From post 1053 re. Boeing's message ;
"(Extract) ........... If one LRRA provides erroneous altitude readings, typical flight deck effects, which require flight crew intervention whether or not accompanied by an LRRA fault flag, include:
- Large differences between displayed radio altitudes, including radio altitude readings of -8 feet in flight.
................."
Does that mean that the "fault" reading of a RA is "-8 ft" or merely that a reading of -8 ft whilst in flight is indicative of a RA failure ?
