"Expect an ILS approach"?
Dear ATC folks,
Why do we have on some ATIS nowadays: "Expect an ILS approach"? At an airport equipped with an ILS, that will be the normal approach aid in use. Therefore, stating this every time seems superfluous and wastes time. Would it not be more sensible to normally say nothing about the approach, because all pilots will expect an ILS approach anyway (unless it is NOTAMed off)? Then, ONLY if the ILS or glideslope was off; say "Expect a Localiser/VOR/NDB approach"? This might seem petty, but having to wait for the "expect an ILS approach" before one gets the wind or visibility etc. can be very frustrating. Thanks, U |
dear uplinker:
I think you are quite misguided in your priorities. And it is funny that you don't even mention a visual approach as a possibility. I think the atis format is just fine and if you have to listen a few seconds longer to get the visibility, well...do it. of course if you are single pilot, single radio, you can always advise ATC and request that they READ YOU THE ATIS on the approach freq. |

I was not asking for a facile argument, but a reasoned answer from ATC. Captain Smithy: I totally agree with you so perhaps I didn't write my post very clearly? The point I was trying to make is that we don't need to be told EVERY time to expect an ILS approach - which is the norm - we ONLY need to be told if it is NOT available at short notice. As I say, this particular point might seem petty, but it is one of a number of apparently (to me) uneccessary things that have appeared over the years, and I want to understand the reasons for them.

You fly to that airport all the time, so you are aware of what is the norm but what about a first time pilot to that airport - at least he will know what approach to expect.
ILS could be off for maintenance, so you might hear expect VOR/DME approach next time... Really just giving you a heads up. We dont make the rules, we just abide by them (mostly) :E |
Uplinker,
CAP 493 (MATS Part 1) requires ATC to inform pilots of the approach aid being used. If it's on the ATIS then perhaps that information does not need to be passed over the R/T to each individual pilot, hopefully freeing up the airwaves a little? |
The ATIS message should contain all or part of the following elements of information in the order listed: • Name of aerodrome; • Arrival and/or departure indicator; • Contract type, if communication is via D-ATIS; • Designator; • Time of origin of weather report; • Type of approach to be expected; • Runway(s) in use; status of arresting systems constituting a potential hazard, if any; • Significant runway surface conditions and, if appropriate, braking action; • Holding/departure delay, if appropriate; • Transition level, if applicable; • Other essential operational information, including when LVP are in operation; • Surface wind direction (in degrees magnetic) and speed, including significant variations; • Visibility and, when approved by the Authority, RVR values; • Present weather; • Cloud below 5000 ft, or below the highest minimum sector altitude, whichever is greater; cumulonimbus; if the sky is obscured; vertical visibility when available; • Air temperature and dew point; • Altimeter settings; • Any available information on significant meteorological phenomena in the approach, take-off and climb-out areas; • Trend forecast, when available; • Specific ATIS instructions. Vectoring to Final Approach 9.1 Information to aircraft 9.1.1 On commencement of vectoring to final approach the pilot is to be advised that the aircraft will be vectored to intercept the final approach and of: a) the runway in use; b) the type of final approach; and c) the procedure to be followed in the event of a radio communications failure if this is not published. |
Agree completely with Uplinker, if it is the norm there is no need to state it. Some airfield ATIS's, while no doubt with the best of intentions, are on occasion almost unusable because of the amount of 'additional information' on them - most of which is already in the NOTAMs!
Like all R/T: minimum words for maximum info. |
"Expect ILS approach", by itself is a fairly ambiguous statement.
How do you get from the holding pattern to the localizer? Many years ago, in a galaxy far, far, away, we always stated the type of approach on initial contact with inbound A/C, - Radar vectoring to the ILS, LLZ only, or SRA/PAR, as appropriate. If you depart from our local airport, eastbound, it is always a DESIG SID. If you fly the route frequently, you will know this, but it is always given as an an instruction, and a read back is expected. Anything which prevents that little mouse from completing its run through the block of cheese is O.K. in my book. :ok: |
I always have assumed that the statement "expect an ILS approach" indicates that a visual approach is unlikely due weather conditions. So to me the statement is quite helpful.

