Do pilots understand what the LSA is?
The LSA or Localiser Sensetive Area, Do you guys in the tube know what we mean when during foggy weather (ie wednesday) we say vacate right and taxi clear of the LSA. Some seemed to call just clear of the runway.
However the LSA will extend beyond the edges of the runway and the colour coded turn off lights only tell you when the nose is clear and not the economy section.
BTW the LSA at LHR extends 137m either side of the runway centreline, so you have to really be on the outer taxiway to be well clear. Does this info appear in any of your books?
Landing clearance ideally is given by 2dme in LVPs, but can be given by 1nm, if not the a/c is sent around. (Sorry to those who went around)

For what it's worth, I always teach when doing LVPs in the sim that the whole of the A/C must be clear of the lights, as you point out. Some places (LGW, if I remember correctly?) only require a pilot report if ASMI is u/s.
First time I've ever heard of the expression 'LSA' as just initials.

I am currently studying JAR ATPL correspondence course and there are about two pages on sensitive areas for ILS/MLS. Also mention of taxiway lighting in sensitive area. Maybe JAR syllabus is not totally bad after all.
Did I really just write that? Must be studying too hard

In Jeppesens the info is normally on the back of the taxi chart for the particular airfield. The AIP calls it the ILS sensitive area AD 1.1.1 para 13.4 or look at this link (adobe acrobat required): http://www.ais.org.uk/uk_aip/pdf/ad/30101.pdf

C2L27L,
Worry when your GMR or SMR or whatever they want to call it this week isn't working. If it's not, the only way you can be sure is when the pilot reports facing East, West etc on the taxiway. But even then would you trust them when so many report 'vacated' as soon as their nose wheel has left the runway centreline?
I guess that as long as you know when they have vacated the runway or LSA it doesn't really matter if they know as well. Let's face it they are only pilots afterall. (Sorry guys and gals [no really I am {he said smiling}])

Don't want to appear cynical.. but have you tried asking copilots (and even some captains) how you go about a circling approach?.. restrictions, limitations etc..?
I am afraid that in terms of general knowledgebilty (pardon my lousy spelling) the standards are lower than what they used to be.. IMVHO of course.

never mentioned in the UK IR or maybe I forgot. However the FAA put great emphasis on the hold short lines for the "ILS sensitive area". I'm not certified for anything other than CAT 1 landings, but under Part 91 a Zero/Zero take off is permitted, and as a result its important that Pilot's be familiar with Hold short lines in Low vis Procedures. I would imagine that the exit line is in the same place as the entry ilne.
