I was thinking about this today... and even did a quick google search to see if anyone had thought of this already, but came up with nothing. So, your an IFR pilot, and you need to do your 6 approaches, holds, etc. within 6 months in actual, sim, trainer, etc. - and you have to have a safety pilot or CFI, etc. With today's technology... What if Pilot A owned his / her own SIM at home, and Pilot B acted as a safety pilot but wasn't physically at your house when you wanted to do some procedural work? (Say You're in Denver, and they're in Washington). Why couldn't you hook up a webcam, or have them remote desktop into the machine / webex or something to satisfy the requirement, and then just have them sign / fax a logbook entry? Wouldn't that all still technically satisfy the rule? Just curious if anyone has even thought of this.... I mean I suppose you could make a business out of this too... "rent a remote safety pilot"
