Commercial Aircraft Altitudes
- Regarding commercial aircraft, the Boeing 747 reaches 13,700 meters, and the Concorde reaches 16,700 meters.
- Why don’t planes fly above 10,000 meters? This is because the lower the air density, the less oxygen it contains, which is one of the fuels for piston engines.
-
Altitudes and Speeds
- Piston engine aircraft fly at altitudes between 10,000 and 15,000 feet (4,500 meters).
- On average, airliners fly at a speed of 0.8 Mach, approximately 980 km/h.
-
Bird Altitudes and Fastest Aircraft
- Birds typically fly between 300 and 1,000 meters during migratory flights, rarely exceeding 2,000 meters.
- The SR-71 "Blackbird" holds the record for jet engines’ speed at 3,529.56 km/h.
