Which symbol indicates a nonstandard use of an aerospace vehicle, such as test, experimental, or prototype?

• A. Status Prefix Symbol
• B. Basic Mission Symbol
• C. MDS Symbol
• D. Modified Mission Symbol

Answer: (A)

Nonstandard use is shown by the status prefix symbol. This prefix flags a designation as experimental, test, or prototype rather than a standard production version, signaling its testing role. For example, X-15 uses the prefix to indicate its experimental status. The other symbols relate to standard missions, mission design series, or modifications, not to indicating nonstandard testing status.
