Risk Level: One - Do Not Fly

[ about risk levels ]
Yemen is an active conflict zone. A civil war which began in 2014 has developed into an international conflict. There is a high risk to civil aircraft. The vast majority of Yemeni airspace (OYSC/Sanaa FIR) should be avoided. The US, UK, France and Germany all prohibit aircraft from overflying any land portion of the FIR. US operators can still use UT702 and M999, while UK and German operators can use over water portions of N315, UL425 and R401 with limits as published by Notam (all well off the coast). Saudi Arabian airspace to the north and Somali airspace to the South also have risks.
The primary risk is intentional targeting by terrorist groups with access to sophisticated anti-aircraft weaponry. Civil aircraft may also be at danger from on-going high intensity military operations including the use of explosive drones and missiles. Saudi-led airstrikes can occur at any time with little regard to civil traffic, including in the capital Sana’a.
Major events:
2020-2022: Ongoing Houthi drone and rocket attacks targeting OEAH/Abha and OEGN/Jizan airports along the Yemeni-Saudi Border.
July 2018: Houthi target OMAA/Abu Dhabi Airport with explosive drones.
April 2018: Saudi airstrikes on Sana’a in retaliation for Houthi drone attacks across the border.
2017: OYSN/Sanaa Airport badly damaged by coalition airstrikes.

From 04/11/2021 and until further notice, pilots in command of aircraft performing air services mentioned in paragraph 1.1 are requested not to penetrate into the airspace of Yemen (OYSC FIR (SANAA), except for routes located in the maritime part of FIR OYSC (SANAA), east of route B400 included, on which a flight level above or equal to FL320 is requested to be maintained at all times.

Level 2 (Recommendation)
As of February 9, 2021, and until further notice, Canadian Air Operators and owners of aircraft registered in Canada are advised not to enter the airspace of Yemen (Sana’a FIR (OYSC)) northwest of the line created by the waypoints PAKER-ORBAT-NORMA on jet route UT702, due to potential risks from dedicated anti-aviation weaponry and Remotely Piloted Aerial Systems operations.
Source: USA
Reference: SFAR 115
Issued: 11-Dec-19, valid until: 07 Jan 2025
Plain English: US operators are prohibited from overflying the OYSC/Sanaa FIR north of a line KAPET-NODMA-ORBAT-PAKER-PARIM-RIBOK (i.e. the landmass). The US FAA specifically mentions UT702 and M999 offshore routes as being ok to use.
The FAA continues to assess that opposition elements in Yemen do not possess functional medium-/long-range strategic SAM capabilities or control territory from which surface-to-air weapons possessed by those opposition forces are capable of reaching air routes off the southern and western coasts of Yemen. Therefore, the FAA maintains without change the boundaries of its prohibition on U.S. civil aviation operations in the specified areas of the Sanaa FIR (OYSC). Operations on jet routes UT702 and M999 continue to be permitted.

Therefore, as a result of the significant continuing risks to the safety of U.S. civil aviation in the specified areas of the Sanaa FIR (OYSC), the FAA extends the expiration date of SFAR No. 115, § 91.1611, from January 7, 2020 until January 7, 2022. By this action, the FAA prohibits flight operations in the specified areas of the Sanaa FIR (OYSC) at all altitudes by all: U.S. air carriers; U.S. commercial operators; persons exercising the privileges of an airman certificate issued by the FAA, except when such persons are operating U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except when the operator of such aircraft is a foreign air carrier.
