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.

Forward motion forces air into the intake which is a convergent duct where it is compressed (causing a temperature rise).

Fuel is added and combustion takes place increasing the volume. The expanding gasses accelerate to the atmosphere through the exhaust duct nozzle producing a propulsive jet.

Wingtip vortices are tubes of circulating air that are left behind a wing as it generates lift.

They are caused by the difference in pressure above and below the wing causing the air to 'escape' from the high pressure area below the wing to the low pressure area above the wing, by rolling around the tip of the wing. This creates a vortex that trails behind the wing.

At the tip as downwash and spanwise flow effect the angle of attack at each section, but because of the tapered wing the effective angle of attack near the tips is greater than that near the center.

Boots on the leading edges inflate (6 seconds) to break the ice dissipating it into the airflow.

Powered by the gyro pressure system.

Fuel injection provides:

• Fuel free from vaporization ice

• Better economy through metered delivery

• More responsive and efficient engine

• Less maintenance

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.

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