When following this route, aircraft arrive at 90 degrees to the river Thames at Vauxhall Bridge, which is a compulsory VRP.
Not sure I quite understand this - forgive me if I'm missing something - but Alexandra Palace is pretty much due north of Vauxhall Bridge. The Thames heads approximately NNE from Vauxhall Bridge. So how do aircraft arrive at 90 degrees to the river at Vauxhall Bridge?
Heading directly from Alexandra Palace to Vauxhall Bridge wouldn't you already have intercepted the Thames somewhere further North (e.g. near Waterloo Bridge?).
