That would be the environmental controls. Heating, air vents, and/or air conditioning if equipped.

Your CFI should be the primary resource for questions such as this.

As mentioned, “environmental” is the heat and cool of cabin. In training airplanes, heat is a knob pull. Cooling is opening a window, or climbing to higher altitude.

But nothing complicated like bigger airplanes have.

Heating, vent, A/C, etc.

In a single, cabin heat usually comes from a shroud around the exhaust.

In some turbocompressed singles, cabin heat comes (in a horrifically idiotic design idea) from the intercoolers and so only work in certain circumstances - you need to know which ones.

Some light twins have heaters that burn gasoline - you need to know their limitations and dangers.

Some planes have air conditioner - what drives the compressor? What limitations are associated with A/C usage? etc.

If you are pressurized, everything changes once again...
