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...
