80 knots standard speed for a PA28, your school is using too low a power setting, a PA28 will happily cruise at 90 to 100 knots.
portsharbourflyer,
Looks like I haven't been explicit enough again!
We use 2400rpm cruise on the Warrior III which indicates at around 100kt. The 80kt I was referring to is the 'slow flight' speed we use to demonstrate (and get them to practice) on the 1st or 2nd lesson. My point is that whilst it IS slower than the cruise, the effects of slow flight aren't nearly as apparent at this speed as they are at 50kt.
18greens,
Very useful post, thanks.
