Periodically I compare my terrain warning altitudes/colors against reality. I don't use it for nav, but it's comforting to know that it's there, since I fly in the mountains a lot. Terrain warning altitudes have been fairly accurate for years, but last weekend it was dangerously far off, and I...

Chair flying, cuz the weather sucks... What happens if the AP is in active mode "GPS+ALT", nothing is armed, and I upload a new flight plan from ForeFlight?

Sudden loss of torque on a servo that has seen light use over 300 airframe hours. I was straight and level in smooth air. Then the "heavy" wing began to droop, and the HDX showed "roll slip". I could feel on the stick there was no servo torque at all. If I disengage and re-engage there's a...

I have the latest data from Dynon and Seattle Avionics loaded into my HDX. I encountered an airport traffic pattern (TPA and direction) where the HDX is giving incorrect information. It seems the suggested pattern, direction, altitude are all applicable to helicopters only. I've never seen...

The title pretty much says it all. I have not had good luck at all with the normal AOA calibration procedure. I keep all my logs, and upload them to SavvyAviation. By examining those logs at the point in time where I was practicing stalls, can I extract reasonable values for the purpose of...
