ABSTRACT:
A safety device to warn the pilot of a hang glider if take-off is attempted without the glider hook-up strap being connected to the pilot's harness includes two sensors arranged in series with an alarm. One of the sensors is arranged to close a circuit when the glider is positioned in a take-off attitude and the other sensor closes a circuit when the free end of the hook-up strap is disconnected from the pilot's harness. The alarm is activated when both circuits are closed.
