I have a question for active B747-400 pilots. Being retired for almost 10 years, its too long ago to answer the question myself. Some of you here talk about FR24 Data show a stable approach, others talk about a decellerated approach, all the way down. Most of you seem to agree, the data show a three degree approach angle, between 300 and 500 ft above the ILS Glideslope. My question: would it be possible to program the FMCs to perform a LNAV/VNAV approach with RW26 as active runway, but with final descent waypoint (mistakably) threshold RW08? I could not think of a good reason to use such a construction under the prevailing conditions, so I want to emphasize, its a technical question only.
By the way, I have seen Map shifts on the B747-400 on numerous occasions, even up to 6 nm, but it was back in days, where our 747's were not yet equipped with GPS. Didn't observe them after GPS installment. Assume MyCargo Airlines fleet of 8 747's was GPS equipped.
