Question 1

Under which conditions "back side weather" ("Rückseitenwetter") can be expected?

Accepted Answer

After passing of a cold front

Answer

Before passing of an occlusion

Answer

During Foehn at the lee side

Answer

After passing of a warm front

Question 2

The "spread" is defined as...

Accepted Answer

Difference between actual temperature and dew point.

Answer

Difference between dew point and condensation point.

Answer

Relation of actual to maximum possible humidity of air

Answer

Maximum amount of water vapour that can be contained in air.

Question 3

The gliding weather report states environmental instability. In the morning, dew covers grass and no thermals are presently active. What development can be expected for thermal activity?

Accepted Answer

With ongoing insolation and ground warming, thermal lifting is likely to begin

Answer

Formation of dew prevents all thermal activity during the following day

Answer

Environmental instability prevents air from being lifted and no thermals will be generated

Answer

After sunset and formation of a ground-level inversion thermal activity is likely to begin

Question 4

Accepted Answer

Surface overheat and damage to exposed aircraft parts

Answer

Explosion of electrical equipment in the cockpit

Answer

Question 7

Light turbulence always has to be expected...

Accepted Answer

Below cumulus clouds due to thermal convection.

Answer

Above cumulus clouds due to thermal convection.

Answer

Question 9

Which process may result in an inversion layer at about 5000 ft (1500 m) height?

Accepted Answer

Widespread descending air within a high pressure area

Answer

Ground cooling by radiation during the night

Answer

Intensive sunlight insolation during a warm summer day

Answer

Advection of cool air in the upper troposphere

Question 10

While planning a 500 km triangle flight, there is a squall line 100 km west of the departure airfield, extending from north to south, moving east. Concerning the weather situation, what decision would be recommendable?

Accepted Answer

To postpone the flight to another day

Answer

To change plans and start the triangle heading east

Answer
