Unfortunately, LTN is not an impressive airport at all. From today’s stats each of those departures will run on average nearly 20 mins late.
Whilst the airport layout does not help, and I accept there are external factors like Northolt departures which throw a spanner in the works occasionally LTN is still a slow and ponderous operation. From basics such as late Marshallers leading to blocked taxi ways, to the “mandatory hectopascal” read back which the rest of Europe don’t require, LTN needs a thorough revamp of procedures. From the simple things like straight or 45degree push backs to auto frequency changes and getting DCL sorted for northbound departures to name but a few.
The new gates on the East apron mean that 7 stands will be blocked as soon as one aircraft moves due to no thought given to allowing a double width access and let’s not even talk about the new improved airport road access or the inadequate immigration hall.
