Q

In the strip window, what needs to be selected/ highlighted to tell OCS to apply ‘rule of 11’ between two aircraft?

A

The ‘M’ flag and the ‘R’ flag and the speed highlighted (automatically if speed is placed in the Coordination window for an active coordinate aircraft or manually selected if the clearance is given via the clearance window) for both applicable aircraft.

17
Q

Do distance based longitudinal separations require CPDLC and ADS connection?

A

Yes

18

A

No
