The 767, autoland and the ILS signal
Hi,
While discussing autoland operations on the 767 with some colleagues we could not find a definite answer to the following scenario: performing an autoland approach to CAT 3 minima on a fail operational/AH setup, what would happen if, let say below AH (200ft RA) we loose both LOC and G/S signals.
Some reference sources indicate that the system would remain fail operational and the landing would be performed using IRU data for tracking and radio altimetre information for flare and touchdown, but we could not find this explicity stated on any of our Boeing manuals.
Such event would, according to our airline policy, mean a mandatory G/A anyway
Thanks!
