1. Possibly, but iPhone's screen is pathetic in sunlight, and it's speaker is probably not loud enough for variometer beeping. Also, not sure if it has enough battery power for 4 hours of such workload. 2. AoA is too low-level for me personally. I'd rather see my airspeed and glide ratio relative to the air. Hang gliders stabilize themselves at an optimal AoA if you stop providing inputs, but sometimes when I'm desperately trying to reach the landing field I want to know if I should increase or decrease the speed to get there (tradeoff between headwind penetration and sink rate). Also, personally I'm not going to install anything requiring long wires. There's just too much hassle already in setting up a hang glider... I just want to put the whole device with any sensors in clean airflow and forget about it. Oh, one more thing I would like is a G-force meter. I'm not supposed to exceed 4G positive on my glider, but I have no idea how it feels like. I'm not going to reach it with normal flying but once I start doing wingovers and loops, I would like to know the numbers I'm getting.
