Question

Aircraft during IFR operations within a mountainous region, shall be flown at an altitude of at least ____ feet above the highest obstacle within 5NM of the aircraft in flight when in areas 1 and 5, and at least ____ feet above the highest obstacle within 5NM when in areas 2, 3 and 4. (FIGURE 2.10 IN RAC)

Answer 1

For IFR operations in mountainous regions, the altitude should be at least 2,000 feet above the highest obstacle within 5NM in areas 1 and 5, and at least 1,000 feet above in areas 2, 3, and 4.

Step-by-step explanation:

The altitude requirements for IFR operations within a mountainous region, as given by aviation regulations, are dependent on the area in question. For areas 1 and 5, the aircraft must maintain an altitude that is at least 2,000 feet above the highest obstacle within a radius of 5 nautical miles (NM). When operating in areas 2, 3, and 4, the minimum clearance increases to 1,000 feet above the highest obstacle within 5 NM.
