Question

On Jeppesen area and enroute charts in areas officially designated as 'mountainous,' the MEA or MOCA of airways will guarantee how many feet obstruction clearance?

1) A minimum of 1,000 feet.
2) A minimum of 2,000 feet.
3) A minimum of 1,500 feet.
4) It depends on the highest terrain feature in the area.

Answer 1

In mountainous areas on Jeppesen charts, the MEA or MOCA ensures a minimum of 2,000 feet of obstruction clearance for aircraft safety.

Step-by-step explanation:

On Jeppesen area and enroute charts in areas officially designated as 'mountainous,' the Minimum Enroute Altitude (MEA) or Minimum Obstacle Clearance Altitude (MOCA) of airways will guarantee a minimum of 2,000 feet obstruction clearance. This clearance is essential for the safety of aircraft navigating through mountainous terrain, where the elevation changes can be significant and abrupt. The regulations ensure that there is enough vertical space for an aircraft to avoid terrain and man-made obstacles.

On Jeppesen area and enroute charts in officially designated 'mountainous' areas, the MEA (Minimum En Route Altitude) or MOCA (Minimum Obstruction Clearance Altitude) of airways guarantees a minimum of 2,000 feet obstruction clearance. This ensures that aircraft flying in these areas have sufficient vertical separation from the highest terrain feature.
