What are the applicable maximum speeds for aircraft categories A through E on an ICAO turning departure?

The maximum speeds for aircraft categories A through E on an ICAO turning departure are specifically delineated based on the characteristics of each category, particularly their approach and landing speeds, which are established by the International Civil Aviation Organization (ICAO) guidelines. The correct choice provides these maximum speeds as follows: 120 knots for Category A, 165 knots for Category B, 265 knots for Category C, 290 knots for Category D, and 300 knots for Category E.

These speed limits are established to ensure safe separation between different category aircraft and to facilitate efficient traffic flow in the terminal area. By adhering to these prescribed speeds, pilots can safely conduct turns and maintain controlled flight while managing the aircraft’s performance within the specific capabilities of each category. Speed control during departures is critical, especially during turning maneuvers, to prevent conflicts with other aircraft and ensure compliance with air traffic control instructions.
