I have a real problem with this question. I have my endorsement from Gleim and will take the written this Friday. Scoring consistently 90 or above. First time I have seen the question below. I realize an airborne VOR check must be within 6 degrees accuracy of radial selected. However, this question as I read it also ask status of the TO/FROM indicator. Only one answer has that status listed. The other part of the answer of a TO indication when OBS centered on 0 degrees when due south (180 degrees) is an accurate statement. Why am I wrapped around the axle here? Question: 4 When the CDI needle is centered during an airborne VOR check, the omnibearing selector and the TO/FROM indicator should read A. 0° TO, only if you are due south of the VOR. Answer (A) is incorrect. The airborne check is performed over points designated by the FAA or over specific landmarks, not only due south of the VOR. B. within 4° of the selected radial. C. within 6° of the selected radial.
