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 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 is profile drag?

What is profile drag?

Profile drag, also known as pressure drag or form drag, is the drag caused by the separation of the boundary layer from a surface and the wake created by that separation.

It is primarily dependent upon the shape of the object and increases directly with speed as the faster an aircraft moves the more air molecules collide with it.

Why do you need contingency fuel?

Why do you need contingency fuel?

Contingency fuel is carried to account for additional enroute fuel consumption caused by wind, routing changes or ATM: ATM/CNS restrictions.

What is an MCP and what is an FMA?

What is an MCP and what is an FMA?

The mode control panel is used to select the autothrottle, autopilot, and flight director operating modes. The flight mode annunciator displays current flight modes.

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.

Explain V1, V2, VR, VMCA and VMCG

Explain V1, V2, VR, VMCA and VMCG

V1 is the decision speed (sometimes referred to as critical engine speed or critical engine failure speed) by which any decision to reject a takeoff must be made.

V2 is the takeoff safety speed which must be attained at the 35 ft height at the end of the required runway distance. This is essentially the best one-engine inoperative angle of climb speed for the airplane and is a minimum speed for flight in that condition until at least 400 ft above the ground. V2 shall be at least 1.1 times VMCA, and no less than 1.2 times VS.

Vr is defined as the speed at which the rotation of the aircraft should be initiated to takeoff attitude.

VMCA is the minimum control speed in the air and is defined as the minimum speed, whilst in the air, that directional control can be maintained with one engine inoperative (critical engine on two engine aerolanes), operating engine(s) at takeoff power and a maximum of 5 degrees of bank towards the good engine(s).

VMCG is the minimum control speed on the ground and is defined as the minimum speed, whilst on the ground, that directional control can be maintained, using only aerodynamic controls, with one engine inoperative (critical engine on two engine airplanes) and takeoff power applied on the other engine(s).

What are winglets and what is the advantage of winglets?

What are winglets and what is the advantage of winglets?

They are aerodynamically efficient surfaces located at the wing tips, designed to reduce induced drag and increase fuel efficiency.

They increase efficiency by reducing the size of the wingtip vortices, which are created by the difference between the pressure on the upper surface of the wing and that on the lower surface.
