The present invention discloses an aircraft control method and an aircraft. The method comprises the steps of monitoring the test value of a barometric altimeter and/or a GPS, judging whether the barometric altimeter and/or the GPS is abnormal or failed according to the monitored test value of the barometric altimeter and/or the GPS, and carrying out protection controlling on the aircraft with preset protective measures when the barometric altimeter and/or the GPS is abnormal or failed. According to the aircraft control method and the aircraft, the effective control and protection of the aircraft can be realized when the barometric altimeter and/or the GPS is abnormal or failed, and the flight safety of the aircraft is improved.
