Hello janagirl,
one possible solution could be.
1. speed up to 50, have your nose to 15 before you speed up, just to be safe and so that you don't have to deal with it later.
2. when you here a number or a combination of letters and numbers either from the left or right, turn asap towards the direction you heard the number in with ctrl left or right arrow again depending on where you want to turn.
wait for it to say east if you turned right,west if you turned left. after that, speed up to your current take off speed as required by the flight you are flying.
check with z whether or not you have taken off (numbers greater then 0 indicate that you have) after that, and if you have,retract the gear and the flaps, wait for it to say take off successful,and then you can speed up,turn towards your destination and so on. oh and, don't forget to level off after 500 or so.

Hi,

leveling off means that your nose is at the angle 0 so that you aren't pointing up or pointing down,making your aircraft go higher or lower respectively.
in free flight you could go where ever, but in missions you'll be given destinations where you are suppose to fly at (press a or shift a to check that), press ctrl f8 to bring up a list of airport sorted by their distance to you, choose the one you want to fly towards, after you have done that. pressing N will tell you where and by how much you need to turn so that you are pointing towards your destination airport. I.E 32 left will mean you need to turn 32 degrees to the left. 3 times shift left arrows and twice left arrow should acomplish that.
this may or may not change during flight,so keep on checking now and then by pressing the n key.

one thing I forgot in my last post, after you are airborn, that is taken off the ground, make sure you are heading either east or west wherever the runway was I.E to your right or left, press ctrl left or right arrows to snap to the nearest cardinal direction heading.

Hi,

Don't be sorry about asking questions as long as you have read the docs that are available and the ones that come with the game, and even after that you are left with doubts, its always a good idea to ask.

The aircraft collision happens because you are not following the directions given by the ATC, I.E if it tells you to descend to x y z, do so. if it tells you to climb up to x y z height, do so.
Always make sure your frequency and transponder codes are up to date. if you press f and it just says a number without a prefix of new then the frequency is up to date. if you press space and here no code such as scquock 4 2 3 4 whatever  the numbers,then your transponder is up to date,too.
If you are still facing the collision issue after you have made sure of all this,then your ATC files are probably screwed up. just get the latest from the website.
If that doesn't help, write back on here and we can come up with new suggestions for you to try
