I'm sorry -- I haven't really worked on the PA-28 for ages. I agree that it should be a high priority, along with the other common student trainers we're still missing, the DA-20 Katana, C-150, and C-152. Here are some operational speeds for the PA-28-161 (they'll be different for other Cherokees). Note that we do not currently model the difference between indicated and calibrated airspeed, which is typically quite significant at cruise speed and near the stall: the real (calibrated) speeds will be higher near the stall and lower near Vne. Note also that most of these speeds actually vary according to the square of the gross weight, so Vso or Vx (for example) is lower when the plane is under 2440 lb: Vne 160 kias Vno 126 kias Vfe 103 kias Va 88-111 kias Vs 50 kias Vso 44 kias Vglide 73 kias Vx 63 kias Vy 79 kias Vrotate 40-52 kias Vx (25 deg flaps) 44-57 kias Enroute climb 87 kias Vapproach 70 kias Vapproach (40 deg flaps) 63 kias For performance, the PA-28-161 is supposed to be able to do 126 ktas at 8000 ft burning 10 gph at best-power leaning, or about 123 kias burning at 8.5 gph at best-economy leaning (my experience is closer to 7.6 gph). Climb at sea level at maximum gross weight is 660 fpm. With just one or two people on board, the plane normally climbs over 1000 fpm near sea level.
