3.1.11 Recommendation.- Where parallel instrument runways are intended for simultaneous use subject to conditions specified in the PANS-RAC (Doc 4444) and the PANS-OPS (Doc 816

, Volume I, the minimum distance between their centre lines should be:
- 1035 m for independent parallel approaches;
- 915 m for dependent parallel approaches;
- 760 m for independent parallel departures;
- 760 m for segregated parallel operations;
except that:
a) for segregated parallel operations the specified minimum distance:
1) may be decreased by 30 m for each 150 m that the arrival runway is staggered toward the arriving aircraft, to a minimum of 300 m; and
2) should be increased by 30 m for each 150 m that the arrival runway is staggered away from the arriving aircraft;
b) for independent parallel approaches, combinations of minimum distances and associated conditions other than those specified in the PANS-RAC (Doc 4444) may be applied when it is determined that such combinations would not adversely affect the safety of aircraft operations.
