If a plane without any deicing equipment has water moisture on the wings (say, from sitting overnight) and that plane is then flown to an altitude which will have temperatures below freezing, what is the risk of that initial moisture causing icing concerns?
For the sake of hard examples:
- Plane: Piper Cherokee 140
- Air temperature on ground: 40°F (4°C)
- Air temperature at cruise altitude (3500ft): 28°F (-2°C)
- No visible moisture in the air, the only moisture is the moisture on the wings prior to takeoff.
- Will this be a problem?
- If it is a problem, what is the best course of action to protect against the icing concern?