billyt,
Before our approach had the facility to 'swing the ILS', to the other end, we would sometimes offer 'radar vectoring to a visual approach' to the reciprocal R/W if the W/V was calm and the METAR and traffic pattern was favourable. Not everyone could accept it though. |
Many of you are answering the question, without realizing the question.
At an airport equipped with an ILS, that will be the normal approach aid in use. Like BillyT states, if most ops are VFR, it is imperative that "expect ILS" is stated. |
dear uplinker
why not just say: weather stinks like usual for the UK by the way, you are right about one thing...IT IS PETTY |
In the UK at least, all RTF is recorded, so by saying 'expect ILS approach' the controller has proof that you have been told ILS approach if an incident occurs and the pilot hasn't paid full attention to the ATIS.

First, little of this is UK-specific, the rules for what should go on the ATIS come from ICAO.
Second, the info is there to assist planning and briefing for the approach. One airport I worked at took the sensible decision not just to include the type of approach but how the pilot can expect to get there - normally "Expect radar vectors to the ILS", but sometimes it had to be "Expect vectors to a visual approach" or "Expect procedural ILS approach depending on serviceability of equipment and so on. As has been pointed out, just because there is an ILS doesn't mean it can be used - I'm sure that knowing this can help planning as opposed to assuming.

Sadly, although NOTAMs are a pretty good idea, many pilots just don't seem to read them or have the foolish idea to take-off before something happens/fails and a NOTAM can be sent. ATC is there, in part, to provide information to help the pilot conduct the flight safely - the general point is that it's better to have something passed to you unnecessarily than not be told something that you need to know.

Obviously never been to Nice then Perfectly serviceable ILS to 04L, only used when people forced to Go Around off the Riveria, or whatever they call it now |
Thank you for the (sensible) replies from ATC. My query was genuine but seems to have been mis-interpreted as me having a go at ATC - I wasn't.
I was merely asking a question and trying to see if things could be streamlined in busy airspace. It seems to me more important to tell us if the approach aid has been downgraded to an NPA or SRA etc. than to tell us every time that the normal approach to the airfield is available? I have been flying commercial jets in Europe and elsewhere for 12 years, and about 95% of all 'my' destinations have ILS's, and about 85% of the time, that IS the approach aid in use and the one I expect. QED. Most replies on this thread seem to misunderstand my point. DB6 gets it. When we are in the cruise, we look through the plates of our destination airport. If the Metars or TAFs are obviously favouring a particular runway, and that runway has an ILS, then that is the approach we will expect - assuming it is not mentioned in the NOTAMs as being U/S, or LOC only. We therefore only need to be told IF the ILS is U/S at short notice and if a LOC or VOR or NDB or visual approach is in use in its place? As regards how to get to the ILS; the Approach/Radar/Tower controller will tell us. My point is that surely 'expect an ILS approach' does not need to be on the ATIS of an ILS equipped airfield? Seven stroker troll - What is your problem pal? Are you one of those who belch or play music on 121.5 and think it's clever? U |

Hi Uplinker,
Just cause there's an ILS doesn't always mean that will always be the approach. In Melbourne Australia the ATIS will sometimes quote "Expect ILS" or "Expect instrument approach" (eg VOR, Localiser, NDB, DME, RNAV, GPS etc) or possibly won't have any approach quoted if visual approaches are in use. Again it will depend on the runway and conditions of course. Another point to consider is that the ILS will be used to start off the approach to get below the cloud or whatever conditions to then conduct a visual approach to final. In this case "Expect ILS" will probably be on the ATIS. The reason for this is the acceptance rate can be increased for visual approaches by using the ILS to start off, but if in IMC and full ILS approaches are needed the arrival rate will blow out and cause more delays. Is that close to what you were after? |
