![]() This reverses the display and inputs to enable the instinctive tracking desired. ![]() Hence having to turn away from the needle to close.Īs said, the OBS has nothing to do with ILS, and the only cure for this reverse command is a BACK COURSE switch found in some aircraft for ILS indicator, Flight Director or autopilot. However, the runway, on this heading, is now on your left. (This will apply whether you are north or south of the field, if there is a useable back course - it is the same signal.) If you are heading south, and still off centreline and to the west of the field, you are still in the same signal area and the needle remains on the right side of it's dial. If you are heading north, turning towards the needle will take you towards the centreline. Going right back to basics, if you care to consider a runway due north/south, with a LLZ on the 360 inbound, there is a signal which predominates to the west of the field and which deflects the LLZ indicator to the right side of the dial, and another signal predominating in the east which deflects the indicator to the left. Vandelay, nobody seems to have answered your question as to why the raw ILS indicates in reverse when inbound on a back course, and why it can't be cured by the OBS. (And I am cognisant of the twaddle going on re that title on another thread.) That is, the runway QDM associated with that ILS. ![]() To any wishing to understand how to fly an LLZ on HSI whether inbound or outbound, on the front course or the back course, there is only one setting EVER for the HSI COURSE setting - the front course track. The HSI will always indicate correct displacement towards or away from the LLZ irrespective of heading or position, provided the front course is set. Doing so will reverse all the indications of the LLZ. There is NO application for setting back course LLZ track in the COURSE setting of an HSI.
