Final Flashcards
A blue segmented circle on a sectional chart depicts which class airspace?
Class D
Normal VFR operations in Class D airspace with an operating control tower require the ceiling and visibility to be atleast -
1000ft 3sm
When may an ELT be tested?
During the first 5 minutes after the hour.
What affect does high density altitude have on aircraft performance.
It reduces climb performance
For aviation purposes, ceiling is defined as the height above the earths surface of the -
lowest broken or overcast layer, or vertical visibility into an obscuration
One of the most easily recognizable discontinuities across a front is -
A change in temperature
The boundary between two different air masses is referred to as a
front
What cloud type would indicate convective turbulence?
towering cumulus clouds
What are the processes by which moisture is added to unsaturated air?
Evaporation and sublimination
Clouds, fog, or dew will always form when -
relative humidity reaches 100 percent
The amount of water vapor which air can hold depends on the -
air temperature
What is meant by the term “dewpoint?”
The temperature to which air must be cooled to become saturated.
The wind at 5000’ AGL is southwesterly, while surface wind in southernly. This difference in direction is primarily due to -
friction between the wind and the surface
An airports rotating beacon operating during daylight hours indicates -
that weather at that airport located in Class D airspace is below basic VFR weather minimums.
During night flight, you observe a steady red light and flashing red light ahead and at the same altitude. What is the general direction of movement of the aircraft?
the other aircraft is crossing to the left.
