Holds (ugh)...

Whether it's because you're reaching the end of an instrument approach, have just popped out from the soup, looked up over the panel, and can't see anything that resembles where you'd want to land an airplane.. or it's because ATC needs for you to wait for a while

For consistent reference,, we'll use the hold in the approach we've been using.

I think I have the concept down with a VOR. You fly towards it and make the appropriate entrance procedure, then the second time you fly over it you make a standard rate to the proper radial. Either the assigned radial or the reciprocal depending on which direction you it it at. The vor needle will keep you on course when flying inbound to the VOR and you use your heading to fly the outbound?

However I have no clue how you would use an NDB or GPS fix. The needle only points to an ndb so would rotating the compass card to the inbound radial give you a accurate inbound course. (in a zero wind situation).

The other question I have is the video mentioned adjusting the outbound leg to the inbound legs time. How would you be able to calculate this. Is there some formula you use based on airpeed?

This is a topic I need to learn if I ever get radar contact so I don't have to disable holding :D.

EDIT: I just tried an NDB hold and I think It worked. I flew into the ndb, then back, made a standard turn to the assigned outbound and flew that with the heading indicator and flew back using the ndb. I didn't finish it because I was too excited to post this :). I am flying the defualt cessna.

Besides the fact I overflew the outbound by 3x and my altitude is all over the place did I do anything wrong? http://img268.imageshack.us/img268/8563/myfirsthold.jpg

I am using the missed approach procedure from this approach. http://204.108.4.16/d-tpp/0908/00443I1.PDF

You've got the general idea

Thanks for the tips, I will try them as soon as I can. This tutorial made holding alot of sense. Now I need to work my way up to more complex aircraft. It will probably be easier with a course and heading bug.
