I know it's not good, seeing I just got started and have had a limited budget. I don't do Open for now so that isn't an issue.Erm, I mean no offense, but this is bad outfitting.
In order to not die hauling cargo, you either need speed, or shield/hull tank. (or much more piloting experience)
You have neither. (219/290 top speed, 58 shield strength, stock armor)
Things that would help: 4A Thrusters, 4A Shields or 4C Bi-Weave Shields(If you were playing in Open I would also suggest a MRP and ECM)
The fact you have ADC and SCA equipped however, makes me think you're probably flying incredibly incredibly slow, both in real space exiting space stations, and while traversing supercruise, which seems like the real problem. (With better piloting skills, even this unoptimized ship should be able to get away from most NPC pirates)
Are you letting the docking computer fly you out of stations? If so, as soon as it lines you up with the mail slot, you need to take manual control and put all pips to ENG, and boost directly away from the space station to get out of mass lock as fast as possible, then engage FSD and begin lining up the jump. If you begin taking fire at any point, pips to SYS, and boost towards your jump destination. If you are truly a "Harmless" combat rank, it should be rare that you are accosted by pirates fast and large enough to mass lock you.
Now a brief explanation of navigating in Supercruise:
DO NOT JUST POINT AT A DESTINATION AND USE SCA STRAIGHT AT IT.
This is SLOW, SLOW SLOW!
Pirates will catch you, and make your life more difficult.
Now a more in depth explanation of navigating in Supercruise:
You travel faster the further out of any gravity well you are. Stars and planets(among other things, I think) create gravity wells. When you approach a planet, you'll see rings expanding outward, this signifies you are entering its gravity well, which will begin slowing you down.
When you first jump into a system containing your destination, aim directly away from the star, avoiding any gravity wells you see to pick up speed. Once you are moving at a decent speed, then begin aiming towards your destination, again avoiding any gravity wells between you and the target. With nothing be clear space between you and your destination, now you are free to engage SCA(if you must).
Others have already given advice on how to deal with interdictions once they occur, but I'll add, flying in a corkscrew pattern towards your destination makes you much harder to interdict, and once you learn to spot threats on the radar you can easily avoid ALL interdictions, however this strategy requires not using SCA, or at least not relying on it entirely.
As for experience flying, indeed I do have experience. I used to work on US Navy fighter jet simulators, put in plenty of seat time to understand flight, it was my job, and I had to know how to fly. Handling an aircraft is not a problem. What is needed is to know how these video game aircraft handle, what it can do, and what it can't. If I'm out-equipped and out-gunned, it doesn't matter. I am Harmless, only because I carry no weapons, and I've never engaged in any combat.
My current top speed is 217. I know, it's slow, but it's what I have for now. Thank you for the upgrade suggestions.
I also have a lack of knowing who knows what they are talking about and who doesn't. Lots of "experts" in these forums that aren't experts. I agree better engines and shields is good. I just recently got an understanding of how the priorities work so I can manage power use. My current engine is doing decent now that I got that adjusted but runs a tad hot.
Sorry, I think it is a bit arrogant to say "with better piloting skills". You don't know me or what skills I have or don't have, you are making assumptions.
I started out the game flying manually, entering stations, landing, etc. All manual, then I discovered the flight assist recently. VERY cool auto docking.
What you suggest sounds like speeding within range of the station to break mass lock.
Yes, I understand gravity wells. I've seen the little message pop up. Thanks for the tip. I know what the effects of gravity are.
I always turn away from the star when I arrive to avoid heat, and as soon as I make a turn and accelerate, I do a D scan, and head for the next jump.
Corkscrew? I guess if it works in the game. From my experience in air combat tactics, that would be suicide in an aircraft, WAY too predictable.
Thanks again for the tips. I'm sure you mean well. Just try not to make such assumptions next time.
