Question....
Workload of twins vice singles while well checking or otherwise engaging in "rat killing" in the field....as I see it...you start two engines up....vice one....push levers up to fly...or roll throttles up to fly....start your lilypad hopping...rolling throttles/pushing-pulling levers up and down as needed....till you either shut down to refuel or hot refuel....all that I see clearly.
What I do not see is the "excessive workload" involved....am I missing something here? Other than the full startup checklist...the workload is the same with the exception of an extra lever or throttle that is moved simultaneously with the other.
Pretty lame reasoning for refusing a twin over a single in my book.
