OK :
First a broken throttle is not an engine failure, but do we want to get airborne in a very heavy air tanker with one engine ( P&W R1830 ) at full rated power and risk exceeding the max full power time limit? Furthermore suppose for some reason there is a problem dropping the long term retardent?And do I want to wrestle this thing back on to a narrow runway on one engine with the serious x/wind?
Anyhow I rejected the takeoff and at the same time dropped the load.
Getting back to rote learned proceedures, if I had reacted in the normal manner and pulled the power by closing the remaining throttle I would have become the biggest most powerful tree cutter in the province.
The actions I took were because the mixtures were above and behind me and I was unable to use the intercom to get the first officer to pull the mixture levers down to ICO due to the horrendous noise these things make under full power I reached down and pulled the ignition kill switch....instant both engines off solution. And of course at the same instant with my other hand I pushed the drop button to get rid of the nine thousand pounds of retardent in the tank. ( The province didn't even pay me for painting the gravel strip bright red. )
Soooo as all this happened just as we were coming up on VR and the time frame to recognize the danger, make the decision and choose the safest method to stop both engines at once was very, very limited........
The secret is do not perform rote learned proceedures before you pause and think it out.
That is if you wish to stay alive.
