Ok, I agree with Torque 2 that this approach topic has ran its course. No offence to NWSRG but they are temporarily unsure of their position or are having a laugh, but this has resulted in everyone throwing in their view whether it be right or wrong.
Dontdo it is spot on you cant be west of the field on a track of 050 to intercept and we most certainly do not fly npa's 'manually' as he rightly corrected alacrity.
Unless Boeing have changed the seat layout since, 16F is on the right side of the aircraft which means you were south of the field to enable you to see the lights on a track of 050.
Finally this has everything to do with Aldergrove, after all it was an approach into it!
