Why do you need contingency fuel?
Why do you need contingency fuel?
Contingency fuel is carried to account for additional enroute fuel consumption caused by wind, routing changes or ATM: ATM/CNS restrictions.
How does an aerofoil work?
How does an aerofoil work?
An aerofoil is a body shaped to produce an aerodynamic reaction (lift) perpendicular to its direction of motion, for a small resistance (drag) force in that plane. It achieves this by accelerating the flow passing over it, and decelerating the flow passing under it. This change in velocity causes a change in pressure, which in turn generates lift.
Approach category speeds are defined by which formula?
Approach category speeds are defined by which formula?
This speed is defined to be equal to the greater of stall speed (Vso) multiplied by 1.3, or stall speed (Vs1g) multiplied by 1.23.
The landing configuration that is to be taken into consideration can be defined by either the operator or by the aeroplane manufacturer but is most commonly assigned by the manufacturer.
What can you tell about adiabatic lapse rates?
What can you tell about adiabatic lapse rates?
When considering a volume of air, adiabatic lapse rate is the temperature change that is caused by the vertical movement of the volume, andThe Lapse Rate is the rate at which temperature changes with height in the atmosphere.
The Environmental Lapse Rate (ELR) is according to ISA 2°C per 1000 feet increasing altitude.
For unsaturated air, the lapse rate is 3°C per 1000 feet, this is called the Dry Adiabatic Lapse Rate (DALR).
The Saturated Adiabatic Lapse Rate (SALR) is the rate at which saturated air cools with height and is, at low levels and latitudes, 1.8°C per 1000 feet.
What is a yaw damper?
What is a yaw damper?
Boots on the leading edges inflate (6 seconds) to break the ice dissipating it into the airflow.
Powered by the gyro pressure system.
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.
While climbing with a SEP, in what temperature range can carb icing occur?
While climbing with a SEP, in what temperature range can carb icing occur?
Carb icing can occur with temperatures as high 30°C and humidity as low as 50%, but it is more likely when below 20°C and high humidity, especially during low power settings.
Why don’t you want to fly your Seneca into a thunderstorm?
Why don’t you want to fly your Seneca into a thunderstorm?
Due to the structural damage that may occur in thunderstorms, due to hail, severe turbulence and severe windshear.
Besides that, lightning strikes may cause damage to electrical systems and severe icing may occur.
Are swept wings effective?
Are swept wings effective?
Swept wings are designed to be the most effective at high speeds. At low speeds, a swept wing produces less lift than its straight counterpart.
How does a jet engine/gas turbine work?
How does a jet engine/gas turbine work?
Forward motion forces air into the intake which is a convergent duct where it is compressed (causing a temperature rise).
Fuel is added and combustion takes place increasing the volume. The expanding gasses accelerate to the atmosphere through the exhaust duct nozzle producing a propulsive jet.
