How many planes in an army Build?

How many planes can be in an army Build?  I had two people saying you can only have 2 planes in an army build. If so where does it state this?  I have been looking and have not been able to locate the rule or restrictions.

(Before anyone says for Drukhari that it is not good idea for are armies to have more then 2 planes I agree.  I just want to know if this restriction is or I have been told bad information.)

there were some new updated rules last week (we received some point nerfs, might be interesting for you)

Now any armies can only include 2 Aircraft for Strike force and only 1 in Incursion or COmbat PAtrol, only in Onslaught games can you include 3 Aircraft

Yup, @Kalmah speaks truth.

Keep in mind that this is 2 aircraft per ARMY, not per Detachment.

However, the standard dark eldar aircraft build is centered around 2 Voidraven Bombers in a Poison Tongue patrol. So our build isnt really affected by this change. In fact, our VRB went down 10 points, so we may actually be MORE viable post-NERF with aircraft.

AoW just put out a new tier-ranking yesterday, and Dark Eldar are placed in the #2 spot, right behind Grey Knights. Just sayin

Can you let me know which book or where this rule is located. I have appreciated the help gentlemen.

It's in the Balance Dataslate released last week on Warhammer Community:

It hasn't been published in any core rule books, yet. The only reference is the balance update GW released on their community site.
