Which of the following is one of the four types of flights?

• A. Numbered
• B. Named
• C. Gamma
• D. Alpha

Answer: (D)

In this framework, flights are categorized by fixed designations using the phonetic alphabet, with four standard names that identify different sections. Alpha is one of those four, typically representing the first flight or section. This makes it the best answer because it aligns with the established set of flight designations used in this context. Gamma isn’t part of the standard four, and using a numbered or named scheme doesn’t fit the conventional Alpha–Delta designations used for these flights.
