I am using ArdSim Library to make an autopilot. I am one Digital IO short for my project.
On the Nano's page, pin 27 is used to power the Nano with regulated 5V, but there is no mention if it will supply 5V if it is powered by the USB or external power (7V-12V) on pin 30.
RX and TX are used to communicate with X-Plane, D2 to D11 are used for switches, D12 and D13 are used for LEDs, and I am missing one output for the third LED.
I intend to use a 14001 Nor gate and a 7400 Nand gate to solve my problem, but those chips need power on Vss and Vdd. I checked the data sheets and they can't be driven from 3.3V.
I don't want to just try and see... and break something.
If pin 27 (5V) can supply the power, then I am OK.

No, not really...
Pin 27 is supplied with 5V from the USB connector. It (Pin 27) supplies nothing, BUT, you can tap off of it and get 5V when the USB is plugged in though.
But,,, AUTOPILOT, powered by USB, You're gonna need a lot of lift or a really long USB cable.

Not according to https://www.arduino.cc/en/uploads/Main/ArduinoNano30Schematic.pdf - this says it's tied to the 5v supply to the chip, which will be either powered from the USB or the external power (through the regulator). Assuming your nano conforms to the official schematic, that pin is directly connected to the Vcc pin of the ATmega processor.
