Touchdown point
Hello guys
FAA SAFO19001 of 3/11/19 in para g TOUCHDOWN POINT gives air distance as 1500ft or 07 secs to touchdown. It also states that operators can use shorter distance of 1000ft or 04 secs to touchdown provided some requirements given there are fulfilled.
I have seen all Airbus operators using 7 secs to touchdown. Are there any Boeing 737 carriers who use 4 secs or 1000ft to touchdown? If so Are they giving required training?
