1. Hi guys/gals... did refuelling the other day with PTF and upon finishing the bowser told us to release some pressure from the refuelling valves as it is not safe to disconnect the receptacles. The pressure can be seen on a gauge on the bowser truck. The technician then switched on the "ALL VALVES PRESELECT CONTROL" to closed position and preselect switch to "TOTAL" on P42 to ensure that the individual valves can be manually opened to release the pressure. Under certain circumstances, if the pressure is still not released, you need to go to the cockpit to trip some CBs on the automatic control of the valves and release the pressure on the individual valves again. Ensure that the pressure of the valves indicated on the truck has been released prior to disconnecting the refuelling receptacles.

2. Dispatch Authorisation (DA) can, under certain circumstances although rarely, be dispatched from Singapore provided concurrence be obtained from CAAS before DA is issued.
