This outage is due to department of defense GPS interference testing taking place 17-18 Nov 2015. The interference generated may make the GPS signal unreliable and the outage cone described by NOTAM lets you know that you can't trust the GPS signal during this time. This interference may be purposeful jamming or live testing of devices that may interfere ...

For the solar eclipse of March 20, 2015, I found this example below, seems like it's the opposite of a warning. E) A SOLAR ECLIPSE WILL TAKE PLACE ON THE 20TH OF MARCH. SPECIAL ROUTES HAVE BEEN DEFINED FOR FLIGHTS PLANNING TO VIEW THE ECLIPSE. THE ROUTES ARE DEFINED AS FOLLOWS: (...) ANY ADDITIONAL REQUESTS FOR A SOLAR ECLIPSE PROFILE SHALL ...

Here is a view of 05/23 at CRW: Source: Google Maps At either end of the runway there is a large drop off, here is another view: Source: WVGazetteMail.com (In March of 2015, the EMAS at the approach end of 05 was destroyed in a land slide as shown in the picture above, I cannot find a picture if it has been repaired, the NOTAM date indicates that it has ...

When I have had to file NOTAMs for skydiving demonstration jumps, I just called AFSS (1-877-4-US-NTMS) and asked to file. The folks at Lockheed are way more helpful than the Feds used to be and will walk you through the process, but it is still good to have your information together before you call. At a minimum you need a description of your activity, ...

Is there a NOTAM or a temporary flight restriction associated with laser ranging activity? Apparently yes: The lasers on the telescopes are in the range of 15-40 watts. The FAA calls a no-fly zone over the area when a laser is in use, and two people have to stand around outside in the freezing temperatures and watch for airplanes. Each of them has a kill ...

The FAA has no authority over roads, bridges or any other public roads. Usually, it's the the event organizer who's responsible for requesting and coordinating road closures; think of triathlons, parades etc. And even without the FAA, there are very good reasons for the local police to close the bridges: rubbernecking and accidents caused by distracted ...

The NOTAM format is from the time when people still would call the value of individual bits over a phone line. Ok, that may not have happened, but my point is that data transfer was incredibly slow compared to current day standards. Therefore a compact format saved significant transmission time and cost without losing any information. The format didn't ...

What, you dislike the fact that the NOTAM about patchy ice is patchy in its detail? :) Generally if you need more information about a NOTAM (in the US) you can check with: Flight Service While collecting your briefing ask if they have any more detail -- sometimes they do, sometimes they don't, but it's worth asking. A local FBO Particularly for FICON ...

14 CFR 105 covers parachute operations in the USA. There is not a requirement for a NOTAM, but since this happened at an uncontrolled airport the nearest ATC facility must be notified at least 1 hour in advance but not more than 24 hours in advance and, they must have approval from airport management. Then for the actual jump, ATC must be notified at least ...

Multi-part NOTAMs seem to be part of ICAO standard, as far as googling reveals. I can’t seem to find a definitive reference though. An example - and from experience a relatively reliable one - for a multi-part NOTAM is the infamous Sydney crane list, at time of writing in NOTAM H6002/18, which at the moment comes in three parts and has the part listing in ...

The FAA definitely has problems with the bridges. They don't have authority to close bridges, but they do have authority to refuse the waiver contingent upon things they feel are not safe. It started while the bridge was under construction. They almost didn't approve the waiver due to the cranes. Apparently they were satisfied when the fire dept was able ...

It means exactly what it says. The ILS is out of service, so you can't use it. An ILS can consist of several different elements, for example localizer, glidepath, DME, inner/middle/outer markers as well as a bunch of technical monitoring equipment, ATC control panels, warning systems and backup power supplies. Should any of these components fail, it may be ...

By your description a "military" Chinook-type helicopter was flying at high speed over a congested area at about 100 ft AGL. The answer to your title question—Under what conditions would a helicopter be allowed to fly at low altitude over populated areas?—is twofold. Firstly, under FAA regulations (more on this in a moment), helicopters are not generally ...

I have no idea about the specific flight you saw, but the general answer to your question about operating legally below the minimum safe altitudes in 14 CFR 91.119 is that the FAA can grant a waiver allowing lower flight. The waiver process says that to get a waiver to 91.119(b) (flight over congested areas) there must be a public interest reason but ...

