Due to the structural damage that may occur in thunderstorms, due to hail, severe turbulence and severe windshear.

Besides that, lightning strikes may cause damage to electrical systems and severe icing may occur.

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

Altimeter errors:

Instrument error Pressure error Time-lag error Barometric error

Drag penalties (additional weight)

Less controllability

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.

Carb icing can occur with temperatures as high 30°C and humidity as low as 50%, but it is more likely when below 20°C and high humidity, especially during low power settings.

Because the air is less dense thus the TAS is higher for a given power setting and for this reason modern jet aircraft are designed to be most efficient at high altitude.

A METAR is an observation of the actual weather given by a meteorological observer at that aerodrome.

Reduced Vertical Separation Minima (RVSM) is the reduction, from 2,000 feet to 1,000 feet, of the standard vertical separation required between aircraft flying between flight level 290 (29,000 ft) and flight level 410 (41,000 ft).

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.
