Match each altimeter setting in List I with what it references in List II.

List I

A. QNH

B. QFE

C. QNE

D. Radio altimeter

List II

1. Mean sea level

2. Aerodrome level

3. The standard 1013.25 datum

4. The terrain directly beneath the aircraft

Select the correct match.

  • A.A-1, B-2, C-3, D-4
  • B.A-2, B-1, C-3, D-4
  • C.A-1, B-3, C-2, D-4
  • D.A-3, B-2, C-1, D-4

Answer: A

Correct answer: A-1, B-2, C-3, D-4

Four references, three barometric and one not. QNH is set so the altimeter reads height above mean sea level, QFE so it reads zero on the aerodrome, and QNE is the standard 1013.25 datum used above the transition altitude. The radio altimeter is not barometric at all: it measures the actual distance to the terrain directly beneath the aircraft.
