Somewhat of a newbie question but..

When I depart from a stand I have to resort to turning around by increasing my throttle and turning hard trying to not hit the terminal building 😳 😕

What I would like to know is how you request a tug to turn you around so I can taxi the rest of the way on my own.

Could someone also tell me how to request other ground stuff (like baggage, fuel, mechanics & the passanger ramp)

I thankyou in advance,
Phil
