According to standard IFR rules (such as ICAO Annex 2 and SERA), what is the minimum vertical obstacle clearance required when flying over designated mountainous terrain?
Answer
2,000 ft (600 m)
Explanation
The chart-based terrain assessment identifies **7,926 ft** as the highest point within 5 NM either side of the track. This is a lateral-corridor terrain check, not simply the highest elevation at an endpoint. **Key takeaway:** Check terrain along and beside the planned route. **Glossary:** Lateral distance: distance measured perpendicular to the route.
