Landing distance calculation

[flyingdunky]

Hello guys,
I am striving to get a clear answer about Jar-ops 1.595 application, but I got in descending spiral about to understand if the a.m. rule applies only during the dispathing the flight or also on the operation of the same if for any reason (commercial, fuel, wx, tech but not emergency, etc) you have to divert to a non planned alternate along the route.
Anyone can drop a line for help?
Thanks:confused:

It does not apply if an aircraft system failure occurs in flight affecting the landing performance. In this case you have to use the actual landing distance. You do not divide it by 0.6 in this situation. (According to Airbus 320 and 340 FCOM )

So technical diversion applies (you do not need to be in an emergency) but for commercial, fuel and wx case I can not say anything either.

But anyway, I think in all these cases excpet an emergency you most probably divert to an airport which is one of your operating areodromes within your company and which means the aeroports have been checked for the Jar regulation of required landing distance.

Hope it helps
