Everything is a paper/dongle upgrade, but these things are tightly controlled.
For DL, it will allow DTW to the whole USA. Probably 2500nm still air range, down from 3,100nm. That is sufficient. Maintenance intervals will be extended, ATC fees off a lower MTOW.
There is no range limit, but Bombardier does limit fuel loaded by the dongle purchased.
Thank you for this further explanation. What is a dongle exactly in this case? From my search of the internet this morning, it generically means some type of software that controls functionality. If the aircraft is built a certain way, what cost difference does it make to Bombardier to control how much fuel goes into a tank that is already there? Why would they limit?
Also, does anyone have any numbers in terms of how much thrust and weight are reduced? Is it proportional to maintain a similar thrust to weight ratio?
