Wind Pattern
The wind rose diagram for Coimbatore shows the frequency per month for expected wind speeds. It also shows for how many hours per year the wind blows from the direction, which is SW: Wind is blowing from South-West (SW) to North East (NE). Thus preferred approach path for Ganga Hospital Helipad should be SW to NE .Refer Appendix-H (Wind Rose Diagram)
There is clear approach path available along the direction 08/26, which meets the requirement of normal wind direction prevailing in the region. It is envisaged that this direction would cater to operations around the year and the pilots are to use this direction only. However, it may occur on a few occasions that due to local weather phenomenon in the area, the wind may back or veer. Under such circumstances, the pilot may use his discretion to take off and approach in a direction 30 degrees on either side of 08/26.

The helipad is located in close vicinity of Coimbatore airport, co-ordination with the ATC shall be done before departure/ arrival at the Ganga helipad. Coordination with Sulur shall be established in the absence of the coordination with Coimbatore ATC/ or if required.
The crew/Ops Department (Delhi) is to obtain the current weather from Coimbatore ATC/ Met Section and pass it to the crew.
The area of operations, being close to the Nilgiri ranges, is known for constantly changing and gusty winds as well as unpredictable weather deteriorations. There have been accidents/incidents in the past due to dynamic rollover and other weather related incidents in this operational area. Crew are to take cognisance of the fact that very high wind speeds of over 40 knots can be encountered in this area, therefore, all take offs and landings are to be carried out with extreme caution.
The take-off and approach directions at Coimbatore and Sulur airports being 05/23, any operations towards South of the helipad are likely to be affected by traffic arriving/ departing at these airports. Therefore, after departure from the helipad, positive contact needs to be established with Coimbatore ATC before turning towards Southerly direction. This may be coordinated before departure.
After obtaining the ADC/FIC/Level Clearance/Squawk from Chennai FIC/MLU, the crew are to contact ATC Coimbatore on landline to get the traffic update and the instructions to be followed after departure from the helipad. Any undue delay in departure due to any unforeseen circumstances needs to be intimated to ATC Coimbatore.
It is likely that patients or passengers with special medical conditions are transported in the helicopter. The PIC is to make all effort to get to know the medical condition of the patient and any special precautions/care that may need to be taken. All efforts are to be taken to maintain a maximum rate of climb/ rate of descent of 500 feet per minute and bank restricted to 15 degrees.
