[ACADEMIA] Helicopter performance calculations tutorial?


Recommended Posts

Posted

Hi, are there Huey specific calculations parameters chart or tutorial that I can use to predict and adjust performance as needed? I am fairly new to even trying performance calculation, perhaps one of you slick pilots could help me by directing me to the right direction (reading). I'll be updating this thread with learnt knowledge in hopes to be a reference for newcomers.

 

 

So by just looking at a chart for helo ops - a performance chart , what is hover torque OGE, hover torque IGE. I know there is a chart for required hover (XX feet skid height) versus GW versus temperature, but what other charts to look at during performance planning.

 

I feel this will make it more predictable, short of feeling the real thing of course.

Fat T is above, thin T is below. Long T is faster, Short T is slower. Open triangle is AWACS, closed triangle is your own sensors. Double dash is friendly, Single dash is enemy. Circle is friendly. Strobe is jammer. Strobe to dash is under 35 km. HDD is 7 times range key. Radar to 160 km, IRST to 10 km. Stay low, but never slow.

I did, its the reason why I popped this thread. He popped a thread about discrepancy between stated torque for hover/skid height and in-sim torque. So my question to you, is how to produce such charts?

There are several versions of the same manual, one in 1986 (hardest to find), one in 1988, one in 1992! Which is the closest to our bird? I understand that the performance will vary because not all conditions were tested by company, so I am willing to try to sort of get the charts for DCS but I will use unlimited fuel and empty chopper as reference. I hope I can do this.

any way to display the current torque? like numerically, instead of reading it off cockpit gauge?

sort of a debug column?
