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.
How would you explain to your neighbour what the difference is between a precision and a non-precision approach?
How would you explain to your neighbour what the difference is between a precision and a non-precision approach?
A precision approach uses both lateral (from left to right) and vertical guidance. A non-precision approach only uses lateral guidance.
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.
What pressure does a pitot tube measure?
What pressure does a pitot tube measure?
The total pressure (static and dynamic pressure).
What wings does the Boeing 737-800 use?
What wings does the Boeing 737-800 use?
Swept back wings
What is the difference between angle of attack and angle of incidence?
What is the difference between angle of attack and angle of incidence?
Angle of attack is the angle between the chord of the aerofoil and the relative airflow.
Angle of incidence is the angle between the chord and the aircrafts longitudinal datum.
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
The tailplane of a Seneca has an elevator and a trim tab, what does a Boeing 737 have?
The tailplane of a Seneca has an elevator and a trim tab, what does a Boeing 737 have?
The Boeing 737 has an all moving horizontal stabilizer.
Why do we use Jeppesen charts/plates?
Why do we use Jeppesen charts/plates?
Jeppesen charts and plates are simplified and uniform.
Can VMCG be lower than V1? Explain.
Can VMCG be lower than V1? Explain.
Yes, VMCG has to be equal to or less than V1 to ensure the aircraft could maintain runway heading having suffered an engine failure at or above V1 when the aircraft is committed to takeoff.
