Sudan ATC
Khartoum ATC has SSR but the systems is often unservicable.
Reports from fellow pilots in Sudan, say that no squawk codes were given that morning and Khartoum APPROACH control was not using the radar. All aircraft had start clearances delayed for 30-45min and others were left at holding points to wait, while ATC was trying to contact the A/C.
It is an unfortunate incident, air accidents are not uncommon in this part of the globe but hopefully this will be a wake up call for the Sudanese ATC authorities, who need to improve the performance of the MAJORITY of their controllers and systems they currently have in place.
