No way. There are too many aspects to SAR for 10 hours per month to be sufficient. Standard decks, downwind decks, left to rights, right to lefts, trapped decks, RIBs, hi-lines, multi-seat dinghies, wets, ejectees, sits, IEC sits, drums, extended cable drums, AHT, navigation, GH, radar let downs, mountains - all by day and by night.
How can ten hours per month be enough for that - especially when pilots have IF stats to complete as well? SAR can be a risky business and serious skill fade afflicts even the most experienced of operators.
