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.
What will happen if the primer of your engine/fuel system kept operating?
What will happen if the primer of your engine/fuel system kept operating?
A variable pitch propeller provides an optimum angle of attack for the propeller blades for a longer range which reduces fuel usage, fixed pitch propellers only have a certain rpm.
Is carb heat an electrical system?
Is carb heat an electrical system?
No. Carburetor heat uses exhaust air to heat air going into the carburetor. No electrics are involved.
What is an anti-servo tab?
What is an anti-servo tab?
An anti-servo tab works in the opposite way to a servo tab.
It deploys in the same direction as the control surface, making the movement of the control surface more difficult and requires more force applied to the controls by the pilot.
What is the role of Pilot Monitoring?
What is the role of Pilot Monitoring?
To monitor the flight management and aircraft control actions of the Pilot Flying and carry out support duties such as communications and check-list reading.
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.
Tell me, I was looking out the window and I saw white strokes coming out of the engines at cruising level, but I didn’t see it from an aircraft taking off, why is that and what is the difference?

Those are contrails.
The jet engine exhaust gases consist of carbon dioxide and water vapour.
At high altitudes the wator vapour gets released in a very cold environment. This can cause the air to be saturated with water vapour and then condenses. If cold enough the condense can freeze into white droplets. This forms the contrails.
If the yaw damper fails and the aircraft experiences Dutch roll, how can the pilot stabilize the aircraft?
If the yaw damper fails and the aircraft experiences Dutch roll, how can the pilot stabilize the aircraft?
Apply opposite aileron to the direction of the roll.
What is the effect of weight on the glide range?
What is the effect of weight on the glide range?
The glide range is not affected by the weight. Howver Vmd is. The heavier the aircraft, the higher the Vmd.
How would you load an aircraft for max range?
How would you load an aircraft for max range?
The position of the CG directly influences the fuel consumption of an aircraft. An aft position of the CG makes the aircraft less stable, requiring less lift to be generated in both the horizontal stabilizer and wings, reducing the overall drag of the aircraft, and increasing the max range.
You want to load the the aircraft so that the CG is at, or as close as possible, to the aft limit (Without exceeding it).
