Thats under study - and big beltway thinktank was contracted to do a mission study for CAP earlier this year. For now, its Cessna 206 and 182's. CAP is the biggest GA customer for Textron/Cessna (new 206's are $700K+). However there is serious study going on because the interagency missions keep growing (DoD, DHS, FEMA, etc.) and the SAR missions are shrinking (the vast majority of SAR cases involving downed aircraft in CONUS are resolved with crew cell phone data and ADS-B tracks). So, I've read some missions, like UAS support (think Predators in Special Use Airspace), the CAP aircraft of present are just too slow. Other missions like Private Pilot training for Cadets, a 182 or 206 is too much airplane. Given that Cirrus and Diamond are both already in AF procurement system (Cirrus for USAFA, and Diamond for AF UPT initial flight screen) it sounds like those two airframes are contenders.
The
Airvan G-8 was procured a few years ago as a trial - Think mini Caravan. I don't believe its been a successful choice. I think we have 15 of these. Box with wings.
