smoothing the bumps
The real value of approach systems is giving the pilot a straight line to establish a steady approach speed and descent rate, and the last few hundred feet should be a continuation of the aforesaid straight line....almost.
I have been a spare pair of eyes during training details, and have been amused at the deviations from the norm... using glider pilot reference point techniques, I have been convinced that the driver was heading for the underground option.
Putting all the approach lights in one box can give unexpected results... the Barkston Heath boxes had to be realigned after they were used as spectator terracing during the National Model Flying Championships. I learnt a lot about grovelling. Should have got someone else to sign for the airfield.
P.S. - Station Commander wanted the little oil spots removed from the runway after the event... ever scrubbed a runway???? !!!
