The way it's suppose to work is once they are activated with that personality, it does an inventory check for the "Subway Token". If you have one, it will take the token out of your inventory, then attack everything else in site but spare you.
I don't know whether it's a one time event, or would require more tokens upon revisiting the location later.
However, I've heard a lot about it being bugged at the moment and not working right. If that is the case, then a patch is set to be released this upcoming week. Hopefully that will be one of the fixes.
My recommendation for the robot is to set the personality to Law Enforcement, and keep your weapon holstered. Whenever enemies come out, run behind him. He will destroy whatever is around. If at any point he is destroyed, then step in and finish off the enemies. This way he never attacks you unless you draw your weapon, and it will save you ammo since he's killing off enemies.
When one is up against raiders they seem to be able to handle a few. If your lucky 5-10 at the most.
Ghouls they seem to be handle around the same number. Different people may have different results.
I have new information based off of new experience, and research.
I found some information at the following links:
http://fallout.wikia.com/wiki/Protectron_(Fallout_4)
I have tested this. You have to have a Subway Token in your inventory once the protectron is activated with this personality. Once the coin is requested, you have exactly 8 seconds to comply. In order to do this you need to press the action button immediately after he requests the coin, within 8 seconds.
You can pick pocket the coin back from him, but the next time he see's you, he will request it again. This information can all be backed up by the above URL, and a YouTube video showing this in action.
I have also verified this from personal experience within my own game as well.
The other answers supplied were very helpful, but didn't state the best solution which, in the words of Charlie Sheen, is
"Drugs."
Agility points help flight and action points help duration.
Per all my testing the height appears to be capped. (At approx 20 meters; using very rough vertical measurement by setting POV in fixed position and using reference features on buildings, etc.)
The total ground you can cover, however, depends on thrust management.
I was able to fly from the big island in bottom right corner of map (the one you can occupy, forgot the name) to the shore (near the old refinery/dung farm which looks like shortest island-mainland distance). It's been a while since I played FO4, so going from memory for now..
Here is how I get super long (but not high) flights with power armor jetpack:
- Max natural agility (perks + bobblehead)
- Agility paintjob on armor
- Food items that grant bonuses to AGI and AP (deathclaw steak, mole rat chunks, cooked softshell meat, and maybe a couple others, I think.)
- Drugs that grant bonuses to AGI and AP (usually carry x100 jetfuel and hotkey it.. constantly addicted to Jet :D )
- Maxed Perks that increase power armor efficiency and movement speed (Though I have not yet confirmed that this has any effect; just stating that I had these before even crafting the jetpack; need to test with different unbuffed char next)
- Hotkey Ultrajet (although Jet works pretty good too since you can quickly regain the "high" with hotkeys)
- Make a running jump, and use Jet as you are running or jumping.
- Focus on distance, not height. The trick is to manage thrust carefully, tapping jump key only as needed, NOT holding it down. This is sorta possible without jet, but much easier while time is slowed. If you run out of jet, take some more! (Yeah, you'll get addicted, but don't worry! Addiction is a joke in this game compared to the previous ones; 4 diff ways to cure it. Or get perk where you never get addicted to chems.)
Also note that Jetpack + Quad-barrel Missile Launcher + Jet = Archangel of Death

"And" gates and "or" gates are extremely simple, but I haven't found a way to make a "not" gate (think the inverter in minecraft) necessary to create more complex circuits. Anyway to make an "and" gate, create 2 switches as your input and wire them in series to an output. (like a lamp or pylon tower)
Generator > switch > switch > light
when (and only when) both switches are on, the light will turn on.
Also, "or" gates are the same except wired in parallel rather than series.
