-In a large brawl and need to look dead to avoid focus. This usually allows me to relocate.
-Mid-Air power down to avoid LRM's or fake death. Some players just can't be fooled, LRM's always can.
-While being chased find an out of view spot, power down and let the enemy walk past your location, now you have the advantage.
-If you are getting LRM'd from anywhere you've been NARC'd so power down in a safe place.
That's pretty much the limit of my power down tactics. They work more often then you would assume!
Edit; The most important one; Power Down face first into the water to maximize your K/D ratio! Don't want that dropping.
