3.3 Recognise map symbols
Use these illustrated examples to identify selected operational and reference features on the Ok2Fly map.
WARNING
Map styling is supporting context, not an operational clearance or a complete aviation legend. Confirm the selected flight time, open the object details, review the complete flight-check result and check current official information before operating.
Recognise airfield envelopes
An uncontrolled airfield envelope extends three nautical miles from the airport reference point, or from the runway ends where that data is available.

Recognise runway splays
A runway splay identifies an approach and departure area relative to a runway end. Red cross-hatching identifies a no-fly area. Black cross-hatching identifies an area with a 300-foot or 91-metre height limit.

Recognise NOTAM areas
Ok2Fly can depict supported NOTAMs that define an area of activity, including UA, low-level-route and fireworks notices. An inactive NOTAM area uses a bright-yellow outline. When active for the selected flight time, it adds a red dotted fill. NOTAM timing can also affect whether restricted airspace or a danger area is shown as active.

Recognise infrastructure and activity
Purple zigzag lines follow high-voltage powerline routes. At higher zoom levels, the map can add route labels and approximate dimensions.
Android and Apple and Web
Emergency-services activity can use an icon for fire, ambulance, rescue or unknown activity. Where an affected area is available, the map can also show an outline and fill.
Android and Apple and Web
Violet dots trace a published visual-flight-rules scenic route.

Recognise an automated-authorisation grid
Eligible users can see hexagonal automated-authorisation cells in supported areas. Each cell shows the maximum altitude available for an automated request at that location.
Android and Apple and Web
The displayed value does not itself authorise an operation. See Airspace authorisations to prepare and submit an eligible request.
