Landing On 'wrong' Runway At LHR?

Fri Feb 18, 2005 8:36 pm

While I was in the bmi lounge in T1 recently I was watching the planes landing one after another from the East onto the southern runway. Take-offs were on the northern runway heading west.

It was around midday, and I recall that the runways used for take-offs & landings changes around this time (?). So when I saw a plane coming in to the north runway, I presumed the switch had taken place.

However, the following planes all landed on the southern runway, and take-offs continued on the northern one. So why did this one plane (Royal Air Maroc) land on the Northern one - surely length isn't a problem?

Any thoughts?

Just from watching and listening to some of the comments in the BBC's Airport series, they can request that certain services can go from (or arrive on) a particular runway to reduce taxiing time - usually flights with diplomats/royalty/heads of state onboard.

Except Royal Air Maroc landing on 27R is actually a longer taxi than if it landed on 27L (southern runway). I would suggest some kind of atc thing.

If they were on 27's, then they always switch runways at 3pm. For example, if aircraft were arriving on 27L in the morning, they will change at 3pm and use 27R for arrivals.

Sometimes when the airport isnt busy, ATC can use both runways - T4 flights like to use 27L for example as it is a shorter taxi to the terminal, while BMI flights prefer 27R as it is closer to T3.

I hope this helps.

When would LHR not be busy, except after 11pm? and why would BMI care about T3 being closer to 27R when they use T1?

Isn't the domestic gates lined up parallel to runway 27R? I suppose that's what he was referring to  Smile

Most mornings aircraft arrive onto both runways depending on when they're parking. Around 7am things usually change to either 27L or 27R when the departures pick up.
The 3pm alternation also alternates weekly ie 27L arrivals till 1500/27R arrivals after 1500 one week and vice versa the next the changeover being on Monday.
The 09's of course don't alternate arrivals always being on the R. (except in very rare circumstances).

Actually when using 09L/R it's 09L that is used for arrivals and 09R for departures (with the odd BA flight using 09R to land as it means you don't have to cross a live runway to get to T4).

09L is not used for departures due to the Cranford Agreement (I think) on noise reduction and abatement.

Feroze: correct - it is. Ironic thing is that in it's last few months of operation Concorde would only take off on 09L when they were operating 09L/R. Now if anything was going to blow the Cranford Agreement out of the water that was it!! Bet that rattled a few roof tiles!  Big grin

09L had to be used for Concorde due to the construction work at the end of 09R which meant aircraft could not use the full length of the runway.

Planesarecool: you are correct, however what TimRees was talking about was which runway is used for departures and which for arrivals when using the 09s.

The reason you saw one use the "wrong" runway is called TEAMING i believe. It inceases the arrival rate when there is less traffic to depart and makes better use of the runways i believe its done 2-3 times an hour
