What is Mcrit?
What is Mcrit?
Mcrit is the aircraft’s Mach speed at which the airflow over a wing becomes sonic.
Describe the lift-weight pitching moments.
Describe the lift-weight pitching moments.
The weight of an aircraft is applied at the CG. The lift at the CP. The relative position between these 2 points determines the stability of the aircraft. For an Aircraft with a tail surface, a CG in front of the CP constitutes a stable system, while a CG behind the CP an unstable system.
Which way do jet streams travel?
Which way do jet streams travel?
From West to East
East to West (In Africa during the summer)
What are fusible plugs, where are they used, how do they work, why do we have them?
What are fusible plugs, where are they used, how do they work, why do we have them?
Fusible plugs offer protection from tire blowouts caused by thermal expansion that is generated in the tire under extra hard braking conditions.
How does GPWS work?
How does GPWS work?
GPWS is a central computer system that receives various data inputs on configuration, (radio altimeter) height/altitude and instrument landing system glide slope deviation and is able to alert the pilot when a dangerous situation is about to occur.
What setting would you set the trim to for long range cruise?
What setting would you set the trim to for long range cruise?
Nose up
What effect does a wet runway have on V1?
What effect does a wet runway have on V1?
V1 is lower when the runway is wet than when the runway is dry, because of the longer ASDR on a wet runway.
While climbing with a SEP, in what temperature range can carb icing occur?
While climbing with a SEP, in what temperature range can carb icing occur?
Carb icing can occur with temperatures as high 30°C and humidity as low as 50%, but it is more likely when below 20°C and high humidity, especially during low power settings.
Does a jet have a critical engine? Why yes or no?
Does a jet have a critical engine? Why yes or no?
No, there is no P-factor (asymmetric blade effect) as on a propeller-driven aircraft.
Some wings, flaps and rudders are indented, why?
Some wings, flaps and rudders are indented, why?
To increase the strength of the surfaces.
The same strategy is employed by plastic water bottles, by adding ridges to a surface you increase it's structural rigidity
