Route resolved from the callsign: John F. Kennedy International Airport (KJFK) to Rome–Fiumicino Leonardo da Vinci International Airport (LIRF), confidence 20/100. A deduction from the reference data, never a measured path.

'Entry' and 'exit' mark where the station began and stopped receiving the aircraft, at the edges of the antenna's range: not where the aircraft appeared or vanished.
Start and end of contact
An altitude here falls below the ground of the covered area (lowest point: 372 m, the value drops under 300 m): suspect, probable corrupted frame.
