Fail Safes Power Source - Batteries Multiple batteries with separate connections Separate batteries for aircraft power vs other systems Voltage level warnings to pilot Min voltage level set so that there is still extra power in the event of emergency Engine - Motors The more motors the better Most flight controller modules can adjust for loss of one motor if the RPA has six or more motors Communication loss - between pilot and aircraft Avoiding communication loss Multiple receiver antennas - positioned at very different locations on aircraft Monitor battery voltage on transmitter and receiver Monitor obstacles and distance from aircraft "Binding" of transmitter to receiver (avoid interference) Fail safe in the event of communication loss Many flight controllers have a fail safe mode Make sure it is SET UP and TESTED Set up a switch to be able to activate manually Typical fail safe modes for communication loss Hover Return to home
