Heathrow TOGA
Watched the BA from Munich go around on Friday night ( around 20:00) into Heathrow. Preceeding aircrafr missed the turn-off and departed active runway late.
Made me think- does anyone know how many go-arounds' at Heathrow every day / week due to aircraft departing runways' late?

A TOGA is a switch/button on the throttles, not a procedure.
If you mean the number of GA's then there is a formulae......
No. of GA's = No. of approaches minus No. of landings achieved from those approaches

That's not been my experience, paddy_22002. I can't say that when we do 2.5 miles spacing (which is really not that often), the MA rate goes up, because we only do it when we've got good conditions.

I may just be unlucky then!
I have averaged 1 MAP every year in LHR since operating on Shorthaul in the last 6 years. In the previous 10 on long haul I only had 1.
With regards to the conditions required for 2.5 spacing they are prescribed but not always adhered too. For example how often have you heard Windshear reported on the last mile of approach on 27R and the 2.5 spacing dropped? Not a complaint from me though. I'd rather that than another 15mins in the hold.
For what its worth I do not think that there is any compromise to Safety standards and believe a lot of other Airports could operate to similar separtion standards when required to increase runway capacity and improve Airline schedules.

It must be me.
From a presention by the Heathrow Devlopment Manager;
Go-aroundsTypical go-around rates at Heathrow
Of the order of 50 per month (1-2 per day)Normally only 1-2 per month due Wake Vortex

When ATC talk about 2.5 mile spacing, we mean 2.5 miles apart out at 6 miles or so on the approach, not inside 4DME.
Normal spacing is 3 miles, which of course means that when no.1 touches down, no.2 is going to be maybe 2-2.5 miles behind due to the catch up. There's also the fact that FIN (120.4) will be aiming for 3 miles, but 2.5 is legal, so sometimes due to many factors you'll have less than 3 miles without it being intended.
Personally I've never heard of 2.5 mile spacing being on and windshear either reported or forecast. A few months ago the conditions for 2.5 mile spacing were relaxed. However, we don't promulgate the fact that we are doing 2.5 mile spacing to anyone.

2 in one week on my last week on the 737. Both really as result of the 737 higher approach speeds v 757 or light Airbus.
2 on the 757 due to slow preceding traffic vacating the r/w. 2 on the 767, 1 because of wx and the other slow vacating company traffic on 09R. That one a little annoying!
