Introduction

Airspace can be complicated. Many rules and regulations exist to govern UAS operations in the United States and around the world. Furthermore, which of these regulations apply to a pilot in command, and what steps they need to take for compliance, can differ based on a number of mission characteristics. While location is the most important, factors such as a pilot's licensing, whether they are being financially compensated, and characteristics of their UAS can alter which rules must be followed. Providing a pilot with only the information that is relevant to this context around a given flight is the core of AirMap's Contextual Airspace model.

Utilizing Contextual Airspace, your application can provide a pilot with an intelligent way to understand the airspace around them in the Discover phase of flight. With a bit of additional input upfront, the pilot receives only the relevant information to assist them in planning a safe and compliant flight. This input comes in two short steps:

  1. The pilot determines what rules they will fly under, selecting from Rulesets provided by the AirMap Rules API in response to a location query
  2. Based on the requirements of the rules selected, the pilot is prompted for Fight Features such as their credentials, equipment, and environment which are evaluated by the AirMap Flight API to determine compliance

Rulesets

The core characteristic of AirMap's Contextual Airspace is the concept of rulesets, or sets of rules that a pilot is operating under. Rulesets may be one of three types:

  • Required: Rulesets that apply to most pilots and cannot be disabled, such as Restricted Airspace
  • Optional: Rulesets that are not mandatory, but include recommended advisories such as schools. The pilot may disable them as desired
  • Pick One: Rulesets where the pilot must select one item from a list. For example, pilots operating within the US must select between Fly for Fun (Part 336/101E), FAA Section 333 Exemption Holder, or FAA Part 107 Certified

Example

You can find an excellent visual implementation of Rulesets in the AirMap Web App. Consider that, when flying near airports in the United States, recreational (Fly for Fun Part 336/101E) pilots must abide by rules for flying within five miles of the airport, whereas commercial (FAA Part 107 Certified) operators are only concerned with any controlled airspace in the area, regardless of distance from an airport. In addition, all pilots must abide by required rules around Special Use Airspace and National Parks.

In the AirMap application, we can navigate to an area near Los Angeles and select the "Fly for Fun" ruleset from the Pick One list under the "What's Your Mission?" menu. The resulting view includes only the airspace around airports (orange five-mile rings) relevant to the recreational pilot, in addition to restricted zones, in red, required for all pilots:

In contrast, selecting the "FAA Part 107 Certified" option as a commercial operator removes the orange five-mile rings around airports and replaces them with the boundaries of controlled airspace in the area in blue and magenta:

Best Practice

In order to utilize Contextual Airspace in your application:

  1. Use the Rules API to identify available rulesets in an area
  2. Inform the pilot of any Required rulesets
  3. Provide the pilot the ability to select from any Optional or Pick One rulesets

Flight Features

Flight Features extend the concept of Contextual Airspace further by evaluating a pilot's flight details against the rulesets they have selected. Head over to Flight Features for a more detailed explanation.
