Aircraft approach category
A grouping of aircraft based on a speed of VRef, if specified, or if VRef is not specified, 1.3 x VS0 at the maximum certificated landing weight. VRef, VS0, and the maximum certificated landing weight are those values as established for the aircraft by the certification authority of the country of registry. An aircraft shall fit in only one category. If it is necessary to maneuver at speeds in excess of the upper limit of a speed range for a category, the minimums for the next higher category should be used. For example, an aircraft which falls in Category A, but is circling to land at a speed in excess of 91 knots, should use the approach Category B minimums when circling to land. The categories are as follows:
  • Category A: Speed less than 90 knots.
  • Category B: Between 91 and 120 knots.
  • Category C: Between 121 and 140 knots.
  • Category D: Between 141 knots and 165 knots.
  • Category E: Speed 166 knots or more.

AIRCRAFT APPROACH CATEGORY
A grouping of aircraft based on a speed of 1.3 times the stall speed in the landing configuration at maximum gross landing weight. An aircraft must fit in only one category. If it is necessary to maneuver at speeds in excess of the upper limit of a speed range for a category, the minimums for the category for that speed must be used. For example, an aircraft which falls in Category A, but is circling to land at a speed in excess of 91 knots, must use the approach Category?B minimums when circling to land. The categories are as follows:

a. Category A
Speed less than 91 knots.

b. Category B
Speed 91 knots or more but less than 121 knots.

c. Category C
Speed 121 knots or more but less than 141 knots.

d. Category D
Speed 141 knots or more but less than 166 knots.

e. Category E
Speed 166 knots or more.
(Refer to 14 CFR Part 97.)
