    It usually departs on the BPK departure, sometimes a DVR

    Fixed wing a/c can transit LL under SVFR, no problem. Of course, the definition of SVFR includes the phrase “not to hinder IFR traffic”, which would be the case if there were other a/c around at the time.

    With this in mind, if ‘simultaneous parallel approaches/take-off’s’ were to be introduced at LHR, would this increase the number of ‘slots’ because in effect you are having two aircraft taking off quicker than at present by using just one runway for take-off’s and the other for landings, or is it not as simple as I am thinking?

    You’re really getting into Mixed Mode there, and that’s a whole new can of worms. To do parallel departures, you need decent weather, of course, and you can only do it with a/c on diverging tracks….I’ve done it a few times late at night and during the only quiet day of the year, Christmas day. It’s a bit dangerous to have a southbound rolling off 27R the same time as a northbound off 27L.

    Mixed mode will increase the runway movement rates by about 10-15%, but because the airfield is short of stands, it will not mean, at least for a few years, any more slots, merely to improve the resilience of the airport in delay situations.

    Mixed mode is horrifying to see on GMC, though.

    09R has no high speed turn offs, so aircraft vacate the runway more slowly then the other runways at Heathrow, especially if they’re vacating to the south of 09R. Our ‘rule of thumb’ is for 6 miles spacing when doing 1 in, 1 out on 27R, 27L and 09L, but 7 mile spacing for 09R.

    Yes, we are able to do simultaneous parallel approaches (i.e. a/c both 5 miles out on 27L, and 5 miles out on 27R), but the aircraft need to agree to maintain visual separation with each other, and that needs to exist at all times where other separation (radar or vertical) does not, so in practice it is rarely used. To be used effectively, you’d need two separate Final Director frequencies, and the danger comes where you are pointing a/c at each other on the closing heading, with a very small time window to recover if one of them fails to capture the localiser and sails straight on.

    Adam, no that’s not the case.

    Just a few days ago when we were easterlies I took quite a few inbounds on my runway (09R) for no particular reason other than it’s a challenge and makes things more interesting for me as an ATCO…Especially given that 09R is a horrid runway to operate in mixed mode

    There is no restriction on landing runway on easterlies.

    TEAM stands for Tactically Enhanced Arrival Method, where if the inbound delays reaches a certain level, we are permitted to land 6 a/c an hour on teh departure runway. This is only usually used on westerlies…..on easterlies if it’s getting a bit busier inbound we might just land one or two on 09R to head off the build up of delays when they’re predicted to grow, before we get into the official criteria for TEAM…a course which is not available to us on westerlies, when we have to just sit there and wait until the delay trigger is reached.

    We need defined reasons to land an a/c on the departure runway on westerlies, but we actually need no reason at all to land on 09R.

    ‘Because I felt like it’ is equally as valid as any other. 🙂

    There’s nothing at West Drayton anymore. I believe there is an RAF standard flying at Swanwick, if I remember correctly.

    I doubt it will be up for long. The RCA will be along shortly, I’d imagine.

    They tend to use 303 at the moment, which if you’re talking about the visitor centre on the north side is not visible. The A380 stands 301-307 are on the south of the central terminal area.

    If using 27L / 27R for departures, all B.A. flights leaving T5 will have a very long taxi to the departure runways where lots of other aircraft will be waiting to depart

    Just the same situation for any T1 outbound taxying round for 09R departure, and that’s been going on for years.

    In fact, for 27R, the long haul a/c out of T5 will have a shorter taxy time than from T4…no runways to cross now.

    Regardless, airline delays stats are compiled from the pushback time, not airborne time.

    EGKK is SIA’s preferred UK alternate (obvious really, it allows them to carry less fuel, and the tow bar can be driven down from EGLL in little over an hour).

    Most large airfields in the UK can handle the A380 physically, but as a passenger carrying aircraft the main show-stopper is firefighting category (requires category 10, only LL has that at the moment).

    Please do bear in mind that eyewitnesses are notoriously unreliable, even ‘airport workers’ including the police and others.

    Those of us who saw what happened and were involved with it in a professional capacity know that most of what is being quoted in and by the news channels is complete tosh.

    We will be waiting for the official report.

    I’d just like to say that my colleagues in ATC and the emergency services, and of course the crew above all others performed magnificently.

    If it’s done above 10,000ft, none of it will touch the ground, it will evaporate into the atmosphere.

    Even down to a few thousand feet, very little (or any, if it’s pretty warm) will reach the ground.
