Almost all airplanes hit the runway vertically less than a 100 feet per minute, which is like less than traveling 2 feet per second. However, the horizontal speed varies greatly. Glides can land at speeds below 40 mph, while large comerical airliners will land at around 150-170 mph. It depends on the design of the wing, the wing loading, and most importantly, when it will stall. Almost all aircraft basically stall (sometimes fully, sometines partically) upon landing.
  Generally it depends on the weight of the airplane. Light airplane like Cessna 172 can take off at about 60mph, heavy airplane like Boeing 747 needs 180mph to get airb â¦ orne!   * Speeds vary depending on type of aircraft, weight, and enviromental conditions. The speed that a mach number relates to differs with altitude, temperature and air density. But in general terms, if a plane flies Mach .8 at 37000 feet, the speed is around 850 km/h, 520 m/h or 450 knots.
