3.2.5.3.9. Aircraft exterior cleaning
The natural accumulation of dirt on the aircraft’s external surface will introduce a slight roughness that, overall, can induce significant additional drag. There is no standard definition of how dirty is a “dirty aircraft” and so this assessment can only give an indication for the potential fuel penalty.

3.2.5.4. WEIGHT REDUCTION
A reduction of 100 kilograms of aircraft weight will save between 3 and 9 kilograms of fuel on a typical sector flown by an A320 Family aircraft. Over the course of a year this translates into a saving in fuel ranging from US$3,500 to in excess of US$6,500 (varies with utilization and based on fuel at US$2.00 per US Gallon).

condensation that may form wherever
SIL 21-051 – Cabin Water Condensation possible. Nonetheless, a recent study Point of Contact: nigel.dadswell@airbus.com has suggested that an aircraft of the A320 Family can accumulate and retain in excess of 200 kilograms of water.
