Dunno about the "legalities" of it,
Slash - I think most company procedures require a callout if you exceed 1 dot on G/S or LOC (and in some aircraft, 1 dot will activate a GPWS "
GLIDESLOPE" at 1 1/3 dots below 1,000').......maybe that's why they restrict it to 1 dot low.
One dot at the OM is about 150' difference, and at the threshold would mean a gear height of about 30' instead of 50', so I don't see that they're really gaining too much.
The ones who worry ME, are the guys who intentionally fly
FOUR REDS on a PAPI - "It's okay, I'm only
JUST below the approach path."
Legally - dunno.
Company wise - I guess they're probably within the allowable tolerance if they stay just above 1 dot. The question is, if they are flying 1 dot, is the PNF calling "Glideslope" all the way down the hill?
Betcha if any of 'em prang though, the company will plead complete ignorance of the practice (I'll also bet that no official notice telling them to do it has been issued), and the pilots concerned will find themselves on the market.
IF it's what the company wants, tell them to put it
IN WRITING, as a notice to ALL pilots!!
The name of the survival game is "cover your ass"!
