I followed Ardupilot instructions and Installed MavProxy, Cygwin64 on Windows 10 machine.
Also following this video
When I am at this step, I get this error message;
Asim T580@Asim-Laptop-Main ~/ardupilot/arduplane
$ sim_vehicle.py -f quadplane --console --map --osd
-bash: sim_vehicle.py: command not found
Why is not finding sim_vehicle.py command?
is it a path issue?
First time attempting and very new to it, so I am lost in the wind…
On windows 10 WSL is the way to go, anyway ../Tools/autotest/sim_vehicle.py ect should work. You can also connect misson planner using tcp and start the sim up with --no-mavproxy
AAAARGH …should I be using these steps…Setting up the Build Environment on Windows 10/11 using WSL1 or WSL2 — Dev documentation
Should I uninstall everything I just installed 
if its working i wouldn’t stress. Cygwin is a little more limited in what it can do, but for building and testing the main vehicle codes it basically makes no difference.
if its occupying a lot HD space I will get rid of it… Any special procedures to follow while uninstalling it…
Still same error;
Asim T580@Asim-Laptop-Main ~/ardupilot/tools/autotest
$ sim_vehicle.py
-bash: sim_vehicle.py: command not found
Directory contents show the file exist…strange
Also, within Mission planner, if I am using TCP, what would be the IP address to use? Default is 127.0.0.1 and remote is 5760 which technically should work…
Sorry, very new to all this…
So first I guess I have to set " First set up SITL for use with TCP .
In Mission Planner connect to SITL by selecting TCP and then the Connect button. Enter the remote host and remote Port of the machine running SITL . Mission Planner will then connect and can be used just as before."
Now how do you do that? 
have you installed python? With Cygwin you have to manually install the list of stuff on the wiki in the Cygwin installer.
The default mission planner IP and port are correct.
dah…using a different laptop the lab one has python for windows. Totally forgot…lol
by the way is the SITL server down?
I can’t run simulation under MP…
Working fine for me, latest MP beta. You have to install python inside Cygwin.
Linux doesn’t typically add the current working directory to the search
path.
I believe our environment isntall scripts typically do add that autotest
directory to the path.
In this case you want to specify, "run sim_vehicle.py from the current
directory, lile this:
./sim_vehicle.py -v ArduCopter

There is a script at /ardupilot/Tools/environment_install/install-prereqs-windows.ps1 that will automatically perform all the required steps to install and configure Cygwin,
