Weight savings when removing galley components
Deletion of galley components is achieved through the application of the appropriate galley vendor service bulletin. Galley components may also be removed temporarily once approval from the galley manufacturer and the local aviation authority has been granted.
3.2.5.4.3. Safety Equipment
Safety equipment requirements are agreed between the aircraft operator and the local aviation authority. Typically, aircraft that are to be employed in over-water operations will be equipped with emergency slide rafts. However, for overland routes it may be possible to justify swapping slide rafts for basic slides.
Component Component Weight Total weight saving converting slides (4 per aircraft) from slide raft to basic slide = 128 Kgs
Slide Raft 57 Kgs
Basic Slide 25 Kgs
Note: over-wing exits are equipped with basic slides only.
This initiative will bring fuel cost savings of around US$4,600 to US$8,500 per aircraft per year (varies with utilization and based on fuel at US$2.00 per US Gallon).
3.2.5.4.4. Potable water upload reduction
Aircraft of the A320 Family are equipped with a potable water tank that can hold up to 200 liters, i.e. 200 kgs. The tank is refilled via the servicing panel at lower left-hand side of the rear fuselage and tank contents are indicated on a gauge on the servicing panel and on the Forward Attendants Panel (FAP).
Some aircraft are equipped with a system that allows the tank to be refilled to a pre-selected level (25%, 50% or 75% full, i.e. 50, 100 and 150 liters). For aircraft not equipped with the pre-selection system a simple alternative can be developed if the flow rate of the refill system is known (e.g. if the refill rate is 10 liters every 20 seconds, and 50 liters is required, then a “100 second replenishment” will be needed).
