An aircraft has an energy battery, a power battery, lifting rotors and cruise propellers and is configured such that the energy battery supplies the cruise propellers in cruising phases and the power battery supplies the lifting rotors in take-off and landing phases. The aircraft also includes a reserve power battery. The reserve power battery is configured to selectively supply power to the lifting rotors in an emergency. The reserve power battery is rechargeable, and, during the cruising phases, the energy battery is configured to charge the power battery and the reserve power battery.
