Altitude Angel, a leading provider of UTM (Unified Traffic Management) technology worldwide, has introduced two substantial updates to its map data to enhance the comprehension of airspace constraints and NOTAMs (Notice to Air Missions) for drone operators and recreational users.

As part of Altitude Angel’s ongoing efforts to refine its airspace data processing, it has extended its coverage to include the Remarks section for all ‘Danger, Prohibited, and Restricted Areas.’ These Remarks are sourced from the relevant governing authorities and typically furnish additional in-depth information to other airspace users. This added information encompasses details on timing, the nature of potential hazards, the type of restriction imposed, and contact information for the responsible authority.

For instance, Salisbury Plain is now displayed as follows:

The second update involves expanding the coverage of specific NOTAM categories. Altitude Angel has a continuous process for reviewing the NOTAMs it disseminates via its platform. This review aims to determine the relevance of NOTAMs to Unmanned Aircraft Systems (UAS) operations, with the intention of excluding those that are unrelated, such as NOTAMs pertaining to ATM infrastructure (e.g., radar systems) and aerodrome services (e.g., firefighting), among others.

In the most recent update to the map data, Altitude Angel has enhanced the range of NOTAMs accessible on the Drone Assist app and Additionally, these expanded NOTAM categories are now available to Altitude Angel’s CLOUD customers who utilize the company’s airspace data service.

The newly included NOTAM categories encompass:

  1. GNSS area-wide operations (pertaining to jamming trials).
  2. Obstacles (associated with cranes or rigs).
  3. Captive balloon and Kite NOTAMs.

Simon Wynn-Mackenzie, Vice President of Product at Altitude Angel, expressed, “We are constantly dedicated to enhancing and updating our datasets, as well as refining the information that should be presented. Our objective is to provide users and customers with the highest-quality service, enabling them to make well-informed decisions regarding their flight operations through access to precise, dependable, and up-to-the-minute information.”

Wynn-Mackenzie emphasized that Altitude Angel’s decision to introduce these additional NOTAM categories was driven by feedback from operators who sought a deeper understanding of restricted areas and a broader range of NOTAM categories that could potentially affect the safety of their flights. He hopes that these enhancements will be well-received by Altitude Angel’s user community.
