There’s three choices we have as ATC in a fuel emergency, on Infinite Flight. “Expect no delay”, “Expect delay” or in some cases we’ll tell you to divert to the nearest airport. If we tell you to “Expect no delay”, expect no delay, you’ll be brought in on the fastest route possible. Sometimes we even use the opposite end of active runways to get you down as quickly as possible.
“But what if I’m on a long haul?” The length of your flight has no meaning to us, we may not have time to check where you came from exactly so we apply equal treatment to anyone with a fuel emergency.
