Known Position Reports
Definition
A known position report is a standard radio message in which a pilot reports their current location using a recognizable point, such as a visual reference, a navigation fix, or a published reporting point. These reports help air traffic services (ATC or FIS) maintain situational awareness, especially in uncontrolled airspace or when radar coverage is limited.
Purpose
- Support traffic separation and collision avoidance
- Keep ATC or Flight Information Services (FIS) updated on aircraft location
- Aid in sequencing, coordination, and entry into controlled zones
- Serve as part of standard VFR procedures at busy aerodromes or airspace boundaries
When to Make Position Reports
- When entering or leaving a control zone (CTR)
- When crossing or approaching visual reporting points (VRPs)
- When requested by ATC or FIS
- During overland navigation in Class G airspace
- In non-radar environments
- When operating on common traffic advisory frequencies (CTAF) at non-towered airports
Typical Contents of a Position Report
| Element | Example |
|---|---|
| Callsign | “OE-ABC” |
| Position | “Over reporting point Sierra” |
| Altitude | “At 2500 feet” |
| Intentions | “Inbound for landing” or “Transiting the zone northbound” |
| Time (optional) | “At 32” or “In 2 minutes” |
Phraseology Examples
Optional additions include:
- Time over fix (e.g., “At 45”)
- ETA at next fix (e.g., “Estimating Echo in 3 minutes”)
Visual Reporting Points (VRPs)
- Standard VFR entry and exit points marked on charts
- Used for CTR entries, traffic pattern integration, and coordination
- Examples: “Sierra”, “Whiskey”, “Echo”, “Delta”
- Pilots must report at or near these points as instructed by ATC
Non-Visual Known Positions
Report using VOR radials, DME distance, GPS coordinates, or airspace boundaries
Example: “5 miles east of VOR STU, FL60, estimating GITRI at 15:20”
When Required by Regulation
- As part of a compulsory reporting point
- In Class G airspace with active FIS
- When operating under Flight Plan with mandatory checkpoints
Tips for Pilots
- ✅ Use clear, standardized phrasing
- ✅ Reference chart-labeled points when possible
- ✅ Stay concise: position, altitude, intentions
- ✅ Practice with LearnATC simulator to build confidence with reporting calls
