Well thanks everyone ,I'm not about to justify any of my questions here.But the main point of this thread was not to ask how a NDB approach is flown in general.That was not the point nor the big difficulty, especially not with the omnipresent DME
nowadays as Cosmo Kramer was so quick to point out.
The main issue behind all this for me was, how this one done without DME, and to be
more precise how the vertical profile of the approach was flown back then and in which configuration.
I just wanted to know wether the timing was done to the effect to achieve a constant
angle descent beginning from the point where the course reversal was completed so that
you pass the SPARKS NDB and DICEY on your way down a constant 3degree descent path or if it was flown basically chop'n drop even in a DC9/727 type of AC.
Thats all.
Best regards,
John
