ambidextrous
Thanks ChristiaanJ#1508 and CliveL#1509. That's what I thought. It was the quote in #1504 that implied left and right handed engines with all the stock problems that would cause.
At risk of thread drift I think that anything with propellers would be likely to suffer much more from asymmetry, but I think folk just put up with it - except in the few cases where there are contrarotating propellers.
Am I right in thinking that once the necessary minimum rpm was achieved, reheat was selected on all four engines, but that some (automatic?) control restricted the power to engine#4 until 60kt was achieved?
