what is inclination + question on career

I'm 2.5 years late but I wanted to let any others struggling with orbit inclinations that you're supposed to be using a formula to deduct the correct launch angle to achieve it, here, I'll explain. The launch inclination formula goes as follows, Cos(i)=Sin(A)Cos(O) where i will be the orbit inclination that you want, A will be the launch inclination (The angle that you launch at), And O will be the inclination of the launch pad.
Now to the younger players don't get freaked out, I'll explain
Say you want an orbit inclination of 30 degrees and you're launching at DCS pad which has an inclination of 0 degrees since it's situated on the equator, you'll plug these into the formula which will result in this: Cos(30)=Sin(A)Cos(0), you may recognize that this formula is basically just algebra, simply think of Sin(A) as x and solve, we bring sin(A) to the left of the formula and divide Cos(30) by Cos(0) which will look like this: Sin(A)=(Cos(30)/Cos0), (USE A CALCULATOR TO SOLVE THIS!!!), one this is solved you'll get the value of A which will most likely be a long string of random decimals, simply plug them into inverse sin (sin-1), this will look like
sin-1(0.8860254038) which will result in an angle of 60 degrees meaning that in order to get an orbit inclination of 30 degrees whilst launching from DCS pad you'll need to make sure that your inclination of 60 degrees (on the orange circle in the nav ball).

This is how I eyeballed it. Launch from Village Pad roughly SSW, that gets you to about 70deg. The cheapest way to change inclination is at your slowest point and when combining with a climbing burn. What you want to do is burn at either ascending or descending nodes to increase altitude to 1000km and add a bit of normal component, but not too much. This will get you to about 85deg. Now your APO is at one of the nodes so do the rest of the normal burning with your circularisation. If you miss the inclination then it's still cheap to adjust at that kind of height, but you have got some free boost by combining with your climbing burns.

@Toinkove thank you

@Toinkove thats what is killing me, i dont have that unlocked yet. this job came earlier then i needed it to.

@YaMomzBox420 if its the planet view, where you can use the burn nodes, i get that.

See that's kinda the issue. I did read about it and tbh I didn't understand it. I newest and the fact, like you said it's orbit relevant to the equator. A lot is lost to people who are very bad at math, we need the "Juno for dummies" option when it comes to flight and things like this. It makes people like me (even thou I used algebra at work for 20 years) who get frustrated and will just walk away because we don't grasp that aspect of the game. That would be a real help for people who want to play because it's fun, but are too frustrated with the overly complicated mechanics of the game.
Maybe like a stupid, normal, hard, rocket nerd settings would help. I don't mind playing and figuring things out but when I try abs research how to do things like this, it requires a lot if time and tbh most people won't/can't dedicate that much to a game. Life just gets in the way.

So, it sounds like you should probably look up stuff like orbital mechanics and the Kepler Orbital Elements(trust me, the basic idea is easy even if the math behind it isn't). Most new players aren't gonna have much knowledge on the subject, but that's part of the point of the game: learning about the physics and stuff involved in spaceflight. You just have to keep trying and look up stuff that you have problems with(also, continue to ask questions here and/or the discord server).

Now, to answer your question:
Inclination is the angle of your orbit relative to the planet's equator. If inclination is 0° then your orbit is perfectly around the equator(from west to east), if inclination is 90° then your orbit goes from pole to pole(south to north). The thing is, inclination can be anywhere from 0° to 180° depending on the direction of orbit over the planet. 180° is the same as 0° except in the opposite direction(east to west instead of west to east).

For a 100° inclination, you'd want to launch your rocket at either 100° or 280° on the nav sphere(both will give you the same inclination) and hope you don't need to adjust it much(depending on where you launch from, you might have a bit of difficulty getting to the correct inclination). If you do need to adjust things, you can use the burn planner to make things easier, but you'll probably want a tutorial on that as well if you're not familiar with how it works
