Thanks for post Human Factor, pls see the following examples of what I thought question was about.
.
Non pilot staff works for 24yrs at a basic of 40k, he pays 5.25% into pension each year.
.
Pilot works for 24yrs and his basic rolls from 28k to 52k and he also pays 5.25% into pension each year.
.
So they have both paid in the same about.
.
40k minus the 6k abate = 34k @ 24/56 = pen of about £14,571 PA.
.
52k minus the 6k abate = 46k @ 24/56 = pen of about £19,714 PA.
.
The above example is simple and would need to be refined to get correct value of who gets most out of the pension pot.
.
Also remember BA payments to pension are linked to the staff member payments so this will again roll up the problem. ie, BA have also under funded the pension!
.
With BA saying they put in 3 or 4 times what staff put in makes even more strange pension funding figures?
