317 [Fig.16] When is advection fog most likely to form?

Wähle eine der folgenden:

O When warm, moist air moves across a cold land surface and is cooled below its dewpoint temperature.

319 You depart from aerodrome of Kastelorizo (LGKJ), (situated 474 feet above mean sea level (AMSL) with a QNH of 1011 hpa set on the altimeter subscale. The flight is conducted towards an area of low pressure and you fail to update the subscale setting (due to being non-radio). You anticipate a visual landing at the aero¬drome οf Kasteli(LGTL). What will the altimeter read when the aircraft lands at the destination aerodrome, which has an elevation of 1180 feet AMSL, if the QNH is 994 hpa?

Wähle eine der folgenden:

O 1690
O 1750
O 950
O 1197

Erklärung

Wähle eine der folgenden:

O pressure is low and temperature is high.
O pressure is low and temperature is low.
O pressure is high and temperature is high.
O pressure is high and temperature is low

Erklärung

321 A cumulonimbus with an anvil, signifies that the thunderstorm is in the:

Wähle eine der folgenden:

O decaying stage.
O cumulus stage.
O mature stage.
O none of those.

Erklärung

322 The force that causes a parcel of air to start moving from an area of high pressure to an area of low pressure is called the:

Wähle eine der folgenden:

323 If maritime air is heated from below, as it moves from its source region, it is likely to become:

Wähle eine der folgenden:

Erklärung

Frage 12 von 25

1

324 The rate of decrease of temperature in rising saturated air is less than for rising unsaturated air. Why is this the case?

Wähle eine der folgenden:

O Latent heat is released during the condensation process, and therefore warms the surrounding air, reducing the rate of temperature decrease.
O Saturated air rises more slowly, with a resultant decrease in the rate of cooling.
O Saturated air resists mixing with the cooler upper air.
O Saturated air is more dence
