What is your recommendation concerning radar usage? I mean tilt; do you have kind of "standard setting" when using GMAP mode?
SAR Radar/FLIR approaches normally start from an MSA of 1500'. Initially down to 200' using the AP Transition Down function. During the RFA the Pilot Monitoring is adjusting the radar to give the best possible returns and giving a verbal picture and headings to the pilot flying. The FLIR operator is observing the track ahead and confirming these headings are clear. Once at 200' and inbound to the final approach point the search radar is fine-tuned. Final approach checks are now carried out before engaging the Transition Down to Hover function that will automatically descend the aircraft to the minimum height set.
Unlike an offshore O&G type of ARA, there is no defined Mapt as the aircraft is now at the minimum height (say 50') with a groundspeed at whatever the operator sets (normally 10 kts or vessel speed plus 10 knots). A missed approach procedure will have been pre-briefed in the event that there is no visual contact at minimum range. This involves changing the heading to a safe one using the AP and engaging the Tansition Up function that sets a pre-determined height and speed. The climb-out flight path is cleared using the search radar, FLIR and/or NVG.
