2 questions for the pros
![Wink ;)](./images/smilies/icon_e_wink.gif)
:
How many liters of water necessary for the toilets and for pax minimum comfort for such a flight?
How many liters of bottled water, sodas, juices, wine, alcohol were on board? What's their total cost vs the cost of returning to London and cancelling the flight?
Disclaimer : I'm not a pro in sh!t business
From the respective APMs, the so called "Potable Water" capacities :
A332/3/8/9 : 700 litres, 1050 L option.
A388 : 1700 L (six-tank std), 1998 L (7-tank option), 2267 L (8-tank option).
Originally EK took more due to the showers but I think they reduced the total uplift.
Potable water is used for the galleys and toilets (wash basin).
Only a very small amount of water is used to flush the toilet, if any, and I think it is then mixed with the “blue juice”, the chemical precharge. (36-54 L for the A330, on the A388 each of the 4 tanks is precharged with 35 L).
Toilets are flushed by vacuum and the non-stick coating of the bowl requires a very small amount of liquid (0.2 L ?) to flush ... what needs to.
On short haul the uplift will be limited, e.g. 100 L, to avoid carrying deadweight but I doubt long haul will take less than full tanks.
You can check the amount in water and waste tanks on the Panel at the forward FA station.
A pic I took on an Air Asia between KL and PKU. At first the FA did not oppose my request but they kept coming back during the flight asking the why's and whatfor's.
