CAT III ILS approaches are classified by visibility minima. Which correctly describes CAT IIIb?
Answer: DH below 50 ft or no DH, RVR 150–700 ft
CAT IIIb allows operations with a DH of less than 50 ft (or no DH) and an RVR of 150 to 700 ft, requiring specialized aircraft equipment, crew training, and airport infrastructure.
During an ILS approach, the glide slope needle indicates 'fly up' (needle below center). The pilot should:
Answer: Reduce descent rate or level off momentarily to allow glide slope to come back up
When the glide slope needle shows 'fly up' (below center), the aircraft is below the glide slope — the pilot should reduce descent rate or level off to allow the aircraft to return to the glide slope.
What is the purpose of a Localizer-type Directional Aid (LDA) approach?
Answer: To provide localizer-style lateral guidance where the runway is not aligned with the approach course
An LDA provides localizer-type lateral guidance when the approach course is offset more than 3° from the runway alignment, often used at airports where terrain prevents a straight-in approach.
After passing the Final Approach Fix (FAF) on a non-precision approach, the pilot should:
Answer: Begin timing and descend to MDA without descending below it until the MAP
After the FAF on a non-precision approach, the pilot descends to the MDA, then flies level at the MDA until either the runway environment is in sight (continuing to land) or the MAP is reached (initiating missed approach).
A procedure turn is not required when an approach chart indicates:
Answer: 'NoPT' or the pilot is being radar vectored to the final approach course
A procedure turn is not required (and must not be made) when the chart indicates 'NoPT,' when the pilot is being radar vectored to the final approach course, or when flying a timed approach.
The Precision Approach Path Indicator (PAPI) provides visual glide path information using light color combinations. A correct 3° approach is indicated by:
Answer: Two red lights on the left and two white lights on the right
On a standard PAPI system, two red and two white lights (red on pilot's left, white on right) indicate the pilot is on the correct 3° glide path.
