The FAA has revised its warning for Kenyan airspace – the area to ‘exercise caution’ is now limited only to that airspace east of 40 degrees East longitude below FL260 (i.e. the border region with Somalia). Prior to this, their warning applied to all airspace in Kenya below FL260.
Published on 26 Feb 2018, the warning maintains the same wording to clarify the type of weapons and phases of flight that the FAA is concerned about, specifically:
- fire from small arms,
- indirect fire weapons (such as mortars and rockets), and
- anti-aircraft weapons such as MANPADS.
The scenarios considered highest risk include :
- landings and takeoffs,
- low altitudes, and
- aircraft on the ground.
The updated guidance is intended for US operators and FAA License holders, but in reality is used by most International Operators including EU and Asian carriers, since only four countries currently provide useful information on airspace security and conflict zones.
The Notam uses FL260 as the minimum safe level, though we would suggest, as usual, that a higher level closer to FL300 is more sensible.

One of our primary missions at FSB is to monitor the world’s airspace and report on new risks to civil aviation. When enough changes occur, we update our “Unsafe Airspace Summary“.
Today, we published a new summary effective 16AUG2017 – version “INDIA”.
First up, the map as things stand:
Red is Level 1 – Avoid this Airspace
Orange is Level 2 – Assessed Risk
Yellow is Level 3 – Caution.
A live version of this map is always updated at safeairspace.net
What’s changed since the last summary?
- Somalia is downgraded to Level 2, so there are now five Level 1 – Avoid countries: Libya, Iraq, Syria, Yemen, and North Korea.
- Saudi Arabia is upgraded to Level 2, due to assessed risk in the southwestern portion of the FIR (Yemen border area)
- French Guyana no longer a threat as strikes and airspace closures have ended
- Addition of Japan, Venezuela and South Korea at Level 3 – Caution advised
If you have ops to any of these countries, make sure to have a read of the risk information. A full library is at safeairspace.net.

Most conflict zone guidance from Aviation Authorities is based on the risk posed by MANPADS – Man Portable Air Defence Systems, or more descriptively – Shoulder Launched Surface to Air Missiles (SAMS).
Large-Unit SAM attacks on aircraft are uncommon – MH17, removed from the sky by a Russian-made Buk missile, was the first aircraft to be shot down by a large SAM unit since a Siberia Airlines Tupolev in 2001. These large units – requiring a radar system as part of the mechanism – have never been used by terrorists. Almost all incidences involving large-unit SAMs have involved misidentification. There is no safe altitude from a large SAM.
MANPADS, on the other hand, represent a greater threat to aircraft in 2017. These shoulder-launched systems are very portable, and far more likely to fall into the wrong hands. Common ranges are in the 10,000 – 15,000 ft range. The most dangerous is the FIM-92 Stinger, which has an operational ceiling of 26,000 ft (and there is concern that these have reached anti-government rebels in Syria)
The internationally promulgated standard safe altitude for overflight has now become about 25,000 ft AGL. Most CAA/State guidance is issued based on this number. There are two important points for aircraft operators to note:
- That is 25,000 feet Above Ground Level. A missile could easily be launched from a mountain, or higher ground, so if you take 25,000 feet as your safety margin, make sure to add the terrain elevation beneath. In South Sudan, for example – Juba is at 2,000 feet – most of the country is at about this height. So 27,000 feet should be the minimum safe level, and you can work with FL270.
- This is based on the assumption that we’re not worried about Stingers. Especially in the Middle East, a higher safe altitude might be better. FL300 seems like a good place to start.
