For a standard Cessna 172 Skyhawk, the most widely used flight training aircraft, the typical takeoff speed (rotation speed or Vr) is approximately 55 to 60 knots (63 to 69 mph). The exact speed depends on factors like the aircraft's weight, the outside air temperature, and the runway elevation. On a standard day at sea level with a full load, the pilot will pull back on the yoke to lift the nose wheel at about 55 knots, allowing the wings to generate enough lift to become airborne. Once in the air, the aircraft usually climbs at a "best rate of climb" speed (Vy) of about 73 to 75 knots to clear obstacles effectively. Smaller models like the Cessna 150/152 might rotate even slower, around 50 knots. It is vital for pilots to calculate these speeds before every flight using the Pilot's Operating Handbook (POH) to account for current environmental conditions, as high temperatures or heavy cargo can significantly increase the required takeoff roll and speed.
