Are B757/B767 ILS landings only performed by auto-pilot or also manually?
Regarding air shows:
Are accurate manual B757/B767 near-airport approaches and landings (when runway is visible) performed without airport based navigation signals?
Can a consistent glidepath (10 miles distant for example) be established for a runway touchdown without ILS or other nav-aid or would constant adjustments become necessary?
Can B757s/B767s be manually centered properly over a runway without difficulty, without ILS guidance? (Air show fly-bys for example) Would excess speed increase the level of difficulty?
(If these questions seem "dumb", it's only because I am.)
