Multiple Choice

Which mode I squawk means desire aircraft to assist?

In Mode I, transponder codes carry specific meanings about what you want or need from others monitoring radar. The group of codes in the 70s is reserved for assistance-related messages, and the particular code that explicitly signals a desire for help is the one you’d use when you want another aircraft or ATC to assist you. That explicit intent is why this option is the best choice. The other codes in that same range are used for different statuses or purposes, so they don’t communicate the explicit request for assistance.
