You lose fuel indication during a flight, what is the best course of action?
  • A
    Open the cross-feed valve to make sure the aeroplane stays in balance.
  • B
    Pull and reset the circuit breakers to check if the system restarts, unless the checklist says otherwise.
  • C
    Land as soon as possible and prepare for power off landing.
  • D
    Turn off fuel pumps for 10 min and then turn them back on hoping fuel indications come back.

LO 021.09.01.07.04 : Describe how circuit breakers may be used to reset aircraft systems/computers in the event of system failure (when part of a described procedure).

Pulling and resetting the circuit breakers are usually the first items on the checklist on such an occasion. Unless otherwise advised, it should be the first thing to do. This avoids a potentially costly diversion for the case of a simple electronic fault.

Of course, it is important to continually monitor the fuel level and corresponding indications. If this was a fuel leak (which is the worst case scenario), it would be important to fly to the nearest suitable airport and land immediately, however, this will probably be an early part of the checklist if a fuel leak/fault is diagnosed/expected.
