Is it rare in helicopters of any type for up to 15% of fuel to be unusable if pumps are not working?
Based on comments here, should pilots be more aware of the difference between useable fuel under normal ops compared to when pumps are not operating?
In the case of the EC 135 apparently it is 1.5% versus 15%.
The entire safety margin if flying by the clock!
I can't find any reference in flight manuals to unusable fuel with pumps off.
A case of the manufacturers and industry relying too much on the electronic cockpit?
