Yes definitely, this could only be in the UK! Don't know if we should name and shame here? But it was an airport slightly South of a large river in the North East after which the airport is named...? Bonkers yes, but it was good fun to say the least. My little stubs had never scribbled so quickly either! ;)

OMG. What would he be like on an ASR approach? ;)
You kinda wonder why there are capacity issues at some airports. |
Said airport now up for sale.

Localizer range
Can somebody point out where to get the info on the range of the localizer (25nm) and the glideslope?

Can somebody point out where to get the info on the clibration range of the localizer and the glideslope. Was told that localizer is 25nm but i dont know where the info comes from.

5. The localizer provides course guidance throughout the descent path to the runway threshold from a distance of 18 NM from the antenna between an altitude of 1,000 feet above the highest terrain along the course line and 4,500 feet above the elevation of the antenna sight. Proper off-course indications are provided throughout the following angular areas of the operational service volume:
(a) To 10 degrees either side of the course along a radius of 18 NM from the antenna, and (b) from 10 to 35 degrees either side of the course along a radius of 10 NM [...] 6. Unreliable signals may be received outside these areas. 3. The glode path projection angle is normally adjusted to 3 degrees above horizontal sothat it intersects the MM at about 200 feet and the OM at about 1,400 feet above the runway elevation. The glide slope is normally usable to the distance of 10 NM. However, at some locations, the glide slope has been certified for an extended service volume which exceeds 10 NM. |
In the past I was always taught it is OK to report "localiser established" when turning onto the localiser and the LOC deflection is under half scale. However on a recent flight I was told that is a "fail" because one is not fully established. But the ILS flying tolerance is half scale or better, all the way down, so how can it be a fail? Sometimes you want to get the report in nice and early, before somebody else jumps on the radio with their inside leg measurements Google is a bit ambiguous on this, and of course in the USA (IIRC, from the FAA IR) they don't use the phrase, because once you are "cleared for the ILS" you can descend to the platform (if procedural) and just fly it all the way short of a landing clearance. The fact that you want to fly an ILS a whole lot more accurately than 1/2 scale, especially when far out, is besides the point in this question, IMHO. We'll leave aside the 'fully established' thing because I think you're intelligent enough to know what that means, but... How many times do people have to be told to find the proper reference? Google search results are not written by the regulators. How many posts before someone turned up with the basic knowledge the question needed? If you don't know what's in PANS-OPS, then... |

Before you get over-excited (again) and start taking the p1ss out of me (again) I suggest you notice the dates on postings, before you respond to an old thread :E |
