Hi LH2:
Let me clarify why I rejected at that point in the take off roll....remember I was still on the runway and not at VR with sufficient room ahead of me to stop safely before I would reach the airport boundary.
the reason being I wouldn't know if they are both going to cut off at roughly the same time.
The PBY has a dead man switch on the mag selector that kills the magnetos on both engines.
If one engine had quit and the other had not it would have been instantly evident and I could have pushed the push pull switch back to the live position. Furthermore if you read my post again you will note that I also selected ICO ( idle cut off ) on both engine mixture controls......the odds of either engine not stopping in the above scenario are remote to say the least.
If they decide not to, then we're back to square one as regards asymmetric thrust--bad news, especially if below Vmcg.
Had I been unable to shut down both engines I would still have had the option of continuing the take off.......
Remember each of these situations are airplane specific and we react based on knowledge of the airplane systems and performance, then make decisions based on what we decide will give the safest outcome.....
The not doing something stupid part of this story was meant to point out had I acted by rote which is to close both throttles to reject a take off I deffinately would have had a directional control problem on my hands.
Therefore it is advisable to think before acting was my message.
