RE: Toilet waste disposel in mid-flight
Hi all,
As we have gathered it does in certain circumstance happen that human excrement has been dumped as i have read the odd AAIB report on certain cases – but on the fuel dumping situation this is a regular occurance.
As has been sed an aircraft in an emergency has the facility to dump fuel, but in the main this is usually in a situation of urgancy – i.e. a PAN situation. The dumping of fuel may happen in such a situation as say an a/c on departure has had a birdstrike or lost a panel – the most efficient means of securing a safe onward journey maybee to bring the plane bak to it’s destination or another relevent airport – such as many of the UK charter airlines may return to Gatwick if a prob occurs after a departure from a northern uk field due to it’s excellent engineering facilities. In cases such as this where it is more a sake of conveniance over emergency the a/c could decided to reduce the risk of damage to itself and the runway (remember even an a/c the size of a fully laiden 767 could do a hell of a lot of damage to a runway if a heavy overweight landing was carried out, as well as a potential for damaging the a/c itself.
But as mentioned in the BA 744 down under not so long bak this risk is quite minimal in return to a MAYDAY situation where a serious risk to human life is involved – in the case of an in-flight fire the priority is to get that plane out of the sky and onto ground where the fire-fighting and medical facities are rather than circling around in mid-air with an ever increasing fire size risking all life aboard an below on the ground – i dont know if this has been pointed out but in certain emergerncy situations aircraft inbound to LHR are not allowed to fly over london so a teardrop pattern has to be flown – i.e if the a/c has taken off on 27R for example it will loop around to land bak on 09L to minimise the risk below it’s flightpath.
