A Boeing 737 (including the NG and MAX variants) typically touches down at a speed between 130 and 150 knots (150–172 mph / 240–277 km/h). The exact "touchdown speed" is influenced by several factors: 1. Weight: A "heavy" plane returning from a long-haul ferry flight or carrying a full load of passengers requires a higher speed to maintain lift; 2. Flap Setting: Most 737s land with "Flaps 30" or "Flaps 40" to create maximum lift at the lowest possible speed; 3. Environmental Conditions: Higher altitudes (like Denver) or high temperatures require faster landing speeds because the air is "thinner." In 2026, pilots use onboard performance computers to calculate a specific "Vref" speed (reference speed) for every landing, which is usually around 1.3 times the stall speed. If the plane has a strong headwind, the "ground speed" might be lower, but the "airspeed" over the wings remains in that 130–150 knot range to ensure a safe, stable flare and touchdown on the runway numbers.
