most aircraft could use a 4 degrees glideslope with enough thrust for safety reasons when in an available final configuration but with less thrust than we use now and if last 5000ft (
tbd) are flown in this final configuration stress levels will fall drastically not only for people below but also for pilots, especially, when tailwindlimits above 10kts as allowed nowadays on some airbus aircraft are cut back to 10kts to avoid idle landings...
Won't work in the U.S. for airline airports. The FAA is hard over on 1,000 feet per mile max vertical descent and definately not engines at idle from 1,000, feet agl until in the flare. The 1,000 feet max v/s came from an NTSB recommendation.
