121.5 MHz SAR without SARSAT Minnesota Wing Air Branch Director Course
Overview • Information you will get • Possible approaches • Results so far • Other things to consider
Information you will get • Mission Number • Airborne reports • Airborne report search areas are huge compared to SARSAT data. • From 3,000’, a radius of 68 NM is possible. • From 30,000’, that radius could be 200 NM. • SARSAT average accuracy: 10-15 NM. • AFRCC may have contacted several airports to check for signals on the ramp and may provide that info.
Possible Approaches • Get an aircraft up if at all possible! • Aircraft can cover a lot more ground in attempting to troll for signal. • Even IFR sorties at high altitude can help narrow down the signal. • They just need to get the ground team close enough to pick up a signal.
Possible Approaches • If you have a large area, launch multiple aircraft • Ensure you have some sort of separation protocol in place.
Possible Approaches • If you can not launch an aircraft, deploy several ground teams to start doing ramp checks and “trolling for signal”. • This type of search will be extremely difficult. • Continue to ask for more airborne reports at as low of an altitude as possible to hopefully help narrow down the area.
Results so far: • Two searches from airborne reports since 1 Feb 2009: • First was “6 Airborne reports with lowest being 9 miles north of Faribault at 6000 ft” • Weather was a possible issue. • Ground teams from Mankato, Red Wing, 130th were preparing to do ramp checks. • Did break enough for an aircrew out Lakeville to launch and pick up the signal near Owatonna Airport. • MKT ground team diverted there and signal was silenced. • Total Flight Time: 1.5
Results so far: • Two searches from airborne reports since 1 Feb 2009: • Second was “11 airborne reports of an ELT 10 mi NE of St Cloud” • Ended up being at Leaders Field • MIC aircrew heard it when they flew over en route to St Cloud. • Directed STC ground team into the site. • Total flight time: 1.7 hours
Other Considerations • Searches will take longer. Will probably need to get more personnel involved to handle the larger search areas. • May need more mission staff if the mission goes into multiple operational periods. • Training needs to be modified • Airborne reports and much less accurate data to start the search.
