Ok, I'm a student pilot with almost 20 hours, I've taken ground school, and I've been playing flight simulator all my life. But for some reason, I just can't grasp the spatial orientation part of the TBAS. Now, I've never taken the test, but I've researched a lot about it and practiced the flashcards:

Could someone please explain what you're trying to do and why a certain answer is right or wrong? If you could use a specific example from the flashcards, that'd be helpful. Thanks in advance.

Flashcard shows red arrow in your direction of travel. The boxes on the right shows your point of view referrences. (ie A is straight ahead) you are than asked to find in which box an object would appear (form your point of view) If red arrow in pointing south and they ask for S box A would be checked.

If W is needed to be found than B is checked.

That makes sense, but for others it does not. For example, there is one flashcard that shows a heading of 090 degrees (east) and asks for the east carpark. Wouldn't the answer be C instead of A?

I keep thinking that whatever you're heading is, that's supposed to be "north" when it comes to your point of view.

Imagine you are looking down at a parking lot, heading in the direction the red arrow indicates. In your example, east. Since you are heading east, then the lot straight ahead of you is the East lot, which is A. C would be the west lot.

If you are heading east what is in front off you?

East! Box A is what is in front you box B is to your right C is behind you and D is to your left

So from your question E=A S=B W=C and D=N

ie if you are going east west is behind you C: south is to your right B: and north is to your left

Try this way there are four parking lots N, E, S, and W they are all serviced by an elevator that comes up in the midlle of the four parking lots. You step out of the elevator facing east where is the east parking lot in front of you, where is the west parking lot behind you.

Remember A is in front, B is to the right, c is behind, and D is to the left

Thanks to both of you so much! I didn't realize that the ground picture was already orientated for you. Thanks again!!

TBAS is important, but also remember that flight hrs are a bigger player now for PCSM compared to yrs before. You might want to get some more flight hrs under your belt to bump up your points, and I am betting it will assist in TBAS.

There is another reason to get more flight hours. If you have a PPL they currently waive IFS. Even if you don't have a PPL it will help at IFS.
