Does AMC1 CAT.POL.H.215(a)(1);(a)(2) specify a different lateral distance for PBN operations compared to non-PBN operations?

Yes, for PBN operations the distance should be equal to or greater than the required navigation performance, whereas for non-PBN operations the default is 9.3 km (5 NM) increased to 18.5 km (10 NM) if navigational accuracy is insufficient.

AMC1 CAT.POL.H.215(a)(1)

Q: What lateral distance on either side of the intended track should be considered for terrain and obstacles when assessing en-route critical engine inoperative performance under AMC1 CAT.POL.H.215(a)(1);(a)(2)?

9.3 km (5 NM), which should be increased to 18.5 km (10 NM) if the navigational accuracy cannot be met for 95% of the total flight time.

Q: Under what condition must the lateral distance for terrain and obstacle consideration be increased from 9.3 km to 18.5 km?

If the navigational accuracy cannot be met for 95% of the total flight time.

Q: When flying in accordance with PBN procedures, what lateral distance should be used for terrain and obstacle consideration in the en-route critical engine inoperative assessment?

A distance equal to or greater than the required navigation performance.
