Theoretically speaking, rib fracture does not affect airplane flying. After rib fracture, the main manifestation is chest pain, and the pain is aggravated when breathing deeply, but it does not affect airplane flying without affecting breathing function. Although the air is thin at high altitude, airplanes are pressurized cabins with enough oxygen to maintain normal breathing, so the absence of chest tightness and breath-holding does not affect the situation. For patients with unilateral multiple rib fractures causing shackle chest, the respiratory function itself is affected, and it is difficult to maintain normal life on the ground, so it is absolutely not allowed to fly with chest tightness and breath-holding. Therefore, whether or not you can fly depends mainly on the degree of smooth breathing. In addition to the pain, the rib fracture mainly affects breathing, and the pain will not be aggravated in the plane, so it is mainly the respiratory function that is affected more obviously.
