Pregunta 5
Pregunta
317 [Fig.16] When is advection fog most likely to form?
Respuesta

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?

Pregunta 11
Pregunta
323 If maritime air is heated from below, as it moves from its source region, it is likely to become:
Pregunta 12
Pregunta
324 The rate of decrease of temperature in rising saturated air is less than for rising unsaturated air. Why is this the case?
Respuesta
-
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
