Basic Empty Mass (BEM) is the mass of the aircraft with the basic equipment, unconsumable fluids and unusable fuel and oil.

Fusible plugs offer protection from tire blowouts caused by thermal expansion that is generated in the tire under extra hard braking conditions.

The assessor was trying to get to the approach where you need flaps and slats to increase S (lower wingload) in order to be able to fly a lower speed.

Transmitting uses more power.

They provide at least 1000ft clearance over obstacles within 25NM of the homing facility.

A free turbine is a turbine that is not directly connected to the compressor. This allows the compressor to rotate at a different speed than the turbine. Since the turbine speed is coupled with the propeller, this allows for the propeller to be maintained at a constant ideal speed.

Another advantage is that free turbine engines can be designed to be more compact than their single shaft counterparts

Advection fog occurs when moist air passes over a cool surface by advection (wind) and is cooled.

It is common as a warm front passes over an area with significant snowpack, but it is most common at sea when tropical air encounters cooler waters, including areas of cold water upwelling, such as along the coast of California.

Center of pressure moves forward when approaching a stall.

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

Yes, with the modern high bypass turbofans the N1 compressor works as a huge propeller, it takes a big mass of air and gives it a relative small acceleration.

Around 70% of the air will bypass the core of the engine, only 30% of air will be compressed further and will eventually go through the combustion chamber.
