Don't know anything about SkyDemon. and don't have an I Pad. The wife has an I Pad. I will have to look into that. Do you simply keep the I Pad in your lap or do you have a yoke mount?
Yah my old Garmin 10 has never been updated in the 15 years I owned it and at least were I fly nothing has changed runway and communication frequencies have not changed. I double check with sectional and flight supplement. Don't know why the updates are so expensive, seems to me Garmin would want to keep there customer base and offer the updates at a reduced rate of free.
Thanks for the input
