Question

Assign a code of ____ when aircraft are operating on a flight plan specifying frequent or rapid changes in assigned altitude

A) 1200
B) 7500
C) 7600
D) 7700

Answer 1

The appropriate transponder code for a flight with frequent altitude changes is assigned by ATC and is not one of the standardized codes listed in the options.

Step-by-step explanation:

The code you would assign when aircraft are operating on a flight plan specifying frequent or rapid changes in assigned altitude is none of the listed options (A) 1200, (B) 7500, (C) 7600, (D) 7700. These codes are associated with transponder signals that are used for different purposes; 1200 is used for Visual Flight Rules (VFR) flying without ATC assignment, 7500 indicates a hijacking, 7600 represents a communications failure, and 7700 signifies a general emergency. For an aircraft with a flight plan that includes frequent altitude changes, the transponder code would typically be assigned by Air Traffic Control (ATC), and it would be unique to that flight and controlled airspace requirements.
