bold font: FOR USE BY CASA-APPROVED OPERATORS ONLY.

 The use of the specialised helicopter procedures is limited to CASA‑approved operators only.

       Note   The CASA Area Office forwards to the Manager, CNS/ATM, copies of the relevant parts of each prospective operator's operations manual. The Manager provides operators with an approval for each TIFP, in accordance with Part 173 of CASR 1998 and this MOS. CNS/ATM also maintains a register of operators authorised to use the procedures, and holds the relevant part of the operators' operations manuals.

8.8.3                   Procedure Overview

8.8.3.1              All helicopter procedures designed under this section are to be designed in consultation with the local operator. Helicopter procedures are dependent upon visual segment procedures developed by the operator in consultation with the procedure designer. Operational procedures must include key visual features, hazards, routes to be flown and action to be taken in the event that meteorological conditions deteriorate below specified requirements and any other conditions relating to the procedure.

8.8.3.2              The operating procedures are to be included in the Operations Manual of an operator approved to use the procedure.

8.8.4                   Visual Approach Area—Helicopter

8.8.4.1              Helicopter procedures will normally be designed with a Visual Approach Area - Helicopter (VAA-H).

8.8.4.2              Procedures that do not provide a VAA-H are to be noted accordingly on the approach chart.

8.8.4.3              The VAA-H criteria are based on the establishment of key visual lead-in features to the HLS. In this respect, each procedure will be unique and requires an operational specification to be included in an operator's operations manual.

8.8.4.4              The procedure designer must liaise with operators to define key lead-in features.

8.8.4.5              During validation, particular attention has to be considered for local operating procedures and key lead-in features.

8.8.4.6              This area is located between the MAPT and the HLS within which obstacle clearance at MDA is assured.

8.8.4.7              Operations within a VAA-H are visual flight manoeuvres. Once visual contact is established during the instrument approach, the helicopter is positioned within the VAA-H and manoeuvred utilising key lead-in points at altitudes not below the MDA until the HLS is sighted. (See AIP).

8.8.4.8              The missed approach criteria detailed in PANS-OPS are modified to take account of the VAA-H.

8.8.4.9              The centre of the HLS must be surveyed to an accuracy of 1/100th of a second of arc.

8.8.5                   VAA-H Dimensions

8.8.5.1              Area. The VAA-H starts at the commencement of the missed approach segment with a width equal to the width of the final segment primary area at that point. Its boundaries join at a tangent to a circle of 926 m radius centred on the HLS (see Figure 8-28).

8.8.5.2              Length. The nominal length of the VAA-H is 3
