Occluded fronts are formed during the process of cyclogenesis when a cold front overtakes a warm front. When this occurs, the warm air is separated (occluded) from the cyclone center at the Earth's surface.

Occluded fronts usually form around mature low pressure areas.

Non Directional Beacon, a medium range radio navigation aid that sends out a signal in all directions for an aircraft to home to.

Average range over land 20 - 25 miles.

Range for an NDB can be calculated with:

2√power output in Watts = Range (Land) 3√ power output in Watts = Range (Water)

Angle of attack is the angle between the chord of the aerofoil and the relative airflow.

Angle of incidence is the angle between the chord and the aircrafts longitudinal datum.

OM = DOM + crew and fuel

The track changes constantly.

Always make sure to update yourself with the latest information on these type of questions.

CFM56-7 series with a max takeoff thrust of 27,300lb.

These engines have higher thrust, improved efficiency, and lower maintenance costs than its predecessor, the CFM56-3 series.

180 minutes extended range (ETOPS).

Bypass ratio 5.5:1

Stall speed is defined as the minimum steady flight speed at which the airplane is controllable.

Radiation fog forms on cloudless nights with only very light winds and high relative humidity when the cold ground cools the air above it to its dew point causing condensation (fog).

Usually occurs inland in valleys and low lying areas (as these areas tend to have more moisture) and usually occurs in a high pressure system.

For every 1kg of air passing through the combustion chamber, 11kg of air pass bypass the combustion chamber.
