| The paper will discuss some of the design parameters and methods used to establish good demist clearance patterns on a windscreen of a vehicle. |
| Why does my car's ventilation system demist the windscreen more quickly when I turn on the air cooling? |
| The pilot must then wait for the demist to clear the windshield before taking off. |
| The defroster functions for the front, side and rear windows can be used to demist the windows. |
| The pilot had departed Lac des Neiges with the fan blower ON but did not feel it necessary to select demist hot air for the cabin because both occupants were comfortable. |
| Therefore, as per the EC 120B flight manual4, the pilot was not restricted in the use of demist on approach and landing. |
