Airbus wet runway perf

[Phartiphukborlz]

Chaps,
Currently flying for and airbus operator who is providing only wet runway charts for alternate airfields.

The premise for this is that having conducted a 'dry check', then the wet charts are conservative and that they can then be used on a dry runway.

My reading of FCOM, CAO, and other documents is that this is not appropriate based on 15' screen heights etc

Would appreciate some adult comment on this.

Regards

Like you said, wet figures reduce the margin for the go case. You will have a lower V1 to account for a longer stop but on a dry runway you would normally stop up to a higher speed using dry numbers.

Have an engine fire at a wet V1 on a dry runway and you go flying on fire with reduced margins, if you were using the correct figures for a dry runway you would have plenty of time to stop.

Seems a bit stupid to me.

If you give me the specifics I will run the numbers through the PEP so we have a clear idea of exactly what we are dealing with :)

Have asked the question of the organization and dry charts are to be issue - resolved,

Thanks
