LONGITUDINAL (DME)
A/C Same Level
Same Track
20NM
provided
1) each aircraft utilizes:

b. an “on-track” DME station and a collocated waypoint when one aircraft is utilizing DME and the other is utilizing GNSS
c. the same waypoint when both aircraft are utilizing GNSS
2) separation is checked by obtaining simultaneous DME and/or GNSS readings from the aircraft at frequent intervals to ensure that the minimum will not be infringed

b. an “on-track” DME station and a collocated waypoint when one aircraft is utilizing DME and the other is utilizing GNSS
c. the same waypoint when both aircraft are utilizing GNSS
3) separation is checked by obtaining simultaneous DME and/or GNSS readings from the aircraft at frequent intervals to ensure that the minimum will not be infringed
LONGITUDINAL (DME)
A/C Same Level
