Many moons ago, a new-hire pilot told me about a flight he had on his most recent shift. This flight was outside of our normal local operating area, and would certainly involve a fuel stop for the return with our normal fuel loadout. After giving me the general details of the flight, he told me that the low fuel warning light illuminated on short approach into the primary destination: a rooftop helipad in a major city. After shutting down and dropping off the passengers, he elected to start up and depart the pad to the nearest fuel source: a towered airport approximately seven minutes away by air. That’s right: he departed with the low fuel warning light still illuminated.
