What is the difference between the A320-212 series and the A320-214 series?

Is there any significant performance or design features??

Numbers depend on the engines that fit the aircraft. 1x when it is G/S CFM and 3x when it is IAE.

This isn't exactly on topic but it relates to the A320.
I can remember seeing (in the thread about the jetblue A320 emergency) that the A320 does not have a dump valve so it can't dump fuel, it has to circle to burn the fuel until it's reached it's MLW. Isn't this a bit of a design flaw? What if a person has a heart attack and needs to get medical treatment as soon as possible? The A/C will have to circle (depending on the amount of fuel) a long time.

By the time the MLW has been reached the person could already be dead.

What are your views on this?

It`s an interesting question. Here another one:
Are there other planes which have no dump valves?

It was circling to expend fuel to reduce the weight, yes, but not to reach MLW. There's practically no difference between the A320's MTOW and MLW for all intents and purposes.

The B6 A320 had a catastrophic gear failure. You want to reduce your weight as much as possible, for obvious reasons including stopping distance doing a soft field landing.

Easy. You do an overweight landing. Every plane in existence has to be able to land, at least once or twice, at its MTOW.

CRJ, ERJ, E-Jets, DC9, MD80, MD90, 737, 757, 99% of 767s, and 99% of A330s

Thanks, that makes sense.
What effect does an overweight landing have on an A/Cs landing gear?

wow never knew so many A/C didn't have dump valves.
Any particular reason why they don't have dump valves?

Thanks

Generally speaking, I believe that the landing gear is built to withstand such a shock. It is the remainder of the impact that is not absorbed by the landing gear and then transferred to the airframe that matters.

In extreme cases, rivets are popped, deformation of fuselage skin panels result and even cracking of structural components. I've seen where an aircraft simply is taken in for a thorough inspection following an overweight landing and came out alright.
