Just thought I'd cast this into the pool of knowledge...
Someone recently said to me that, for mechanical reasoning, extending the gear in a 210 should be limited to straight and level flight and I am trying to work out what the rational for this would be.
I would have thought that provided the aircraft was flown coordinated, the direction of gravitational forces and airflow would act on the gear system the same as in S&L flight. (Although obviously the amount g loading would vary).
... As the old professor would say, "Why is it so?"
