Intentionally Blank
Notes:
1) The minimum operating height refers to the height Above Ground Level (AGL) for overland flights, and the height Above Mean Sea Level (AMSL) for offshore flights.
2) VFR Flights may not depart or continue if the weather conditions at departure, en-route or the destination are below the above stated minimum.
3) Minimum operating height for Day VFR less than a ceiling to 600 feet (inclusion of 100 feet of cloud clearance) and visibility to 2 SM may be allowed if the procedures are authorized by the appropriate authority.
4) When lower minimums are used, it is recommended that only those twin-engine IFR certified with a dual pilot IFR current crew be used.

Appendix 7
Recommended aircraft equipment fit
Equipment requirements for aircraft are an important consideration and can have an impact on the aviation portion of a project’s budgets. Consequently it cannot be overstated that the Aviation Advisor must be involved as early as possible, and have a clear understanding of the project and the associated constraints. Ultimately, the goal is to correctly equip the aircraft to match the task thereby enabling the crew to complete the job safely.
In determining appropriate aircraft and equipment several points need to be considered; project needs, the environment to be operated in, and the length of the contract.
Project needs should be clearly understood by the aviation advisor.
1) Is the aircraft to fly cargo and or passengers?
2) Will the operation include offshore operations or other specialized operations?
3) Will the aircraft be used to provide medical evacuation support?
4) How critical is aviation support to the overall project?
The operating environment for the project refers to the distinction between Hostile vs Non-Hostile environment. Hostile is an environment where a successful emergency landing cannot be assured, the occupants of the aircraft cannot be adequately protected, or search and rescue response/capabil-ity cannot be provided consistent with the anticipated exposure.
