What is the critical point?
What is the critical point?
The critical point (CP) is a point on a track where it is as quick to go on as it is to turn back.
Also known as ETP (Equal Time Point) and PET (Point of Equal Time).
Is the landing gear in the Seneca electrically or hydraulically operated?
Is the landing gear in the Seneca electrically or hydraulically operated?
We are missing the answer.
If you are flying your light twin, how would you ensure minimum obstacle clearance if your engine fails on take off? How would you do this, or, where can you find the relevant information?
If you are flying your light twin, how would you ensure minimum obstacle clearance if your engine fails on take off? How would you do this, or, where can you find the relevant information?
In the airplane documents, as the airplane is certificated regarding performance to be able to fly blue line speed (or Vyse) in this situation, so I would climb at this speed to ensure minimum obstacle clearance.
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 sort of weather would you find at an occluded front?
What sort of weather would you find at an occluded front?
Low pressure weather, unstable weather.
Why does a wing stall?
Why does a wing stall?
A wing stalls because the airflow over the wing’s upper surface separates when the critical angle of attack is reached or exceeded. This causes a reduction in the lift generated by the aerofoil
Can you go through DA or MDA?
Can you go through DA or MDA?
You can go through a DA, but not a MDA.
A Decision Height, used in precision approaches, defines the point where a go around should be performed. It accounts for the altitude loss during the initial seconds of the go around maneuver.
The MDA does not account for this and assumes the pilot will never go below this altitude. When performing a CDFA most operators establish a Derived Decision altitude (DDA) to account for the extra lost altitude.
How does an IRS work?
How does an IRS work?
An IRS is an Inertial Reference System which consists of accelerometers, gyroscopes (laser) and a position computer.
The computer calculates the aircrafts position by direction and velocity sensed by the accelerometers from the initial latitude and longitude input.
An IRS enables the aircraft to fly great circle tracks and to navigate accurately across vast expanses where no ground based navigation aids are available.
Why do we measure speed as a Mach number?
Why do we measure speed as a Mach number?
Mach number describes the speed of sound, which changes with the density of the medium it is travelling through.
When you reach the speed of sound, the compressibility effect creates a supersonic flow along the wing if you exceed a certain mach number.
This causes airflow separation and flutter.
It is therefore much safer and much easier to use a Mach number to express a limit at which compressibility effects start to tear the aircraft apart, as it is a constant value at all altitudes.
