]The indications on flightdeck are absolutely normal. Except the LOC is not supposed to be there.
Actually, it is. The signal is a side-lobe from the antenna, which is there due to the electronic design of the NAV-AID.
Your picture shows A/C's track similar to final approach course - it is possible if you are flying parallel to the landing direction, but then the "false" loc would steer you towards the antenna, approx 35 degrees in a different direction.
Most likely occurence is:
- on a base leg heading, approximately 35 degress off the final track
- close to the field (12 NM or less)
- significantly below gentlemenlike profile (around 2500 ft aal or lower)
last experience here at 2000 AAL:
