f-16 fog

[CraigCantwell]

Under the right conditions, the ECS system in an F-16 can turn the cockpit into zero visability in seconds. Defog can take as little as 15 seconds to clear and as much as 30 seconds. Any ECS control other than the defog lever requires the pilot to remove his hand from the stick.....not exactly what you want to do at 100' and 125+ kts on final or above nosewheel steering limits on the runway.

I've been in the back seat on ground runs that went to zero vis in the cockpit in less than 30 seconds. It was bad enough that I couldn't see my engine guy in the front seat other than a dark shape. I've even had it rain on me due to ambient conditions and a really cranky ECS.
