I found out that not a single helicopter has range long enough to reach nearest friendly base in my last playthrough, so i started wondering if the range is set up correctly.

We have UH-1Y, MH-6,UH-60, AW109 CH-46E and V22.

From what i was able to extract from reddit 1 square should be between 1 and 2 meters closer to 1m. Lets say it is 2m to be safe. Standard map is 250x250 that would be 500mx500m lets say the helicopter is going diagonaly so the longest distance. If i remember Pythagoras correctly that should be about 707 meters.

I was too lazy to look deeper into it, but from the data i found about UH1Y maximal range drops by about 10% while loaded. It is probably more for bigger helicopters, but lets stick with that. You do not want to crash so lets say that they keep about 10% as emergency fuel so lets subtract about 20% from ranges, that are on wikipedia, because i am too lazy to find another source.

So that means:

UH-1Y range 241 km so 241 000/707 = 340 - 20% = 272 Tiles
MH-6 range 430 km so 430 000/707= 608 - 20% = 486 Tiles
UH - 60 range 583 km so 583 000/707 = 824 - 20% = 659 Tiles
AW109 range 932 km so 932 000/707 = 1318 - 20% = 1 054 Tiles
CH - 46E range 1018 km so 1 018 000/707 = 1439 - 20% = 1 151 Tiles
V-22 range 1 627 km so 1 627 000/707 = 2301 - 20% = 1840 Tiles

Lets edit it a little so it looks better so

UH-1Y = 300 Tiles
MH-6 = 500 Tiles
UH-60 = 650 Tiles
AW109 = 1 000 Tiles
CH - 46E = 1200 Tiles
V-22 = 1800 Tiles

Lets compare it to what we have in game.

UH-1Y in game 80 acording to me 300 (375%)
MH-6 in game 60 acording to me 500 (833%)
UH-60 in game 90 acording to me 650 (722%)
AW109 in game 130 acording to me 1 000 (769%)
CH-46E in game 110 acording to me 1 200 (1090%)
V-22 in game 90 acording to me 1 800 (2000%)

Ok, the range was probably done with some balancing in mind so lets cut about another 50%?

UH-1Y = 150 Tiles
MH-6 = 250 Tiles
UH-60 = 350 Tiles
AW109 = 500 Tiles
CH - 46E = 600 Tiles
V-22 = 1000 Tiles

Simply the range of helicopter should be longer

There is surely going to be some mistakes in my math, but it should be usable enough to demonstrate, that the we should at least double the range of helicopters.

I was looking only to transport helicopters, because i only use them.
