[Please see two updates below.] Many crucial questions about the tragic/disastrous apparent shootdown of the Malaysia Airlines flight in Ukraine are still unanswerable. Who did it? Why? With what warning? Or repercussions?
But at this point one question can be answered: Did aviation authorities know that this was a dangerous area?
Yes, they most certainly did. Nearly three months ago, on the "Special Rules" section of its site, the U.S. Federal Aviation Administration put out an order prohibiting American pilots, airlines, charter carriers, and everyone else over whom the FAA has direct jurisdiction, from flying over southern parts of Ukraine.
Here is how the "who this applies to" part of FAA NOTAM 4/7677 looked, in the ALL-CAPS typeface of many FAA communications and in the language the FAA uses to say "this means YOU!"
THIS SPECIAL FEDERAL AVIATION REGULATION (SFAR) APPLIES TO THE FOLLOWING PERSONS:
1) ALL U.S. AIR CARRIERS AND U.S. COMMERCIAL OPERATORS;
(2) ALL PERSONS EXERCISING THE PRIVILEGES OF AN AIRMAN CERTIFICATE ISSUED BY THE FAA, EXCEPT SUCH PERSONS OPERATING U.S. REGISTERED AIRCRAFT FOR A FOREIGN AIR CARRIER; AND
(3) ALL OPERATORS OF U.S. REGISTERED CIVIL AIRCRAFT, EXCEPT WHERE THE OPERATOR OF SUCH AIRCRAFT IS A FOREIGN AIR CARRIER.
And here is how the "these are the areas to stay out of" part of the order was written, everything specified as Longitude/Latitude coordinates:
(D), NO PERSON DESCRIBED IN PARAGRAPH (A) MAY CONDUCT FLIGHT OPERATIONS IN THE PORTION OF THE SIMFEROPOL (UKFV) FIR WITHIN THE FOLLOWING LATERAL LIMITS: 454500N 0345800E-460900N 0360000E-460000N 0370000E-452700N 0364100E-452242N 0364100E-451824N 0363524E-451442N 0363542E-451218N END PART 1 OF 4. 23 APR 22:30 2014 UNTIL 1504270001. CREATED: 23 APR 22:16 2014FDC 4/7667 (A0012/14) - null AIRSPACE SPECIAL NOTICE UKRAINE 0363200E-450418N 0363418E-445600N 0363700E-443100N 0364000E-424400N 0361600E-424700N 0340000E-424800N 0304500E-434100N 0303200E-441500N 0302400E-444600N 0300900E-455400N 0322500E-454900N 0324700E-455400N 0330600E-455600N 0332700E-455900N 0332900E-THEN ALONG THE CRIMEA BORDER TO 454500N 0345800E.
Until only a few years ago, most FAA notices—of restricted air space, of special weather hazards, of other areas-of-concern—were promulgated in this same indecipherable Long/Lat form. Now the FAA distributes most information on U.S. airspace via easily understandable graphical overlays. For instance, its Special Use Airspace site, which you are supposed to check before every flight, gives you a color-coded illustration of all active military airspace, restricted zones, etc, at any given time. Here is how part of it looks right now, mainly showing active "Military Operations Areas" in the South. This is a screen shot, but on the real map you can click on each one to see its vertical limits. For instance, those large ones over northeastern Mississippi go from 8,000 feet upward, so we were able to fly under them in our recent visits to the "Golden Triangle" cities in the same area.
I have not yet seen a map that plots the Long/Lat points of the Ukraine no-fly order onto the route the Malaysian plane flew, and where it was apparently shot down. When I learn of one, I will provide an update. (Credit to Jad Mouawad of NYT for seeing this notice before I did.)
UPDATE This FAA notice appears to apply mainly to Crimea and the areas immediately to its north, all of which are south of the reported crash zone. So this rule would apparently not have prevented flights over the exact area of the crash, but it certainly was a sign of a general trouble zone. Thanks to Joel Koepp and other readers for plotting out the Long/Lat readings.
The point for the moment: the FAA "Special Rules" section tells U.S. pilots and aircraft not to fly over trouble spots ranging from North Korea to Yemen to Syria to Iraq. And since last April it has told them not to fly over certain parts of Ukraine.
Update-update Thanks to readers who have pointed me to another, later NOTAM, which warned planes about hazards in broader areas of Ukraine, apparently including those the Malaysian airliner flew across. The hazard this NOTAM warned against was possibly conflicting Air Traffic Control instructions from Russian and Ukrainian controllers. A sample of that NOTAM is shown below, with text here.
