LATERAL OFFSETS AND THE RETURN TO THE ORIGINAL ROUTE
The OFFSET function creates a path parallel to the active route at a selected side and distance. It is not a heading instruction and not a new airway. Fenix V3 explicitly addresses offset behaviour. The detailed access conditions and limits described here come from the supplied Thales standard; inspect the actual installed page before assuming every option or edge condition is identical.

1. Establish the intended offset and extent. Confirm the cleared side, distance and where the offset should end. Open LAT REV at the appropriate FROM/present-position context and select OFFSET when available. The source excludes particular approach, gradient and large-turn situations. A missing prompt can therefore reflect leg applicability rather than a failed key. Read the current leg before trying an offset from another page. [66, PDF pp. 373-377,670]
2. Enter direction with distance. The source uses forms such as 5L or L5 for five nautical miles left. This is a format example, not a default offset for our route. Read the accepted side and magnitude. Inspect the temporary entry turn, parallel section and return/end point on the ND; a correct distance on the wrong side is an incorrect path.

3. Insert and verify the path. Confirm the active offset indication and actual lateral guidance. The source preserves a depiction of the original track separately from the offset track. Establish which is being flown. Review turn geometry and relevant restrictions along the affected segment; do not use the visual similarity of the parallel line to assume that all procedure applicability and obstacle considerations have been resolved.

4. Cancel through a reviewed return. The guide describes entering zero or CLR in the offset field, then reviewing and inserting the computed return path. Removing the number is not permission for an unexamined turn back to the original line. Read the resulting TMPY and coordinate the return with the clearance before commitment. Afterwards inspect the actual active leg and mode. [66, PDF pp. 373-377,670]
5. Review automatic removal. The source describes offset deletion after changes that invalidate its geometry and on certain plan activations. Read OFST-related messages and inspect the new path rather than assuming the parallel track persists. A secondary-plan activation or late route change can therefore require a fresh offset decision. The completion point is an understood active track and extent, including how the aircraft will return to the original route. [66, PDF pp. 373-377,670]
