South Sudan

Risk Level: Two - Danger exists

[ about risk levels ]
Following a military coup in neighbouring Sudan in April 2023, Sudan remains closed to all civilian flights, and in South Sudan, air navigation services remain suspended above FL245.

In South Sudan itself, following five years of civil war, a ceasefire has largely held since Sept 2018. Significant reduction in violence, but the political and security situation remains volatile. In the event of a serious deterioration, similar to those of July 2016 and Dec 2013, HJJJ/Juba airport may be closed at short notice. The UK, France and Germany still advise against overflying South Sudan below FL250/260 due to the risk posed by anti-aircraft weaponry. The US published a similar warning but rescinded it in Aug 2019.

The primary risk now comes from no ATC above FL245 due to the military coup in Sudan, and poor levels of ATC provision for overflights below FL245 or for aircraft operating to HSSJ/Juba airport. In Jan 2021, ICAO published a letter warning of service disruptions and lack of qualified ATC personnel, the lack of contingencies in place, communication issues, the number of withdrawn navigation aids and above all, the lack of information being supplied to operators regarding these issues.

Major events:
April 2023: Military coup in Sudan on Apr 15. Sudan’s airspace closed, South Sudan’s airspace closed above FL245.
April 2019: Military coup in Sudan led to the temporary closure of South Sudan’s airspace.
June 2016: The South Sudanese army declared intention to shoot down aircraft without permits and/or not following proper procedures.
