What is a jet stream?
What is a jet stream?
Jet streams are narrow bands of high-speed upper thermal winds at very high altitudes.
What is an MCP and what is an FMA?
What is an MCP and what is an FMA?
The mode control panel is used to select the autothrottle, autopilot, and flight director operating modes. The flight mode annunciator displays current flight modes.
What do you know about carb icing? Would you experience it today?
What do you know about carb icing? Would you experience it today?
Carb icing can occur in the engine induction system and in the carburettor of piston engines.
Regarding the second question, mention the conditions in which carb icing can occur and if it would be possible on that particular day.
Conditions for carb icing: when OAT is between -10 & +30, with high humidity (greater than 40%) and/or visible moisture.
How does an IRS work?
How does an IRS work?
An IRS is an Inertial Reference System which consists of accelerometers, gyroscopes (laser) and a position computer.
The computer calculates the aircrafts position by direction and velocity sensed by the accelerometers from the initial latitude and longitude input.
An IRS enables the aircraft to fly great circle tracks and to navigate accurately across vast expanses where no ground based navigation aids are available.
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 windshear?
What is windshear?
Windshear is a change of wind speed and/or direction from place to place, including updraughts and down draughts.
It is ussualy characterized by a strong change over a short distance. Windshear can effect the flight path and airspeed and can be hazardous.
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
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.
Would you be happy if VMCG is higher than V1?
Would you be happy if VMCG is higher than V1?
No, because if your critical engine fails at V1 you have to continue your takeoff roll, but because you’re under VMCG you are unable to maintain directional control.
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.
