Airbus A320 Performance FCOM

Takeoff Parameters There is no maximum certified value for headwind, however a headwind higher than XXX results in no additional performance credit.

40 kt

How many Derate levels are available?

Six derate levels are available 

Is it permissible to combine Derate and flex?

It is not permitted to combine a derated takeoff and a FLEX takeoff.

TOGA Selection and Derate?

Not allowed unless above F speed

Takeoff performance is calculated XXXXX the benefit of thrust reversers

Without

A runway is considered as wet,

when the surface is covered by any visible moisture or water up to and including 3 mm (1/8 in) depth. When the water film does not exceed 3 mm (1/8 in), there is no significant danger of hydroplaning.

Takeoff performance on a wet runway can be calculated XXXX the benefit of thrust reversers.

with.. However, it is not allowed to take off at a weight higher than the weight on dry runway.

For runways that have portions declared as slippery wet, performance should be calculated with the Slippery wet runway condition option, or, if not available,

Dry snow 10 mm (2/5").

A runway is contaminated when more than 25 % of its surface is covered with:

A layer of fluid contaminant not considered as thin A hard contaminant.

In terms of performance, a contaminated runway is a runway covered by a hard contaminant that can be either:

Compacted snow Ice (Cold and Dry) Wet ice.

 fluid contamination is equivalent to wet, up to a maximum depth of 3 mm (1/8 in) of: 4 Contaminants, which?

Dry snow Wet snow Standing water Slush.

Is operation on Wet Ice permitted?

Yes

If the number of negligible CDL items is more than XXX a drag increase for each item is applied.

three,

The Cost index (CI) is defined as the ratio between

Cost of Time per time unit (CT) and Cost of Fuel per mass unit (CF).

The Long Range Cruise speed (LRC) is defined as the Mach number for which the specific range is equal to XXX of the maximum specific range.

99 %

Turbulence penetration speed?

260 up to FL200, 280 between FL200 and FL300. M0.76 from FL300

The optimum altitude (OPT ALT) is the altitude at which the

SR is maximum.

The recommended margin is a Factor of XXX on the In-Flight Landing Distance. In an emergency situation, the flight crew may decide to disregard this margin.

1.15

The go-around climb gradient must be at least equal to: for DA above 200ft

2.1%

EU-OPS requires a minimum go-around climb gradient of XXX for instrument approaches with decision heights below 200 ft.
