I just use my airplane's altimeter and let iFly pick up ADS-B soon after take-off. In the mean time, GPS altitude is fine and probably preferred near the ground.
Except that traffic altitude won't be right unless/until the iFly Altimeter is set.
Update: When I returned from my flight, the Altimeter had changed itself from Manual to Automatic.
So it appears to be doing what I would like it to do - except that Manual should stay Manual for special cases where it needs to Hold a setting.
