Lets face facts here.
Khartoum is no better, nor worse, than any other African destination.
Having personally operated to KRT dozens of times with B707 and (especially) TriStar equipment, I never found it all that difficult....even when the runway was considerably shorter, and no ILS existed.
In short, you have to pay attention to what the hell you are doing...and if you don't, expect rather large problems.
ATC...not bad, by African standards.
Radar?
Can be very accurate, if the right folks are on duty.
For those crews that expect European standards with ATC...better fly somewhere else, especially during haboob season.
Sorry, them's the facts.
