100% - thanks for that info. As one who has not had the option to fly such an approach, 4 questions if you would?
1) It appears that although you would be 'watching' the threshold NDB on the HSI you are not really flying an 'NDB' approach. What is the SOP should this ADF needle drift off, say 10 degrees as you approach MDA? Do you follow your FMC, correct to the needle or g/a?
2) On the basis that you are not actually flying an NDB but something generally more accurate, would you use the NDB MDA or a lower and is this sort of an approach called an 'NDB ' approach?
3) There seems to be a suggestion that this approach is neither approved or used by Afriqiyah. This would appear to be the case as I cannot see any other reason for the crew to have been flying what appears to be a VOR approach which is offset. What would your airline expect on 09 at TIP?
