2. ID#Unit (function)Failure modePossible causeLocal effectsSystem effectsRemedial action H1.1GSM-modem (exchange data between the ground based and the airborne system). Connection could be disrupted Antenna failure Obstacles breaking the connection Data is not transferred Corrupted data transmitted Loss of contact with the eyebot High quality equipment Manual control of the plane H1.2Serial failure between GSM modem and Eyebot Misprogramming Wire failure between eyebot and GSM modem Physical damage to port Corrupted communication Loss of contact with the eyebot High quality equipment H1.3GSM failsShort circuit Battery runs out Physical failure Data transmission failure Loss of contact with main computer Manual control of the plane H1.4

3. ID#Unit (function)Failure modePossible causeLocal effectsSystem effectsRemedial action H2.1GPS (register where the plane is in a three dimensional form (longitude, latitude and altitude). GPS failsBattery runs out Physical failure Short circuit The GPS will not be able to calculate plane location Don’t see the plane (Eyebot won’t get the information) Emergency call for location signal Use last calculated position H2.2False information transmitted Programming errorMiscalulated locationFalse location data New instructions based on false data Emergency call for location signal (GPS fail assumed) H2.3Serial failure between GPS and Eyebot Wire failure Misprogramming Port failure GPS will not be able to transmit data No location data received Emergency call H2.4Sattelite connection fault Disrupted connection Receiver failure False, corrupted or no data at all No or false location received on the ground High quality equipment

4. ID#Unit (function)Failure modePossible causeLocal effectsSystem effectsRemedial action H3.1Eyebot-controller (controls the incoming data from the GPS, the outgoing and incoming data from the GSM and finally it runs the servos that control the airplane (rudder, elevator and throttle). This component also has a microphone attached to it) Eyebot failsPhysical failure Battery runs out Misprogramming Short circuit Data received not analyzed No control data sent to the system No operations performed caused by lack of data Backup battery Switch to manual control Simulation based on last received location H3.2Serial port failure (input ports) Wire failure Port daamge High temperature Fluids Won’t receive data from GPS, GSM modem and / or Gyro False data No input dataIn case of GPS failure, emergency call In case of GSM modem failure, switch to manual control Data comparison (by checksum) High quality components H3.3Servo port failure (output port) Wire failure Port damage High temperature fluids Won’t send data, or send corrupted data System will fly the plane based on no or false data Switch to manual control

5. ID#Unit (function)Failure modePossible causeLocal effectsSystem effectsRemedial action H4.1Servos switch (decides if it is the servo positions from the RC receiver or the Eyebot that will be chosen) Switch failurePhysical damageWon’t be able to switch between automatic and manual control Either the RC Receiver or the Eyebot control will be obsolete Backup switch Or-gate possibility H4.2Servo in Ax port failure Physical damage Wire failure Data corruption No data received from the RC Receiver No data for manual control Processing unit for default values in single port failure H4.3 H4.4
