Back to the remote deicing facilities.
I think Hel has about 8 at each of the thresholds of 04R and 22R so say 16 in total.
No doubt someone knows the exact figure.
Now from the above figures LHR has approx 3 times the no. of movements.
By my reckoning LHR would need about 3 x 16, say 40 to be kind, remote deicing stands, 20 at each threshold, to offer a similar service.
That is a fair bit of real estate and associated taxiways.
As a point of interest.
According to the tv this morning there is chaos at the airport, there were not enough hotel rooms last night and the people are very angry at the lack of staff and information.
But, hey, this is Finland, it is not like it doesn't happen often!!
I have come to the conclusion that, wherever you are, the weather is unbeatable sometimes!!
