An airline pilot(Lloyd Bridges)takes his family for a flight in a single engine aircraft,forced to land, the kids flatten the battery overnight by listening to the radio in the cabin & the next day the wife (spoilt) relents & helps to clear rocks to form a runway. Been seaching for many years, can anybody help please?

Sounds a lot like "Lost Flight" from 1969, but it's an airliner not a single-engine.

You're very welcome. Sorry, I'm not sure about your other film. It might help if you add other details like what era it's from, what genre and anything else you remember.
