PART 7
INSTRUMENTS AND EQUIPMENT

INTRODUCTION TO PART 7

Part 7 of the Regulations presents regulatory requirements for instruments and equipment on aircraft expected to operate in Saint Lucia. The requirements in Part 7 address 3 categories of aircraft operations. The sections of Part 7 applicable to all aircraft address minimum requirements, and are noted by the key [AAC] preceding the particular section. It is important to note that the AAC designation applies to all aircraft in the Commercial Air Transport [CAT] and AOC Holder [AOC] categories unless other, more specific regulations supplant the [AAC] requirement. In some instances, certain items such as Mach meters or sea anchors apply only to aircraft with performance characteristics requiring such items. Some [AAC] requirements apply to passenger-carrying aircraft. In such instances, the requirement addresses the operation of any passenger-carrying aircraft, most particularly corporate aircraft, that may have performance and range capabilities matching the type of aircraft operated by commercial air transport entities or AOC holders. Similarly, some equipment specified for [CAT] or [AOC] aircraft have sections keyed as [AAC]. In such instances, if a non- [CAT] or [AOC] aircraft is fitted with such equipment, the equipment characteristics must comply with the applicable sections designated [AAC]. The key [CAT] addresses those aircraft operated commercially, that is, for compensation or hire, within Saint Lucia or into or from Saint Lucia. [CAT] requirements will apply to [AOC] aircraft unless a section designated as [AOC] supplies a more specific requirement. The key [AOC] applies to AOC holders operating in Saint Lucia, whether on domestic or international flights. Certain sections, such as those addressing MNPS airspace, may not address airspace contiguous to Saint Lucia, but anticipate that Saint Lucia AOC holder's aircraft may operate through such airspace in the course of commerce. Such requirements are intended to facilitate the integration of Saint Lucia AOC holders into such operations. As in other Parts of these Regulations, operators of aircraft operated in Saint Lucia but registered in another Contracting State must notify the Authority in Saint Lucia when alterations, major repairs or major alterations are made to the aircraft. Saint Lucia may have unique territorial or geographic features that may affect the operation of aircraft, and must be kept informed of the condition of aircraft operated within its borders.
