Hi Hazed,
This sounds like the 'Tonnage on Target' feature from Warbirds. As a long time bomber pilot and CO of a bomber squadron I know full well the potential of the bombsight we have in AH right now and I think the current setup is fine. I don't want to keep harping on about it but those who complain they cannot hit anything are still using the mentality left over from v1.09 bombing. The new system is a lot more historical and requires pilots to use proper salvo/delay and speed to gain good results and it's not impossible to hit two or more hangars on one pass depending on the type of field being attacked. While my own squad tend to hit strategic targets we do also attack fields and I really don't see the problem.
What you propose may help the new guys but would make bombing incredibly simplistic and not very historical. At the moment to hit a field you need to co-ordinate either with other bombers or heavy fighters to finish the job you start with the bombers. Part of the skill of bombing now IMHO is not only the formation flying but the correct selection of salvo and delay and also picking the best lines across the field to drop your ord.
In the following picture I used a salvo of 14 with a 0.70 delay flying at 160 indicated:

At a full field it is quite conceivable to destroy this field with 5 bombers which really is not that much. To use a tonnage on target system takes away the skill of picking out these salvo's, delays and lines of attack and I would be very much against such a system.
Bombers need to practise, my squad did and got the system working fine for us within a few nights practise. If anything now we have to spend more time in the norden sight I think it's time to introduce autogunners for bombers.
