VOR question

[backseatflying]

Im studying for a up coming Jeppesen ground school test and came across this question. How is the aircraft not east of the VOR? So far this stuff makes sense but not this question!

You are correct. The explanation is wrong. First off, it's not a 030 course selected it's a 300 course, but that's probably a typo (as the reciprocal of 030 wouldn't be 120). Given a 300 TO indication and the needle to the left, you are somewhere NORTHEAST of the 120 degree radial (but still SE of the station). Given the amount of deflection, you're probably on about the 115 degree radial NOT between the 120 and 210. East is the "most correct" answer.

Just a reason as to why I regarded Jepp as one of the worst materials to study with.

Thanks for checking on that! I was starting to doubt my fledgling VOR skills.

I agree entirely about the Jepp material. Has anyone sent a correction to the Jepp dept that handles this stuff?

For a part 141/142 school, it's a package that is easily auditable by the FAA and defendable by the school. I teach CS at a local university but take courses in the aviation dept. The online Jepp material is required for the private & instrument ground courses. A few years ago the school got into trouble for not being able to defend student progress nor the grades for the stage checks and was in jeopardy of losing FAA accreditation. Easiest and fastest choice was Jepp.

My biggest complaint with the current online Jepp material is the 3rd party Learning Management System (LMS). Jepp does the content, this other company provides the LMS and it's crap. Doesn't work on a tablet, looks lousy on a small laptop monitor, can't change the size of the font, can't change the size of the screen without losing content on the bottom or the right side. Best part? The audio is someone reciting exactly what is on the screen. I'm not in grade school, I can read. It's trivial to make 2-3 audio tracks play at the same time....

(Illustration 1) The VOR receiver has the indication shown. What is the aircraft's position relative to the station?

X South
O North
O East

(Correct)
With the 030* course selected, a "TO" indication, and a left CDI deflection, the aircraft is right of course, between the 120* and 200* radials. Therefore, south is the correct answer.

Yup -- "east of the station" is the best answer because you're between the 042 and 120 radials (any location more than 78 degrees off the radial would be in the Zone of Ambiguity and show an OFF flag, not TO), and that's the East quadrant. Hope someone tells Jepp they have it wrong.

I'll never use nor recommend Jepp study/test prep materials ever again.

My FAA test prep study guide had about half a dozen glaring errors in it.
