About RelevantNOTAM

On July 7, 2017, Air Canada 759 was cleared to land on runway 28R at San Francisco at night. Runway 28R's parallel runway, 28L, was closed with its lights off. The flight crew missed that one NOTAM from their 27-page briefing package. Thinking that runway 28R's lights were 28L's, the flight crew lined up with taxiway C, where there were four other aircraft, totalling over 1000 people, waiting to depart.

Fortunately, the quick actions of a pilot on the ground prevented any accident, however, the root cause behind this issue hadn't been fully fixed.

Until now.

1. You enter the flight: departure and destination airports, times, aircraft, and equipment.
2. Live FAA NOTAMs are fetched for both airports.
3. RelevantNOTAM scores each NOTAM using LLM-powered reasoning with a comprehensive context of the flight's conditions.
4. In under 3 minutes, you get a briefing of all NOTAMs, ranked from most to least important, with the affected areas drawn on a map.

Every NOTAM gets one of five tiers:

CRITICAL

Something your arrival or departure depends on is out.

OPERATIONAL

It changes how you fly this flight.

AWARENESS

It’s worth knowing, but it asks nothing of you.

LOW

It doesn’t bear on this flight.

UNPARSED

It couldn’t be analyzed, so it appears with its original text.

Each NOTAM has a short title and a plain-English reading beside the original text. The airport map highlights closed runways, taxiways, and obstacles. Every fetched NOTAM is in the briefing, including the ones that rank low.

You can pin a NOTAM to keep it at the top of the list, or report one that looks wrong. Each completed briefing is saved to your account, so you can reopen it later.
