The sleep state, or the state in which at least some operations are locked, is also referred to as a first state. The state in which the sleep or lock is released is also referred to as a second state. The predetermined input may be, for example, pressing the power key, inputting a character string such as a password to the input unit 24, or biometric information of the user read by the sensor unit 23. The predetermined input may be a gesture of the user detected by a camera or the like, or a voice of the user detected by a microphone or the like.

The communication terminal 20 may automatically transition from the first state to the second state when mounted on the flying object 10. The communication terminal 20 may transition from the first state to the second state based on the input of the user regardless of whether or not the communication terminal 20 is mounted on the flying object 10. The communication terminal 20 may transition to the first state when the flying object 10 on which the communication terminal 20 is mounted is floating. In this case, the communication terminal 20 may be configured so that the user can transition to the second state by an operation that does not directly touch the communication terminal 20 or the flying object 10.
