a) Abandon the flight and land on the nearest platform
b) Abandon the flight and ditch immediately
c) Continue flight to base
Whether the RFM changes will depend on what it currently says!
a) is LAND AS SOON AS POSSIBLE, which I assume is the current guidance
b) is clearly a nonsense and will never appear in an RFM (would make fitting new gearboxes a risky activity!)
c) is LAND AS SOON AS PRACTICAL and is not the normal guidance for an MGB CHIP
If EC suggest 'PRACTICAL' rather than 'POSSIBLE' then probably it will change.
(of course, entirely irrelevant to the accident in question, as the poor crew had no opportunity to choose their options)
