PAQB

Question 1

Altitude

Answer 1

Vertical distance of a level, point, or an object considered as a point measured from a pressure elevation level

Question 2

Height

Answer 2

Vertical distance of a level, a point, or an object considered as a point measured from a specified datum.

Question 3

Elevation

Answer 3

vertical distance of a level or a point on or affixed to the surface of the earth measured from mean sea level

Question 4

Flight Level

Answer 4

Surface of a constant atmospheric pressure measured from a standard pressure datum of 1013.2 HPa or 29.92 inches of Hg.

Question 5

Transition Level

Answer 5

The lowest flight level available for use above the transition altitude. It varies with the QNH value of the aerodrome of area concerned.

Question 6

Transition Layer

Answer 6

The airspace between transition altitude and the transition layer.

Question 7

Minimum Descent Altitude (MDA)

Answer 7

The lowest altitude to which descent is authorized during non precision approach if visual contact is not established where no electronic glideslope is provided. The minimum descent altitude is indicated by pressure altimeter when set to QNH.

Question 8

Decision Altitude

Answer 8

the specified altitude (height) in the precision approach and precision like approach [RNAV (GPS)] at which a go around must be initiated if the required visual reference to continue the approach has not been established.

Question 9

Transition Altitude

Answer 9

the altitude in the vicinity of aerodrome(s) at or below w/c the vertical position of an aircraft is express in altitude that is determined from an altimeter set to sea level pressure (QNH).

Question 10

DA

Answer 10

is referenced to mean sea level.

Question 11

Decision Height

Answer 11

is referenced to threshold or touchdown zone elevation

Question 11

Waypoint

Answer 11

is a predetermined geographical position defined in terms of latitude/longitude coordinates; may be a simple name point in space or associated with existing navigational aids, intersection or fixes.

Question 11

Area Navigation System (RNAV)

Answer 11

area navigation, is a method of navigation that permits aircraft operation on any desired flight path within the coverage of station-referenced navigational aids (VOR, NDB) or within the capability of the aircraft’s self-contained aids (IRS, ADIRS, GPS) or combination of both.

Question 12

QNH

Answer 12

is the pressure value at sea level, if this value is set on the subscale, the altimeter will indicate the airfield elevation after landing.

Question 13

QFE

Answer 13

is the pressure value at aerodrome level, if the value is set on the subscale, the altimeter will zero after landing.

Question 14

QNE

Answer 14

(1013.2 Hpa/29.92 inHg) is the pressure value of standard atmosphere, is set on the subscale to indicate flight level above the transition level, to establish vertical separation of enroute traffic.

Question 15

CAVOK

Answer 15

ceiling, no weather and visibility ok, no clouds below 4,500’, no precipitation or thunderstorm and visibility 10km or more

Question 16

Temperature Inversion

Answer 16

a meteorological phenomenon where in the temperature increases as altitude increases; it deviates from the standard rule that the temperature decreases as the altitude increases.

Question 17

Standard Lapse Rate

Answer 17

temperature decreases 2 degrees centigrade per 1,000’

Question 18

Visibility

Answer 18

the maximum distance towards the horizon at which the meteorological observer can identify a prominent object or visual signal.

Question 19

Ceiling

Answer 19

the height of lowest observed opaque layer of obscuring phenomena aloft covering 4/8 or more of the sky and taken above the official aerodrome.
