Abstract: A system for monitoring movements of rotor blades attached by flapping hinges to a central head or hub of a helicopter. At least one sensor is arranged to continuously measure vertical angular movement of a rotor blade and/or the flapping hinge. Also a method for monitoring movements of rotor blades attached by flapping hinges to a central head or hub of a helicopter.
