Here is some RW information for you.

Big thanks to Kendo Selmi EZY4531 for this.

Alternate airports........

4 are normally chosen.

_C1
_C2
_C3
 C's meaning Commercial, because they are airports where the company is actually flying to

The fourth one is the F : fuel alternate which might be any airport in the shortest range around your scheduled arrival field...

An example:
Heading to LIPZ
C1= LIPE
C2= LIPQ
C3= LIMC
F  = LIPH

The captain has the responsibility to choose one of those in the case of a diversion.

..........................................................

 Change.......
Tailwind Policy is now up to 15knt.

......................................................................

Thrust reduction altitude is 1000/1000 acc in 90% of the cases.

Otherwise if the airport  has a proper policy for the noise abatement procedure, that will be 1000/3000ft disregarding the airport policy.

Cost Index

C I is 8 then 0 between FL100 and Cruise Level then back to 8
