Which light indicates aft fuselage tank depletion?

Explanation:
Understanding how the fuel transfer system signals depletion in the aft fuselage tank is key. In the Beechjet 400A, fuel from the aft fuselage is moved to the wing tanks by a transfer pump, and the system watches the pressure in the transfer line. If the aft fuselage tank is depleted, there isn’t enough fuel to feed the transfer pump, and the pressure in that line falls. That drop triggers the transfer pressure low light, giving you a direct indication that the aft fuselage tank is running low or empty. Other indicators point to different issues: a low level light in a tank simply flags low fuel in that tank, not specifically depletion of the aft fuselage; a left wing tank overpressure light warns of excessive pressure in that wing tank; and a fuel pump fail light signals a pump malfunction rather than tank depletion. So the transfer pressure low indication is the best cue for aft fuselage depletion.
