Crab,
On the Sea King, what's the indicator/s of uncontained oil loss - temp, quantity, both ? If 150 degrees C is the maximum allowed after ELS activation, what flight constraints (Tq/V/Alt etc....also taking into account min. requirements for Autorotation) would there be to keep it under the 150 ? if possible ?
If it is possible, what prevents continued ELS protection - lack of spare resevoir or does the heat generation just overtake the ELS cooling capability after a certain period ?
