Hey there!
If you’ve ever heard pilots talk about “NOTAMs” and wondered what they’re all about, you’re in the right place.
NOTAMs might sound like a fancy pilot term, but they’re just notices that help keep planes safe.
Whether you’re a future pilot, an aviation fan, or just curious, let’s break down what NOTAMs are, why they’re a big deal, and how they work—in simple words.
Plus, we’ll use tables to make things crystal clear!
Quick Takeaways
- What’s a NOTAM?: A notice that warns pilots about changes or dangers, like closed runways or tall cranes.
- Why It Matters: NOTAMs help pilots avoid surprises that could make flying unsafe.
- Recent News: The NOTAM system had issues, but a better version is coming in 2025.
- For All Pilots: From beginners to pros, everyone checks NOTAMs to stay safe.
What Is a NOTAM?
Imagine you’re a pilot, ready to fly.
You’ve checked your plane and the weather, but what if the runway is closed or there’s a new hazard nearby? A NOTAM, or “Notice to Airmen,” is like a quick text message from aviation authorities, like the Federal Aviation Administration (FAA), telling pilots about essential updates.
These notices ensure pilots know about anything that could affect their flight, keeping everyone safe.
Here’s what NOTAMs might tell pilots about:
| What’s Covered | Example |
|---|---|
| Runway Issues | Runway 5 is closed for repairs. |
| Navigation Problems | A radio signal tower is broken. |
| No-Fly Zones | A temporary ban over a football game. |
| Nearby Hazards | A tall crane near the airport. |
Without NOTAMs, pilots could run into big problems, like trying to land on a closed runway.
That’s why they’re a must-check before every flight.
Why Are NOTAMs So Important?
Flying isn’t like driving—you can’t stop if something goes wrong.
NOTAMs are like a pilot’s safety checklist, giving them the latest info to avoid danger.
For example, missing a NOTAM about a closed runway could lead to a risky landing.
Or flying into a no-fly zone by mistake could cause serious trouble.
A real-life scare happened in 2017 when an Air Canada plane almost landed on a taxiway in San Francisco because the pilots missed a NOTAM about a closed runway.
It was a close call that showed how vital NOTAMs are (Wikipedia – NOTAM).
The FAA also requires pilots to check NOTAMs before flying. This rule is based on Federal Aviation Regulation 91.103, which states that pilots must have “all available information” about their trip.
Skipping NOTAMs could mean trouble with the FAA and unsafe flying.
| Why Check NOTAMs? | What Could Happen If You Don’t? |
|---|---|
| Avoid closed runways | Try to land on a blocked runway. |
| Stay out of no-fly zones | Fly into restricted airspace. |
| Know about hazards | Miss a crane or other danger. |
| Follow FAA rules | Get in trouble with authorities. |
A Quick Look at NOTAM History
NOTAMs started in the 1940s as part of global aviation rules.
They were like short notes to keep pilots updated.
At first, they were called Notices to Airmen, but in 2021, the FAA changed it to “Notices to Air Missions” to include drone pilots and others.
In February 2025, they switched to “Notices to Airmen,” which got people talking online.
The system hit a rough patch in January 2023 when it crashed, stopping thousands of U.S. flights—the first time since 9/11.
The issue? Old tech from the 1990s couldn’t handle the load.
People on X were surprised at how outdated it was.
The good news is that a new, modern NOTAM system will be available in September 2025 to fix these problems.
| NOTAM Timeline | What Happened |
|---|---|
| 1940s | NOTAMs started as simple pilot alerts. |
| 2021 | Name changed to Notices to Air Missions. |
| 2023 | System crashed, grounding U.S. flights. |
| 2025 | Name back to Notices to Airmen; new system planned. |
How Do Pilots Find NOTAMs?
Thanks to modern tools, pilots have a few easy ways to check NOTAMs.
Here’s how they do it:
| Method | How It Works |
|---|---|
| FAA Website | Use the FAA NOTAM Search tool to find notices by airport or route. |
| Flight Apps | Apps like ForeFlight or Garmin Pilot show NOTAMs in your flight plan. |
| Flight Briefers | Call a briefer who reads and explains NOTAMs for you. |
The tricky part is that NOTAMs can be hard to read, with codes like “RWY 04L/22R CLSD”.
However, the FAA’s guide in the Aeronautical Information Manual helps decode them, and apps make them easier to understand.
Different Types of NOTAMs
Not all NOTAMs are the same.
Here’s a table of the main kinds pilots see:
| Type | What It Covers | Example |
|---|---|---|
| NOTAM (D) | Airport or navigation issues | Runway closed or broken lights. |
| FDC NOTAM | Significant changes, like no-fly zones | A TFR for a concert. |
| Military NOTAM | Military airports or airspace | Usually not for regular pilots. |
| SNOWTAM/ASHTAM | Weather or ash issues | Snow on the runway or volcanic ash in the air. |
“trigger NOTAMs” also warn about upcoming changes, like new airspace rules, lasting about 14 days.
Why NOTAMs Can Be Annoying
Let’s be real: NOTAMs aren’t always fun. They’re often written in all caps with weird codes, and there can be tons of them.
In 2017, the U.S. received about 145,000 NOTAMs a month—a lot to read!
After the 2017 San Francisco incident, the National Transportation Safety Board called NOTAMs “a bunch of garbage” because they’re hard to sort through (Wikipedia – NOTAM).
The FAA will fix this in 2025 with a new system that will make NOTAMs more straightforward and less overwhelming.
| NOTAM Problem | Why It’s Tough |
|---|---|
| Too Many Notices | 145,000 a month in 2017! |
| Hard to Read | Codes and all caps confuse pilots. |
| Old System | Crashed in 2023, causing delays. |
What’s Coming for NOTAMs?
The NOTAM system will get a significant upgrade in September 2025.
The new version will use modern tech to send alerts faster and make them easier to read.
This is a huge step up from the old system, which had issues, like an outage in March 2025 that delayed flights.
A global project, EUROCONTROL Digital NOTAM, also works on computer-friendly formats for more innovative flight tools.
| Future Change | What It Means |
|---|---|
| New FAA System (2025) | Faster, clearer NOTAMs. |
| Digital NOTAMs | Apps and tools will use NOTAMs better. |
Wrapping It Up
NOTAMs might not be the coolest part of flying, but they’re like a pilot’s safety net.
They warn about runway closures, no-fly zones, and other risks, helping planes stay safe.
Whether you’re a pilot or just love planes, knowing about NOTAMs shows how much goes into every flight.
With a significant upgrade in 2025, NOTAMs will get even better at keeping the skies safe.

Fun Fact
NOTAMs were inspired by “Notices to Mariners,” which helped sailors avoid sea dangers in the 1800s. Aviation just took the idea and made it fly! (OPS Group – FAA NOTAM Change).
