Are negative G pushovers a safe maneuver for a new private pilot to do? I had a passenger ask me to do one the other day and fought with myself about whether or not to do it. I never really went over the technique with my instructor but I have extensively researched the correct way to do it. I also know my limits and would not do it for more than a few seconds. I do fly a 172 gravity feed so the fuel is obviously a concern but I don't think a two second pushover would kill the engine. Just wanted to get your thoughts on the manuever.
