my proposal then
You guys are smart I'll give you that.
Now, here is my proposal and I hope it is taken very seriously because it might be the wave of the future.
You must have three engines on your helicopter. Two will operate at all times until one craps out. The third engine will automatically start and run up using the FADEC etc. and you will then be able to simply continue your mission as if nothing has happenned. I would love to see the safety factor calculation of this proposal.
A further question for the mathematicians: How many engines would be necessary before the increase in safety factor becomes so small that it is no longer worth it to add any more engines. I personally think the answer will be three but no more. In any case, if adding a third engine would significantly increase the safety margins for all helicopter operations then I support it fully.
Cheers,
