How to file a notam - Quick, Step-by-Step Guide

Decoding NOTAMs: The Backbone of Aviation Safety

Understanding how to file a NOTAM starts with understanding its core purpose: aviation safety. A Notice to Air Missions (NOTAM) acts as a vital safety alert, providing pilots with crucial information about potential hazards along their planned flight path.

These hazards can vary widely. They might include runway closures, ongoing construction projects, adjustments to airspace restrictions, or even unusual bird activity. Armed with this information, pilots can make well-informed decisions, modify flight plans as needed, and ultimately, ensure safe flight operations.

The Evolution of NOTAMs: From Teletype to Today

NOTAMs began as basic teletype messages, a world away from today’s more complex system. Despite the technological advancements, the core purpose of a NOTAM has remained constant: delivering timely hazard information. Whether received through traditional methods or via modern digital platforms, the critical function of a NOTAM remains unchanged. You can learn more on this blog. The system is a constant, unseen safety net, continually monitoring and communicating potential issues to maintain the seamless flow of air traffic.

Understanding the Different Types of NOTAMs

NOTAMs are not a uniform communication. Different types of NOTAMs exist, each with a specific purpose. Some NOTAMs address transient situations, such as equipment malfunctions or temporary construction. Other NOTAMs communicate longer-term airspace alterations. Additionally, NOTAMs are classified by their distribution and level of urgency. A clear understanding of these differences is essential for the proper creation and interpretation of NOTAMs. This is especially true when learning how to file a NOTAM.

The Growing Volume of NOTAMs: A Challenge for Pilots

The increasing volume of NOTAMs presents a growing challenge for pilots. In 2020 alone, over 1.7 million NOTAMs were issued worldwide, marking a consistent yearly increase of more than 100,000. Even with a brief dip in 2020 due to the COVID-19 pandemic, the volume of NOTAMs remains substantial. For a long-haul international flight, a pre-flight briefing package can easily exceed 100 pages, with an estimated 20% containing outdated information. This high volume, coupled with the presence of irrelevant data, highlights the ongoing need for NOTAM system improvements. ICAO’s NOTAM2021 campaign is one such initiative. It aims to reduce unnecessary NOTAMs and ensure the efficient delivery of only vital and timely information. You might also find this helpful: How to master airspace user contact information.

When to Pull the Trigger: Identifying NOTAM-Worthy Situations

Knowing how to file a NOTAM is essential, but knowing when to file is just as critical. Not every airport hiccup requires a formal NOTAM. This section helps clarify which situations demand a NOTAM and which are best handled through other means of communication.

Understanding The Threshold For NOTAMs

The main factor in deciding whether a NOTAM is necessary is the potential impact on flight safety. A small issue, like a temporarily closed restroom, wouldn't need a NOTAM.

However, a runway closure, regardless of how brief, absolutely does. This ensures pilots know about the change and can alter their flight plans.

Construction Impacts And Equipment Outages

Construction work affecting navigable airspace, such as crane operations or temporary structures, generally requires a NOTAM. Likewise, outages of essential navigation tools, like Instrument Landing Systems (ILS) or airport lighting, need immediate NOTAM filings.

This prompt communication allows pilots to plan alternate landings or divert to other airports if needed.

Temporary Restrictions And Other Considerations

Temporary Flight Restrictions (TFRs) imposed for special events, security concerns, or natural disasters always demand a NOTAM. Unexpected hazards, such as substantial bird activity or the presence of Unmanned Aircraft Systems (UAS) near the airport, often warrant a NOTAM as well.

These conditions can be a direct danger to aircraft and require swift communication.

To help illustrate the difference between situations requiring a NOTAM and those better suited for alternative communication, let's examine a comparison:

This table provides clear guidance on which situations require a NOTAM filing versus those that can be handled through other communication channels.

Condition Type	NOTAM Required?	Alternative Communication	Time Sensitivity
Runway Closure	Yes	None	Immediate
Restroom Closure	No	Airport signage, internal communication	Low
ILS Outage	Yes	None	Immediate
Construction impacting airspace	Yes	Pre-planned NOTAM for expected durations	As scheduled, immediate for unexpected changes
Bird activity	Yes, if significant	Internal communication if minor	Moderate to High
UAS near airport	Yes, if posing a threat	Local UAS operator advisories if manageable	Moderate to High
TFR	Yes	None	Immediate

As you can see, the need for a NOTAM is driven by the potential for a condition to impact flight safety. Less urgent issues can be effectively addressed through channels other than NOTAMs.

Examples Of NOTAM-Worthy Situations

• Runway closures: Full or partial closures always require a NOTAM.
• Navigational aid outages: Problems with systems like ILS or VOR require immediate notification.
• Construction near the airport: Projects affecting defined airspace warrant a NOTAM.
• Obstructions: Unexpected obstacles, such as cranes or damaged buildings, need a NOTAM if encroaching on airport airspace.
• Military exercises: Training involving airspace restrictions or unusual aircraft movements requires NOTAMs.

Understanding these examples and the possible hazards they create helps determine when a NOTAM is necessary. By carefully considering flight safety impacts, you can use NOTAMs effectively to improve aviation safety and avoid information overload. This ensures pilots receive crucial information for safe and efficient operations. Effective NOTAM management is a shared responsibility, improving the overall safety and efficiency of the National Airspace System.
