👉 Subsonically, also known as Subsonic or Subsonic Flight, is a type of flight that occurs when an aircraft travels at speeds below the speed of sound (approximately 340 meters per second). This means that the aircraft's airspeed is less than about 1.2 times its critical speed, which is approximately 1.65 times the sound speed in air. In subsonic flight, there are no significant changes in altitude or velocity compared to a sup
