I turned in all my books 9 years ago but recall flaps 25 for an overweight landing and 15 for single engine approach, otherwise 30. We were also 767 qualified so with no books am unable to research it. I always landed flaps 30 even at the special airports we had. TGU was the most restrictive airport our airline flew into in Honduras and I chose that one because it was a lot of fun and challenging. TGU made number one of the most dangerous airports in the world to fly into with a jet airliner on a TV show.
If you want to see my retirement flight in 2003 go to
Flightlevel350.com: Free Aviation Videos, Airplane Videos and Cockpit Videos and search MHTG. I am the 7th video down. We couldn't return with an engine failure because flaps 15 wouldn't give us enough runway. It had 5400 ft useable. We had to use a military base 30 miles away if necessary.
You probably aren't what you project yourself as so will give you a break. We all just want to retire and go fishing.
