A pilot is planning a circling approach. The aircraft's stall speed in the landing configuration (Vso) at maximum certificated landing weight is 100 knots. Using the standard 1.3 x Vso method, what circling approach category applies to this aircraft?
- ACategory C
- BCategory B
- CCategory D
- DCategory A
Show answer & explanationAnswer & explanation
Correct answer: A. Category C
Circling approach category speed is computed as 1.3 x Vso: 1.3 x 100 = 130 knots. Category C covers approach speeds from 121 to 140 knots, so this aircraft falls into Category C.
Why the other options are wrong
- B. Category B is 91-120 knots; 130 knots exceeds this range.
- C. Category D begins at 141 knots, above the computed speed.
- D. Category A is under 91 knots, far below the computed 130 knots.
Circling Approach Categories
Aircraft are grouped into approach categories (A-E) based on 1.3 times the stall speed in landing configuration at max landing weight, determining circling minimums.
- Category A: <91 knots
- Category B: 91-120 knots
- Category C: 121-140 knots
- Category D: 141-165 knots
- Category E: 166 knots or more
