Top opportunity

Know your rotation speed

Departure Roll

A typical trainer rotates in the mid-50s of knots - a 172 at around 55 KIAS, climbing out at a Vy in the low 70s, though check your own POH rather than memorising Cessna's numbers - and the transferable rule is that Vr sits just above the stall speed in takeoff configuration. Rotate early because "it felt ready" and the aircraft lifts off inside ground effect, where induced drag is reduced, then climbs out of it into more drag. On a marginal-performance day the result is an aircraft that lifts off and then refuses to climb, sagging back towards the runway.
