I'll try to get more 212 pictures on the page, all of the pictures are taken in a 25 NM radius of Mexico City, Mexico, the elevation here is 7,340 FTMSL, and density altitude is usually above 9 or 10,000 feet.

Most of the heliports in the pictures are above 8,000 FTMSL, and the interesting part is that many times you have to land or takeoff from these heliports with only enough power hover IGE, and not enough to hover OGE, this means the approach has to be very accurate if you don't want to start to settle before you reach your spot close to 100 power, also you have to leave the pad with enough forward speed so that when the heli goes OGE and settles the tail won't hit the bldg., it is not uncommon to see these helicopter agressively diving for the ground (to gain speed and clear the tail) right after takeoff from one of these tall buildings.

In the last years the helicopter performance has improved the 412 has become 412EP, the AS365 is now 365N3, the 230 is now the 430, and and we don't sweat it soo ofter now, but before in lesser performance helicopters you had to develop a real feel for the helicopter, power was always at the limit and you had to sweat your way out.
