    It's just that with the mean direction at 210 the individual gusts will usually be from a more westerly direction (gusts usually come from the right of the mean direction), meaning they would probably be fully across the runway. When the runway is wet the crosswind limits come down considerably, so we could then be into the territory where a 30-kt gust is at the limit of say a Stobart.

    Gusts usually come the right of the mean direction? While that may be somewhat true, its not used in measurement of crosswind limits as that's not a general rule. 210 degrees is also SSW, and only a 40 degrees crosswind on RWY 17 (170 degrees). The wet crosswind limit for a stobart is 25kts (I think...), but from that direction I'd guess you need a 35-40kt gust for it to go out of limits and 27kts is falling short of that.

    The rule for pilots is if it goes 60 degrees or more off runway heading then take it as full crosswind.

    It is a general rule that gusts will come from the right. That is why if the wind is full crosswind, always land on the runway heading that has the wind coming from your left. This will mean any gusts will be more aligned with the runway.

    Gosh, Santa must have a transponder on the sleigh!

    Next he'll be on social media... :D

    Antonov AN12 buzzed its way over Dublin at 6:00 earlier on route to Prestwick. Even at FL230, the racket sounded superb!

    Hearing in a shop on the radio (not sure what station) a report on the "incident" at Dublin airport the other day, with the aircraft rolling down the runway and another aircraft having to go around. To my mind it seems like an unimportant incident that happens alot but there's alot of hysteria about it on the radio.

    That was a proximity alert that occurred last March. They have instigated some new rules relating to it this week.

    Would say its a loss of separation last March report thsts out today.

    The report and interview with an "expert" carried on RTE Radio 1 was poor and would not leave a lay person much the wiser. The report itself is here:
    http://www.aaiu.ie/sites/default/files/report-attachments/REPORT%202015-022.pdf

    The official synopsis is:

    "On the evening of 8 March 2015, the Air Movements Controller (AMC) at Dublin Airport (EIDW) reported a loss of separation between a departing and a landing aircraft.

    The departing aircraft (EI-EFF, using ‘callsign 342’) was cleared for take-off with a landing aircraft (EI-DHA, using ‘callsign 45TR’) at 3.2 NM on final approach to the same runway. Re-appraising the situation, the AMC attempted to stop the departing aircraft at the holding point, however, as a result of a blocked transmission the departing aircraft continued past the stop line which was in accordance with its previously issued clearance.

    Clearing the departing aircraft for an immediate take-off, the departing aircraft became airborne prior to the arriving aircraft touching down. A runway occupation alert, a function of the Advanced Surface Movements Guidance and Control System (A-SMGCS), activated as a result of the reduced separation between the aircraft during the event."

    This is the nub of the issue -

    "the AMC attempted to stop the departing aircraft at the holding point, however, as a result of a blocked transmission the departing aircraft continued past the stop line which was in accordance with its previously issued clearance."

    AFAIK this is not the first time this has occurred - the depart point of the 28 runway at Dublin is fairly congested; there was an incident a while back with an aircraft in the wrong place. The blocked transmission may be due to the physical congestion. Haven't read the whole report yet.

    One from earlier today, spreading Christmas greetings around the Highlands:

    http://fr24.com/2015-12-24/11:05/MERYXMAS/85b132d


  • Registered Users, Registered Users 2 Posts: 837 ✭✭✭BarryM


    Further info -

    "However, this transmission from the AMC was crossed by a simultaneous
    transmission; the source of the simultaneous transmission could not be determined as no
    other aircraft or vehicle made a call subsequently"

    No AAIU recommendations in the report, but -

    "Subsequent to this incident, the IAA installed a ‘Time to Touchdown’ facility (TTT) for the
    Tower Controller (AMC) which displays the time to touchdown of the next aircraft on final
    approach. Associated Air Traffic Control procedures have been developed, safety assessed
    and implemented and the use of TTT should greatly reduce the risk of the event occurring in
    the future."

    Dublin is heading for a requirement for two parallel runways, one for takeoff one for landing; but traffic is |"bursty" and much of the time one runway is fine. I think I saw recently something about a new runway in planning.

    Hmm, I assume that IST-SNN-ORD flight won't run tomorrow? Shannon airport is open, but I doubt any cargo facilities will be.

    It was 50/50 last I heard. There may be one or two more movements in SNN from what I hear.

    The rule for pilots is if it goes 60 degrees or more off runway heading then take it as full crosswind.

    You're going to have to qualify that rule with a source!

    There is a 4 knot difference in our max crosswind limit between 60 degrees and 80 degrees! That's the difference between getting the pax to their destination or diverting and inconveniencing them and adding cost to the company.

    ATC give the wind in direction and strength rounded to the nearest 10 degrees and a windspeed. If it's in limits you can land if it's not then you abandon the approach.

    I should say a safety rule of thumb. It is what I was trained to do anyway, err on the side of caution and take 60 degrees or more as full crosswind. It is not in the AIP or Rules of the Air but at least for non-commercial piloting it is what I follow.

    Not a single Ryanair in the skies this evening, how unusual is that for a Thursday evening!


  • Registered Users, Registered Users 2 Posts: 18,487 ✭✭✭✭JCX BXC


    Not a single Ryanair in the skies this evening, how unusual is that for a Thursday evening!

    At 4pm I put on the Ryanair filter, only 3 in the sky at that time. Cork had only 2 Ryanair flights today, Shannon only 3!

    Shannon's last arrival landed an hour ago (30mins early), Dublin's arrivals will be finished in about 30mins, (Last Departure scheduled for 11pm), Cork is scheduled to have the last commercial passenger arrival into Irish airspace this eve, with the LHR flight schedules for 11:15pm.

    Will be interesting to see if SNN has any traffic tomorrow.

    Might be a diversion.

    Its possible, but with how often it happens on a normal day(Maybe 1-2 a month), and with the reduced traffic on Xmas day, its unlikely.

    As above though, the TK cargo might be popping in.
