or a ELS such as the S61 which has a published 120 minutes limit at Vy? (RFM: proceed to nearest landing site at an airspeed of approx 70 -90 knots).
Unfortunately this is a misconception about the ELS on the S61.
The 120 minutes mentioned in the RFM deals with the maximum time allowed for the electric ELS pump, not how long the MGB can be flown on ELS. The ELS system only supplies oil to the babbitt bearings, which would not survive more than a few seconds without oil, which would then either cause the engine inputs to seize or cause a fire in the magnesium gearbox.....catastrophic.
I hope S61 crews are not lulled into thinking they can fly for 120 mins on ELS.
