ACS element text (the applicant demonstrates understanding of)

When to declare minimum fuel or a fuel-related emergency.

Bottom line

Low fuel is treated as an in-flight emergency, and with most in-flight emergencies such as low fuel, the pilot should land as soon as possible. Declare any emergency on the last assigned ATC frequency; if one was not issued, transmit on the emergency frequency 121.5. Set the transponder to the emergency squawk code 7700, which triggers an alarm or special indicator in radar facilities.
