FIS
I don't only fly from Barton (which isn't always soft, but is always bumpy
) but regularly visit hard runways. For many years I used to fly a Manchester-based 172, and did para dropping off a hard runway. I've never used a 'rotate speed' in a light single. I have many types in my P1 column as well, taildraggers and trikes, and though I have little experience of the PA28 I don't remember it being that different.
Maybe I've been doing it wrong all these years
"Airspeed building both sides (or front and back, as appropriate). 60 knots. 100. V1. Rotate. Positive rate. Gear up". Nah. Not even in the Yak
