we are just proposing mods to improve DOC so I best come in with something as opposed to saying that its a pointless exercise and I should get and A for doing no work on this whatsoever as the F27 is not worthy of being modded at this time in history.
I disagree.
If you were to take a selection of the technically-feasible mods that have been mooted here and, after a careful cost/benefit analysis, conclude that none of them generated a positive net value over a reasonable period, then that would (or should) satisfy the aims of your assignment.
If, on the other hand, you are expected to come up with cost-effective mods that would pay back the non-recurring cost with DOC savings, and that no F-27 operator in the last 55 years has though of, then you should be seriously considering changing your tutor or educational institution.
