When a suction cup is pressed against a flight deck window, the air insde it is pusehd out, eliminating the pressure inside the suction cup and creating a vacuum which seals the cup tightly to the surface you want it to stick to. A suction cup will come off when the air pressure on the outside becomes lower than the air pressure inside the suction cup.

The care and use of suction cups:
Make sure the suction cup is clean and free from debris.
If the suction cup needs to be cleaned, wash in warm soapy water then dry gently with a lint-free cloth.
Clean the surface you are applying the suction cup to. It won’t adhere well to a dirty surface.
To enhance suction, a tiny dab of Vaseline or cooking oil may be rubbed on the rim of the cup.
Press the cup all the way down, against the surface.
The suction cup may need to be “burped” periodically by pressing down on it to remove any air that may have seeped in.
Temperature and humidity variations may make a suction cup lose its grip. If bonded above 40⁰ F/5⁰ C the cup will provide the most reliable service from -22⁰ to 120⁰ F.
To remove the cup, simply pull up on the release tab to break the suction.
