Why is anhedral used instead on some aircraft?
Anhedral:
compensates for the wing sweep improves roll maneuverability
What would you do in the event of an engine failure below V1, and what would your initial actions be?
What would you do in the event of an engine failure below V1, and what would your initial actions be?
Assuming I'm performing single pilot operations:
-
power idle,
-
max brakes (and reversers if available),
-maintain directional control using rudder input,
-
After coming to a full stop set parking break.
-
Inform ATC 'Stopping'.
-
Initiate the appropriate process to diagnose the problem (ECAM, NITS DODAR, checklists....).
-
When performing multi pilot operations the actions performed by me will depend with my current role: PF, PM and/or CM1 CM2.
