I have noticed a few strange things when I fly. One is probably an illusion. Since I'm an inexperienced pilot I'm sure it takes getting used to before you can really judge. First, as the AC goes away it looks like it is getting closer to the ground. I have noticed this on flat ground. It is really weird. I put the AC up about 30 meters and as it flies away it looks like it is getting closer to the ground. I check the telemetry and note that it isn't showing that it is gaining or reducing in elevation. As I fly it closer to me it seems like it is getting higher. Does anyone understand why this is?? or is this just old man eyes. Second, I know when I fly my Phantom in ATTI mode it absolutely does shave altitude. It is something that you really have to pay attention to if you are at the edges of VLOS. To be honest I haven't flown ATTI and looked at telemetry to determine if the AC is showing a rate of descent. I just am not confident enough to do that yet. Is there something wrong with my Phantom or does everyone have a similar experience when flying ATTI.
