@Robin & FCS.....what about airplanes that land with autothrottles on but autopilot off for manual landings.As in the 777 maybe.Does the Vref+5 rule still apply? And why is that?
As far as I know, the autothrottle on a large aircraft is FAR slower and more sluggish to react to a change in speed than a pilot controlling the speed on manual thrust.So why the lower additive on automatics than on manuals?The same holds true for an increase in speed....slow on auto than on manual.
Still wondering why...
Thx for all the replies so far.
