A bold and slow bushplane
Heads up! Winter is here!
When operating in cold weather, it’s better to not turn on the engine if it has not been warmed up before. The IO-520 may not even turn on when the temperature is below 3-4 °C (37-39 °F).
If you manage to make it start, you may damage it. The CHT would rise too much is a short period of time. Nevertheless, the oil would be too thick to lubricate the engine.
But…we have a solution for that!
