Describe aspect ratio.
Describe aspect ratio.
The ratio between the wing span and the mean chord line.
A high aspect ratio is associated with good lift to drag ratio, i.e.: Gliders.
A low aspect ratio is usually associated with fast aircraft, i.e.: Fighter jets.
What are the disadvantages of a swept wing?
What are the disadvantages of a swept wing?
Swept wings have:
-
Poor lift qualities
-
Higher stall speeds
-
Speed instability at low speeds
-
A wing-tip stalling tendency
What are the problems associated with icing?
What are the problems associated with icing?
Drag penalties (additional weight)
Less controllability
With 10 minutes to go to the destination, you're being advised by ATC that you will have to hold.

When does speed change from IAS to Mach?
At FL260
What is the relevance of the mass and balance document?
What is the relevance of the mass and balance document?
It’s an official document for the safety of the flight.
A copy of this document needs to remain on the ground.
What is Point of No Return (PNR)?
What is Point of No Return (PNR)?
The point during a flight at which an aircraft is no longer capable of returning to the airfield from which it took off due to fuel considerations.
Beyond this point the aircraft must proceed to some other destination.
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.
Where is thrust produced in a gas turbine engine?
Where is thrust produced in a gas turbine engine?
Mostly in the fan, but also from the exhaust nozzle duct.
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.
