Not being a pilot I've never used an a/c GPS, but I do have a small hand-held unit (Garmin e-trex) and it can do elevations and multi-waypoint routes. The model I have is the most basic but I'm pretty sure that only slightly more expensive versions will also do nearest waypoint/stored location too. Dunno if this helps...
