Arm/Disarm Switch and Companion Operation

Hi maybe someone can help me, before i test it next week:
Im wondering how the Arm/Disarming with a switch is effected by a companion and auto flight.
If im on the Ground and the Switch is disarmed can i still start a mission from the companion ?
And if i then take over Manual control i have to toggle the switch to turn the motors off ?

Thanks,
Daniel

Yes, you can arm, change the flight mode to AUTO and start the mission from a companion computer. What is it that you mean by the switch? Hardware safety switch or switches on radio controller? From your transmitter, when you change the status of the switch assigned to flight mode changing, if you change the mode for example to LOITER, you get control of your vehicle.
