Airports with highest average approach speeds
Does anyone have a list of the top 10 airports by approach speed? I’d be curious to see what airports rank highest.
Re: Airports with highest average approach speeds
I would venture a guess and opt for high altitude airports, some of the Chinese himalaya airports
or the likes of La Paz SLLP airport in Bolivia at 13000-ish feet.
IAS might be the same but groundspeed (wheelspeed) will be considerably higher than at sealevel.

MEX ?

Re: Airports with highest average approach speeds
It all depends on what you mean by "speed".
As far as an aircraft is concerned its speed relative to the air is always the same. The indicated speed at FL350 differs little from the indicated speed at 5000ft, but because of the much lower air density the speed above ground is very different.
Essentially, pitot tubes measure the amount of air particles that enter the tube (simply put). As such, lower density means a higher ground speed whilst the indicated speed on the flightdeck is always the same.
If we are talking ground speed I would be looking at high altitude airports that get heavy traffic from freighters. Especially the 747.
If we are talking indicated speed it gets more complicated.
I fly in Europe so I don't know about other parts of the world, but there are a number of airports here that require us to keep a minimum speed of 160kts until 4 miles from the runway. At the airport where I am based we have to fly 210kts until 12 miles, then 190kts until 9 miles and then keep the 160 until 4miles. At that point we pull the speed back and hope that by 800ft we are fully established in terms of speed, otherwise it means go-around.
Those kind of airports will definitely have higher approach speeds than those that allow pilots to select their own speed on the ILS.
I hope this makes a bit of sense. Just came back from a night flight, so I am very tired, but I thought I would try to explain.
The question of "what speed are you guys flying?" often comes up when talking to people, and it is not very easy to answer. There is the Mach number, RAM effects, etc...

Re: Airports with highest average approach speeds
Might LCY with its steeper-than-normal approach gradient be up there, or is it offset by the specialist aircraft types that frequent it?