I'll provide information for the US airspace. However many countries, ICAO members, will have similar concepts and procedures. Short answer You are not required to follow any procedure for entering a warning area or an inactive restricted airspace. In the latter case, you need to ensure the area is actually inactive. A safe practice is to contact the ...

I feel there is more to say than currently answered, feel free to reuse part or all of this content to build an improved answer which could be selected. There are recaps of flight restrictions, e.g. French DGAC publishes maps and plain text files recapitulating areas, in addition of individual NOTAMS: Source: DGAC ICAO announced in 2015 the creation of a ...

In the case of the 777 (or any flight operating on an IFR flight plan) it is ATC's (and the pilot's) responsibility to vector the flight around restricted airspace. In the event of pop-up NOTAM's, ATC will do their best to inform you, especially on an IFR flight plan. The key is you should be talking to somebody, or at least listening in. I have a feeling ...

FICON is outlined in FAA JO 7930.107 "FICON REPORTING". FICON is the "FIeld CONditions reporting. It identifies information that used to be called "braking action", but is now a little more succinct. The conditions for the runway are reported in thirds, [First Third]/[Middle Third]/[Last Third], with the following data outlined on page 6: So 5/5/5 means ...

If the NOTAM duration is expected to return to service prior to the End of Validity time, the time is expressed by using a date-time group followed immediately by EST (estimate). Any NOTAM that includes an EST must be canceled or replaced before the NOTAM reaches its End of Validity time. If the NOTAM is not canceled or replaced, it will expire at the end ...

No, the FAA does not have the authority to close a bridge, roadway, or other general public item outside of an airport or airspace. The appropriate regulations are 14 CFR 91.303 Aerobatic flight. No person may operate an aircraft in aerobatic flight-- (a) Over any congested area of a city, town, or settlement; (b) Over an open air assembly of ...

For SUA NOTAMs, you can find it via sua.faa.gov, in either map or text format. If an SUA on a chart has defined hours, stick to those. Example after downloading the text data: Map example (layer control is useful): Color indicates if active or scheduled and how far in the future.

The Notice to Airmen Publication is an FAA publication, currently available in PDF or print form, published every 28 days. The NTAP contains airway, airport, facility, procedural, general, and international NOTAMs. As voretaq7 notes, this includes long term NOTAMs that a flight service brief won't include if you don't ask. There is also a section with ...

ICAO is offering a very nice API for retrieval of, for example, aerodrome names/ICAO codes and NOTAM's. It is currently in public beta, which means that it is free to use. Once they finish testing it, there will be some kind of cost involved, but they have not published any pricing details yet. You can find it here: https://www.icao.int/safety/iStars/Pages/...

Actually it doesn't have anything to do with voice capabilities: 5-3-5. UNMONITORED NAVAIDs a. All VOR, VORTAC, and ILS equipment in the NAS have automatic monitoring and shutdown features in the event of malfunction. Unmonitored, as used in this order, means that the personnel responsible for monitoring the facility have lost aural and visual monitoring ...

Short answer: D NOTAMs are about airports and navigation facilities; FDC NOTAMs are about airspace, procedures or regulations; and L NOTAMs don't exist any more (unless you're in the military). The information on NOTAM types is a bit messy and inconsistent, to say the least. The Alaskan FSS lists 11 types; the PHAK 13-3 lists 3 types (as acpilot mentioned ...

1 - It's always been done that way. 2 - You'd be surprised how many government computer systems are still using ancient hardware and operating systems.

As I understand your question is mainly about line E of a NOTAM, right? Well, this one is in fact meant to use 'plain' English language, in contrast to all other lines, where location and reach as well as type and urgency and duration is encoded. Just, as it already has been mentioned, NOTAMs originate in a time when transmission speed was unimaginable slow ...

I live in the totality path (totality occurred here about 45 minutes ago.) I don't see NOTAMs for the eclipse at any of the nearby airports, including one whose runway is about 1 mile from the center of the totality path. While NOTAMs may be issued for traffic purposes as ymb1's answer points out, it seems that there's no general requirement for a NOTAM to ...
