ILS offset confuses RC

Featured Replies

I flew from LIRN to LICR (fs9 with an ATR-72-500). Cruise level was 170.LICR has runway 33 with an ils approach. When RC started vectoring me towards landing at rwy 33, I was coming in from the north-west, ans so the instruction was heading 150- a parallel course. I had the ils frequency in nav1, and noticed that the dme was above 25 nm. I was expexting RC to start me on the turn eastwards and then north to intercept the ils beam, but I was later told (at 28dme) to head 60. I flew north-east for a long time, and realized RC wasn't in charge of the situation. I was not told to turn nw.I looked at the fs9 map view. Hmmm. The ils beam was offset to heading 017, so the approach would have taken me a mile or two to the rwy, with a sharp turn to the north west to touchdown. I've never seen such a big offset angle. Is this what threw RC off?Eytan Ornstein

i have yet to run into an approach, that rc doesn't finish. follow the directions, and try to duplicate the problem. send me the .logi care more about the runway heading than i do the ils heading. but you might have found something, and i'd like to look at it.send the .pln toojd

Here's a link to a plate of this relatively non-standard approach:http://www.vatita.net/download/planning/files/LICR_llz.pdfOn the plate note that DME distances are to the on-airport VOR RCA 111.0 which you might want on your NAV2.NAV1 would have the localizer REG 109.3 which does not have a DME (nor a GS) and is technically not refered to as an ILS.This is best flown by using an IAP because of the unusual pattern required by the valley offset of the high surrounding terrain.As far as getting "forgotten" this can happen when an ATC comm is not acknowledged (if you have the comms with no auto-reply) so ATC in this version is inhibited from giving the next command.Note also the steep vertical slope angle at DME 8.1 inbound at 017o.VOR approaches are here:http://www.vatita.net/download/planning/files/LICR_ial.pdfThe big picture is the STAR here:http://www.vatita.net/download/planning/files/LICR_star.pdf

Thanks Ron for the charts. They look challenging. I'll try flying them without RC first.JD,I'll fly it again and send you the log and pln.Eytan

i flew it last night. interesting approach. i see what you mean. the ils informatino for 33 doesn't even show up as part of the runway information.this would be a good candidate for an iap approach. rc doesn the best it can for every runway for every airport, but there is going to be one or two that i don't handle welljd

JDYes, it's an interesting approach alright. Thanks for making the effort to fly this route.Is your comment also based on the log i'd sent you?Eytan

sometimes it's easier to fly it, than read it. i had the need to fly yesterday, so i flew itjd
