An aircraft is flying over the sea at FL120, with a true altitude of 12 000 feet, local QNH is 1013 hPa. What assumption, if any, can be made about the air mass in which the aircraft is flying?
Warmer than ISA
Same temperature as ISA
Colder than ISA
Insufficient information
The crew is planning a flight across Himalayas at FL390. The QNH at the station located at 5 000 ft is 1 013 hPa. The forecasted temperature at FL390 is -48°C. What would be the clearance above the peak of 29 029 ft.
11875 ft
8871 ft
11127 ft
11297 ft
A vertical spacing of 1 000 ft, is the standard required separation between two FL. Under conditions of cold air advection (ISA -15 °C), what would the true vertical separation be?
Less than 1000 ft.
More than 1000 ft.
It remains 1000 ft.
Cannot be determined.
An aircraft flying at FL100 from Marseille (QNH 1012 hPa) to Palma de Mallorca (QNH 1006 hPa) experiences no change to true altitude. The reason for this is that:
the air at Palma de Mallorca is colder than that at Marseille.
the air at Palma de Mallorca is warmer than that at Marseille.
the altimeters are unservicable, and need to be tested.
one of the two QNH values may be incorrect.

Why is a calm and clear-sky night cooler than a cloudy night?
The clouds prevent radiation from the atmosphere.
There is radiation from the clouds.
Due to contents of carbon dioxide.
The radiation from the Earth's surface slips into space.
Aerodrome elevation is 429 ft. QFE is 992 hPa, temperature is ISA +15°C at all altitudes. Calculate the QFF (assume 27 ft/hPa).
1009 hPa
1007 hPa
1012 hPa
1003 hPa
Over Caen Airport in France, the transition altitude is given as 13 000 feet and the transition level as FL150. If the QNH on the airfield is 1 003 hPa, what is the vertical extent of the transition layer? Assume 1 hPa = 40 feet.
2200 feet
890 feet
1600 feet
1400 feet
Which is true of the temperature at the tropopause?
It is higher in equatorial regions than in polar regions.
It is higher in polar regions than in equatorial regions.
There is no significant difference with change of latitude.
It is highest in middle latitudes.
What can be said about the temperature in the lower stratosphere?
Increasing
Constant
Decreasing
Increasing, then decreasing
Which figure represents the typical jet steam flow patterns in July?
Which forces are balanced with geostrophic winds?
Gravitational force, Pressure gradient force, Coriolis force.
Pressure gradient force, Centrifugal force, Friction force.
Pressure gradient force, Coriolis force, Centrifugal force.
Pressure gradient force, Coriolis force.
An aircraft is flying through the west east blowing polar front jet stream from south to north, beneath the core. How would the OAT change, in the northern hemisphere, during this portion of the flight?
It first increases, then decreases.
It remains constant.
It decreases.
It increases.
Under anticyclone conditions in the northern hemisphere, with curved isobars, the speed of the gradient wind is:
the same as the thermal component.
greater than the equivalent geostrophic wind.
proportional only to the Coriolis force.
less than the equivalent geostrophic wind.
In the northern hemisphere, during periods of prolonged cloudless skies over land, associated with anticyclonic conditions, the:
wind tends to back from early morning until early afternoon.
surface wind speed tends to be highest during the mid afternoon.
angle between isobars and surface wind direction tends to be greatest in the mid afternoon.
surface wind speed tends to be highest at night.
