A GA pilots perspective.
The four H's that contribute to lower performance of any aircraft:
Hot
Humid
High Altitude
Heavy (this is your payload, so it will not affect a P3 unless you mod it)
These all make your aircraft work harder for the same performance. Hot is part of what is called Density Altitude, as air gets hotter it is less dense so a prop has to work harder to create lift, it is as if you are at a higher altitude, your MR is less efficient. Humidity also effects performance of a propeller (and an internal combustion engine, this of course does not apply to a Phantom).
Batteries also don't perform as well when it is hot (or very cold).
So all in all the H's will effect the performance thus the range of a Phantom just like any aircraft.
Some tests will tell you how much, you could come up with a chart to show performance relative to density altitude and humidity.
Fun project, I just don't have the time...
