Which of the following aircraft is classified as Category F?

• A. B752
• B. CRJ9
• C. DH8D
• D. GLF4

Answer: (C)

The category classification of aircraft is determined by their approach speed, with different categories assigned to help air traffic controllers manage spacing and safety during takeoff, landing, and taxiing operations. Category F includes large aircraft with a specified approach speed range.

The DH8D, which is the Bombardier Q400, falls under Category F due to its maximum takeoff weight and operational characteristics that match the category's defined criteria. This aircraft typically has a higher approach speed compared to smaller general aviation planes, which is a key factor in its classification.

On the other hand, the other aircraft listed, such as the B752 (Boeing 757-200), CRJ9 (Bombardier CRJ900), and GLF4 (Gulfstream IV), do not meet the specific requirements set out for Category F due to their different designs and operational speeds. Their classifications are based on a range of technical specifications, including size, weight, and aerodynamic performance, which place them into different categories altogether.
