| 摘要 |
A fuel jettison system which provides pilot-initiated automatic operation to jettison fuel down to a 60 minute useable fuel remaining level while the manual operation, requiring the pilot to hold down the jettison panel switch, jettisons fuel down to a 20-minute useable fuel remaining level. The pilot can interrupt jettisoning at any time. This termination sequence operates in either automatic or manual mode. The port and starboard main fuel tanks jettison fuel independently through independent shutoff valves and associated circuit logic to thereby maintain aircraft balance.
