Description:

Hello everyone! S-64 is back!
This is a massive update, so massive that it is actually a new model with completely new mechanics.
And it’s the most detailed and complicated realistic mechanic I’ve ever done. And all because I managed to find the original manual for this helicopter.
So, what we have here:

– The most realistic cockpit ever.
– Simulation of systems. All vital systems have been recreated according to the original drawings and technical description. The model can be used with real documentation.
– Simulation of breakdowns and failures. The total number of possible breakdowns is approaching a hundred. For example, hydraulics alone can break down in nine different ways, and there are more than 40 electrical breakdowns. The fuel system works like a real one, and can break down in 14 ways. Engines react to weather conditions and can suffer from icing, freezing or leaking fuel, pump or injector failure, overheating or oil leakage, catch fire for a variety of reasons, or just die from overload. So is the transmission. Or as the APU. Yes, here you can burn the APU and then repair it. The rotor brake could be broken. You can even overheat the winch.

The step-by-step instructions for startup are copied from real one, with some simplifications in terms of checking systems. The video with startup procedures is included.

The minimum to watch out for in flight.
Engines:
Torque limit – 100%, exceeding 116% for no more than 15 seconds.
Oil temperature up to 121 C.
Oil pressure 45-55 PSI.
Exhaust temperature – normal up to 685, up to 720 10-minute limit.
N1 rpm nominal is up to 104%.

Transmission:
Torque limit – 82%, for a short time (10 seconds) up to 90%.
Oil temperature up to 130 C.
Oil pressure 50-65 PSI.

Fully loaded speed no more than 60 knots. Carrying capacity – 7 tons.

Under the front lower hood there is a switch for keyboard layout A / D-> right / left, and a switch for "chicken" mode, which turns off breakdowns, fires, wear, etc.

If you found any bug or strange behavior – please share so I coudl improve it!

Almost forgot. You can adjust reliability of systems in microcontrollers now!
