Benefits of leaving off thrust reversers?

Tue Jul 11, 2017 6:36 am

So I've always wondered why the KC-135R's CFM engines have no thrust reverse function when the previous -135E's did. To this extent I understand the same goes for the KC-46.

With the A380 there was a operational reason related to the wingspan and how far the #1 and #4 engines hung out over the unpaved areas.

Does the weight savings offset the increase in brake wear for the KC aircraft? Also this approach was not taken for the purpose built KC-10.

Any insight?

Most likely to save money on engine complexity, MX, parts, etc.
When it absolutely positively has to be there ... at some point.
