Climb rate after take off

not sure if anyone mentioned this but in a plane you never chase teh VSI, you climb at a given speed, and the rest will take care of itself... if you are loaded up lightly you will climb at 6,000 like in a 767 with a load.... if you are in a 152 you just go for Vy which will give you like 800 feet per minute with just you in it, and about 300-400 with two people in it...so go for the speed, never for the climb rate :)now if osmething is wrong and the plane is just not climbing like its supposed to, you might have forgteen the gear, or flaps, or something with the mixture/prop settings....you should always be aiming for Vy, and let the plane and physics do the rest :)
