What is a Rhumb Line?
What is a Rhumb Line?
A line across the surface of the earth that cuts all meridians at the same angle. i.e. a track of constant direction.
A straight line on a Mercator chart.
Why do we calculate mass and balance?
Why do we calculate mass and balance?
To be within aircraft design limitations with regards to:
Structural limitations
Stability
Take-off and landing performance
Why do jet aircraft fly as high and fast as possible?
Why do jet aircraft fly as high and fast as possible?
Because the air is less dense thus the TAS is higher for a given power setting and for this reason modern jet aircraft are designed to be most efficient at high altitude.
When does speed change from IAS to Mach?
When does speed change from IAS to Mach?
At FL260
What is the maximum operating ceiling of a typical jet?
What is the maximum operating ceiling of a typical jet?
41.000ft
What is the center of pressure?
What is the center of pressure?
An aerofoil when placed in a flow will (normally) cause said flow to accelerate over the aerofoil and decelerate below it.
This will cause a pressure differential between the upper and lower surface of the aerofoil, and the resultant force will be applied at the center of pressure.
What systems protect against a stall?
What systems protect against a stall?
Stall warning, stick shaker, stick pusher, etc...
Generically we can destinguish between systems that alert the pilot of the impeding stall, like stall the stall warning or stick shaker, and systems that try to correct the situation, like a stick pusher.
Tell us what ranges the glideslope and localiser beams are checked out to?
Tell us what ranges the glideslope and localiser beams are checked out to?
Glideslope: 329.15-335Mhz UHF 8 degrees either side, 10NM
Localiser: 108.10-111.95Mhz VHF 35 degrees either side, 17NM
What is Vmu?
What is Vmu?
Vmu is the minimum unstick speed.
It is the calibrated airspeed at and above which the airplane can safely lift off the ground and continue the takeoff. Lift-off is not possible prior to reaching this speed.
Vmu is not an operational speed and is established in flight testing only.
You are at the end of the runway with the static ports blocked. What will be the reading on the altimeter after departure?
You are at the end of the runway with the static ports blocked. What will be the reading on the altimeter after departure?
The elevation at which the airplane departed from the runway.
