What is the mean camberine?
What is the mean camberine?
a line extending from the leading edge to the trailing edge equidistent from the upper and lower surface of the aerofoil.
What does a bypass ratio of 11:1 mean?
What does a bypass ratio of 11:1 mean?
For every 1kg of air passing through the combustion chamber, 11kg of air pass bypass the combustion chamber.
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 wings does the Boeing 737-800 use?
What wings does the Boeing 737-800 use?
Swept back wings
Where does the wing stall first on a typical SEP Aircraft (Cessna, Tecnam, ...)?
Where does the wing stall first on a typical SEP Aircraft (Cessna, Tecnam, ...)?
At the wing root. This is a property of rectangular wings, but it's also common to find close to the wing root devices that make it so that the wing root stalls first.
How much thrust comes from the N1 fan?
How much thrust comes from the N1 fan?
Depends on the engine.
In the case of the 737-800 CFM56, 27,300lbs total thrust at a ratio of 5.5:1
Why do we use Jeppesen charts/plates?
Why do we use Jeppesen charts/plates?
Jeppesen charts and plates are simplified and uniform.
Explain the definition “critical engine”.
Explain the definition “critical engine”.
The critical engine of a multi-engine, fixed-wing propeller-driven aircraft is the one whose failure would result in the most adverse effects on the aircraft's handling and performance.
Due to the asymmetric blade effect (P-factor), the right-hand engine typically develops its resultant thrust vector at a greater lateral distance from the aircraft's C.G. than the left-hand engine.
The failure of the left-hand engine will result in a larger yaw effect via the operating right-hand engine, rather than vice-versa, and it is termed the Critical Engine. Since the operating right-hand engine produces a stronger yaw moment, the pilot will need to use larger control deflections in order to maintain aircraft control. Thus, the failure of the critical (left-hand) engine is less desirable than failure of the right-hand engine.
The operating right-hand engine will produce a more severe yaw towards the dead engine, thus making the failure of the left-hand engine critical.
Why does the speed tape on the PFD reads 45kt when the aircraft is stationary?
Why does the speed tape on the PFD reads 45kt when the aircraft is stationary?
The speed is too low for an indication.
