In Grand Theft Auto 5 (GTA V) on the PC, PS3, and Xbox 360, you can find a Buzzard (the attack helicopter) without using any cheats to spawn one.
On the east side of the city near the starting area (toward the Palomino Highlands area), you’ll see a highway that leads northeast of the city and curves toward the north the further out it goes.
If you take the first right on this highway, and then go left when the road splits. Go to the very end of this road heading north and you’ll end up at the Los Santos Government Facility.
Once you go through the first gate, take an immediate left and bust through the chain-link gate. No one will come after you for doing this.
Straight ahead will be a tall building with several ladders going up. Climb up to the top and you’ll find the pretty little Buzzard Attack Helicopter waiting for you to steal.
