Iran

Risk Level: One - Do Not Fly

[ about risk levels ]
Following the shoot-down of Ukraine Int Airlines flight 752 over Tehran in Jan 2020, several countries issued airspace warnings for Iran, including: the UK, Canada, Germany, and France. The US has issued an outright flight ban, but all the others advise against landing or overflying the country at the lower flight levels. The airspace adjoining the Tehran FIR is also at risk: Iraq, Afghanistan and Pakistan.

The primary risk is a misident by Iranian air defense systems. Iran has shown willingness to use long-range, advanced anti-aircraft-capable weapons during heightened tensions and in close proximity to heavily flown international air routes. There is also a potential for Iranian surface-to-surface missile fire from western Iran, targeting terrorist positions in Iraq. More info: Iran Airspace Update, Nov 2021 (OPSGROUP article)

The secondary risks come from ballistic missile test launches with no warning by Notam, GPS jamming (including in overwater airspace over the Persian Gulf and the Gulf of Oman), and GPS spoofing. In Sep 2023, OPSGROUP received several reports of enroute aircraft being targeted with fake GPS signals, leading to complete nav failures. This type of GPS spoofing has not been seen before – IRS is quickly “infected” by false position. Suggested Guidance and Procedures, and original crew reports, in Briefing PDF here: Iraq GPS Spoofing, Sep 2023 (OPSGROUP article)

Major events:
Feb 2024: Report of GPS spoofing on airway M701 from ENEDA to NAGRO - the closest airway to Iraqi airspace. One GPS showed no position and the remaining GPS and all 3 IRS showed radically different positions.
Jan 2024: Pakistan launched retaliatory air strikes into southeastern Iran, after Iran carried out strikes in Pakistan the previous day.
Sep 2023: Several reports of GPS spoofing in northern Iraq, plus some in northern Iran.
Jul 2023: Four countries took Iran to the UN court over the the shootdown of UIA flight 752 over Tehran in Jan 2020. Part of their allegations were that Iran has still not provided sufficient evidence that measures are now in place to prevent this kind of incident from happening again.
Jan 2023: Lufthansa temporarily suspended all flights to Iran as a precaution, after an Israeli drone attack on a munitions factory located near the central city of Isfahan.
Jan 2020: Iranian Armed Forces shot-down Ukraine Int Airlines flight 752 over Tehran, having mistaken the aircraft radar return for an inbound missile. Just hours prior to the shoot-down, the US FAA issued “Emergency Order” Notams banning all US operators from overflying the airspace of Iraq and Iran. This was in response to an Iranian missile strike on US military bases in Iraq, which had occurred earlier that night.
June 2019: Iran shot down a US military unmanned aircraft operating in airspace over the Gulf of Oman with a SAM system.
Since 2017: Iran has conducted multiple ballistic missile test launches without issuing any Notams to warn civil operators, the latest taking place in late December 2019.

Plain English: US operators are prohibited from overflying the OIIX/Tehran FIR due to the risk of misidentification, and unannounced military activities in the region.
This action extends, for an additional two years, the prohibition against certain flight operations in the Tehran Flight Information Region (FIR) (OIIX) 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. The FAA finds this action to be necessary to address continuing hazards to persons and aircraft engaged in such flight operations. The FAA also republishes, with minor administrative revisions, the approval process and exemption information for this Special Federal Aviation Regulation (SFAR), consistent with other recently published flight prohibition SFARs.
