An electronic monitoring device for monitoring at least one radionavigation signal during an approach phase to a landing runway, related monitoring method and computer program are disclosed. In one aspect, the each radionavigation signal is obtained from a reception chain on board an aircraft. The device includes a calculation module configured to calculate an angular displacement value in a reference plane, a comparison module configured to compare the angular displacement value with the corresponding radionavigation signal, and a warning module to generate a warning signal based on the comparison between the angular displacement value and the corresponding radionavigation signal. The calculation module is configured to calculate the angular displacement value as a function of a magnitude relating to the aircraft course and glide path according to the monitored radionavigation signal, from avionics equipment independent from the reception chain.
