The old salt Russians. Dual ADFs on RMIs.
Was there any calibration flown on the approach?
Only Iran knows that.
Even more exciting would be flying a missed from as much as 4000' below the MDA. Was calibration for the missed flown from just above the runway?
That might not be part of Iranian flight inspection specs. Or, many other countries for that matter.
I believe the recent installation of the VOR/DME is evidence that Iran was on the path to improvement at this difficult airport.
