Why does the ARJ have a dedicated APU when there are 4 APUs hanging under the wings? 😀

It is indeed the APU Inlet Door 🙂
I’ve noticed that before and often wondered what the hell it was ? Thanks for the info.

It’s the APU inlet door. You can’t have fire without O2.
For example, CH4+2 O2=CO2+2 H2O. But with not enough O2, the reaction equotation may look like this:
2 CH4+3 O2=CO + 4H2O
or
CH4+O2=C+2H2O
(CH4 is the chemical connection of natural gas.)
This actually hasnt has much to do with this, but it shows how contrails are made->water is a reaction product of burning.
