The reason I signed up to this forum was for help. I especially was stuck on the instrument checkride and was looking for a solution as to why I could not finish the instrument checkride. I have noticed that there is a lot of members who cannot find the solution to this problem. I finally managed to solve the problem and the following has worked twice for me. I would like to post my contribution to this.
After performing the missed approach and turning right to heading 160 you are instructed to hold on the 140 degree radial at seattle. (this is where I had the problem.) In order to get the instructor to continue with the checkride I found that the following solution. After passing the seattle VOR fly for 1 min on the 140 radial and perform the standard rate turn to the right onto the return leg of the holding pattern. Set your NAV1 to 323 degrees on the Seattle VOR and follow that radial over and away from Seattle to Nolla. As you pass over Seattle VOR the instructor should then inform you of your next instructions and you should be able to complete the checkride.
I hope this will work for others as it has done for me. I must have tried this checkride over twenty times before I finally completed this checkride. Next is to crack the Commercial checkride. I have a rough idea of the course to follow but need to refine it so as to make less errors. I am down to 4 errors for heading and altitude from over ten at the beginning.
