Pitot tube initialization

I hear recommendations to cover the pitot tube with a hand at initialization if there’s any wind, top prevent erroneous calibration at startup.

What’s the best procedure for this? Would covering the tube with a piece of foam be more consistent than a hand?


I usually use a small plastic zip-lock bag. You can hold it with your fingers to prevent it from flapping in the wind.

Don’t use something that will close the holes hermetically, you may build up pressure by accident or burst them.
