What is the mean chord line?
What is the mean chord line?
It's the wing area divided by the wing span.
How does anti-skid work?
How does anti-skid work?
Antiskid has a detection system that senses the moment a wheel stops rotating.
Once it senses that the wheel is not rotating, the antiskid system releases brake pressure. This allows the wheel to regain traction with the surface, so that break application can be resumed and prevents complete loss of controllability.
What are the hydraulic systems of the Boeing 737 called?
What are the hydraulic systems of the Boeing 737 called?
Hydraulic system A and hydraulic system B.
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.
How does the all moving stabilator work on the Boeing 737 compared a fixed horizontal stabilizer of, for example, the Seneca?
How does the all moving stabilator work on the Boeing 737 compared a fixed horizontal stabilizer of, for example, the Seneca?
A moving stabilator allows for wider operating range of the control surface, which is of great importance in aircraft with a large range of operating speeds.
Compared to a fixed horizontal stabilizer, when trimmed, the moving stabilitor will produce less drag, reducing fuel consumption.
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.
How does TCAS work?
How does TCAS work?
TCAS works by sending interrogations to other aircraft's transponders.
The transponder will reply to the interrogation in a similar way it responds to radar. From the time difference between the interrogation and the reply, the distance to the other aircraft is calculated. The reply itself contains the altitude of the other aircraft.
The distance and the altitude difference with the other aircraft is tracked to identify a trend which may result in a TA or eventually a RA.
