Window Fog
Hiya,
Seeking clarification on this.
Was driving the other day and it was quite cold outside, the windows started to fog and so I put the window blower on with hot air. Immediately the windows fogged up completely. The aircraft I fly has a defogger and I started to think hat I didn't want the same thing happening up there!!!
So, what causes windows to fog and how do you clear them?
I thought that is due to differences in OAT and cabin temp, so if it occurs then try to equalize the temps, (i.e. cold air on the window if OAT is colder, and hot air on the window on a hot and/or humid day). Is this right?
Also I'm guessing wet clothes in a warm cabin (due to evaporation) is a big no?
Thanks for your help.
