One of my "Firm Landings".....
Well, the landing distance numbers have been published based on a test
pilot(s), crossing the fence at exactly 50 feet, at exacty Vref (Vls), very little flare (firm landing.....what I was known for :> :> :>), and standing on the
brakes....maximum braking. The aircraft comes to a complete stop....and some guy gets out the tape measure....measuring from the runway threshold to the nose gear. (I guess it's to the nose gear?????) Any different technique in landing, and the published landing distance figures are out the window.
The FAA and NTSB, really aftter the Southwest accident in Midway, decided we pilots need "realistic" numbers upon which we base our decisions. Example: gusty crosswinds...well, we usually add a knot or two to our approach speed for that...well, that adds to the landing distance. Oh, we flare a bit longer than we should to get a little smoother landing....well, that skews the landing distance numbers, too. Or, we don't stand on the brakes, or use auto-brake....well, that adds to the landing distance numbers. Brakes, tires, runway surface not quite up to par....again, longer landing distance.
Personally, I like what I see. Being retired, I don't use the new system. So, my opinion is meaningless.
