NOTAM Viewer is a free web application and mobile app that allows pilots, dispatchers, and aviation professionals to search and view Notice to Airmen (NOTAMs) from the FAA and aviation authorities worldwide. It provides an easy-to-use interface with smart parsing and filtering capabilities.

A NOTAM (Notice to Airmen) is a notice distributed by aviation authorities containing information about the establishment, condition, or change in any aeronautical facility, service, procedure, or hazard. This information is essential for flight operations and safety.

Yes! NOTAM Viewer is completely free to use. Both the web application and mobile app are free with optional ads. There are no subscriptions, hidden fees, or premium tiers.

No account is required. You can start searching NOTAMs immediately without any registration or login.

Simply enter a 4-letter ICAO airport code (e.g., KJFK, GMMM, EGLL) in the search box. As you type, autocomplete suggestions will appear. Select an airport or press Enter to view NOTAMs.

An ICAO code is a 4-letter code assigned by the International Civil Aviation Organization to identify airports and FIRs worldwide. Examples: KJFK (New York JFK), EGLL (London Heathrow), GMMM (Casablanca FIR).

Yes! Start typing the airport name in the search box and autocomplete will show matching airports. For example, type "London" to see all London airports.

After searching for an airport, use the content filter box to search within NOTAMs. Type keywords like "RWY" (runway), "TWY" (taxiway), or "ILS" to filter results instantly.

Click on any NOTAM card to expand/collapse it individually. Use the "Expand All" or "Collapse All" buttons in the toolbar to control all NOTAMs at once.

Click "Show Raw NOTAM" to view the original, unformatted NOTAM text exactly as received from the FAA. This is useful for verification or copying the exact text.

Q) - NOTAM qualifier codes and classification
A) - Location: ICAO aerodrome code
B) - Start: Effective date and time (UTC)
C) - End: Expiry date and time (UTC)
D) - Schedule: Daily or recurring schedule
E) - Description: Detailed NOTAM text
F) - Lower limit: Altitude lower boundary
G) - Upper limit: Altitude upper boundary

All NOTAM times are in UTC (Coordinated Universal Time), also known as Zulu time. Make sure to convert to your local time when necessary.

FIR stands for Flight Information Region - a specified airspace region where flight information service and alerting service are provided. FIR NOTAMs apply to a larger airspace area rather than a specific airport.

A warning appears when a NOTAM doesn't follow standard ICAO format. This typically happens with domestic US NOTAMs. The raw text is always available, and we do our best to extract key information.

All NOTAM data comes directly from the official FAA NOTAM Search API (notams.aim.faa.gov). We display publicly available data in real-time.

NOTAM data is fetched in real-time every time you search. Click the "Refresh" button to get the latest NOTAMs for your selected airport.

Important: While we display official data, NOTAM Viewer is for informational purposes only. Always verify NOTAMs through official channels and approved flight planning services before flight operations. See our disclaimer for details.

This could mean: (1) There are no active NOTAMs for that location, (2) The ICAO code is incorrect, (3) The airport may not be in the FAA database, or (4) There's a temporary API issue. Try searching for a nearby major airport or FIR.
