What do high lift devices do?
What do high lift devices do?
High lift devices increase the lift produced by a wing, allowing the aircraft to operate at lower speed ranges usually for take off and landing.
What is DA?
What is DA?
Decision altitude (precision), the altitude at which a decision must be made during an ILS, MLS, or PAR instrument approach to either continue the approach or to execute a missed approach.
What is the washout on a wing?
What is the washout on a wing?
A wing design feature where the angle of incidence of the wing decreases from the root to the tip.
This makes it so that the wing as a tendency to stall at the root first, maintaining aileron control for a longer time and providing a resistence to spinning, facilitating recovery.
What are the effects on the human body in case of depressurisation?
What are the effects on the human body in case of depressurisation?
Hypoxia, a lack of oxygen to tissues of the body due to low partial pressure at altitude.
Symptoms are: blue lips, apparent personality change, impaired judgement, muscular impairment, short term memory loss, sensory loss, hyperventilation, unconsciousness.
Other possible effects:
-
Baurotrauma
-
Lung damage
What is drag?
What is drag?
Drag is the component of the total aerodynamic force parallel to the relative airflow.
Drag is generated by any body placed in a flow and it's composed of friction, form, and pressure drag.
What do you prefer, a high or low wingload?
What do you prefer, a high or low wingload?
The assessor was trying to get to the approach where you need flaps and slats to increase S (lower wingload) in order to be able to fly a lower speed.
What errors would cause an altimeter to malfunction?
What errors would cause an altimeter to malfunction?
Altimeter errors:
Instrument error Pressure error Time-lag error Barometric error
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.
What is EGPWS?
What is EGPWS?
Enhanced Ground Proximity Warning System, provides a greater level of detection than GPWS.
EGPWS is capable of ‘looking ahead’ to identify potential risks on the aircraft flight path as it includes a terrain and obstacle database.
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.
