I asked this on the AOPA forum but figured I would post it here as well. I am training for my IFR rating. I currently have just my private SEL. Here is the question, my plane is an RV-6, a tail dragger. I have many friends that could fly with me as a safety pilot but most do not have their tail dragger rating. When flying under the hood for practice, in VFR conditions, does the safety pilot need the tail dragger endorsement in order to act as my safety pilot. The regulations state he must be a private pilot with category and class ratings appropriate for the aircraft being flown. To me that is category, normal and class single engine land.
