Garmin 100 GPS IFR Legal?
IFR turbo-prop charter equipped with Garmin 100 GPS. Is it legal to plan IFR STARS and SIDS, direct routing etc based upon this type of GPS? Or should flights be flown on ERC and TAC routing using conventional navaids with Garmin 100 used as a back up only. Are Garmin 100 GPS sets VFR only?
