UNMANNED AERIAL VEHICLE LANDING SYSTEM
First Claim
1. An unmanned aerial vehicle configured to operate in a plurality of operating modes, said unmanned aerial vehicle comprisinga sensor system, anda flight control system comprising a diagnostic module communicatively coupled with the sensor system, which diagnostic module is configured to initiate an operation mode of the unmanned aerial vehicle, which operation mode is selected from the group consisting ofa first mode, wherein said first mode is a normal operation mode configured to be used when no errors are detected;
- a second mode, wherein said second mode is a safe landing mode configured to be initiated when one or more non-critical components of the unmanned aerial vehicle are in a non-responsive mode or not working according to pre-defined conditions; and
a third mode, wherein said third mode is an emergency landing mode configured to be initiated when one or more critical components of the unmanned aerial vehicle are in non-responsive mode or not working according to pre-defined conditions;
wherein said second mode is configured to override said first mode and said third mode is configured to override both said first mode and said second mode.

Abstract
The present disclosure provides an unmanned flying vehicle (UAV) operable in a plurality of operating modes including a normal operations mode, a safe landing mode and an emergency landing mode. The normal operations mode is initiated when no errors are detected in the system. The safe landing mode is initiated when one or more non-critical components of the UAV are in non-responsive mode or do not work as desired. The emergency landing mode is initiated when one or more critical components are in non-responsive mode or do not work as desired. Further, the safe landing mode overrides the normal operations mode and the emergency landing mode overrides both the normal operations mode and the safe landing mode.
