But they are behind the pivot point of the mainwheel contact, which is the
point about which the aircraft rotates when on the ground. So statically it
is better, dynamically i.e. if it rolls and you brake, it is worse as said.
I had this disaster (static situation) in 1997 and the height of the c.of g.
was (is?) not known at Europa. It would be difficult to find out without
suspending the aircraft vertically and measuring the displacement of the
longit axis. Establishing a limit would be even more of a problem. All
loads, baggage, passengers, fuel, even instrument panels, aggravate the
dynamic problem as they are above the pivot point, wherever the c.of g. ends
up. Have adopted the technique of closing the throttle immediately static
rpm is seen to be satisfactory.
