In the airplanes I am familiar with, a red GS flag when the VOR receiver is tuned to a valid ILS frequency, means that there is no valid Glideslope information. When the glideslope information is received, the flag disappears and the needle becomes active.In the Carenado C182, the red GS flag comes on when the glideslope information becomes available and the needle becomes active. (On my system, at least).Are other users experiencing this? And is it correct, or not?

Need screenshots to help, I'm sure not going to spend 20 bucks on a 182, I'll try and help though if you post some shots.

Here are two shots, both with ILS frequency tuned...First with Glideslope active, Second with no Glideslope.http://forums.avsim.net/user_files/119120.jpghttp://forums.avsim.net/user_files/119121.jpg

Bump...I am basing my question on Pilot IFR guides that emphasize to only trust a Glideslope Indicator "when no flags are present".Does anyone who is familiar with this Cessna IN-386A (I think..) VOR / GS indicator know if this instrument is designed differently?

Hi Bert,I'm in way over my head here but that's never stopped me before so here goes. When I worked on real-world avionics systems (admittedly that was almost 40 years ago), the flags were really little flags that "fell" down, usually, from the upper left or upper right corner of the gauge and had the word "OFF" printed on them.What I seem to be seeing here is an activity indicator that may even be a light that says "GS." That would not intuitively mean the same as an "OFF" flag to me. Now if I were designing that gauge and if it worked as I think it works, then I would have used a color other than red for the "GS" indicator.I'm interested to know if the red "light" on the NAV2 gauge ever extinguishes and if so, when.R-

Ron,The VOR2 red NAV flag drops when a valid NAV2 signal is received, and in its place, a TO / FROM arrow appears.Here is a picture of a real world C182 (in powered down state?): http://forums.avsim.net/user_files/119238.jpg

>Bump...>Does anyone who is familiar with this Cessna IN-386A (I>think..) VOR / GS indicator know if this instrument is>designed differently?Yep. I am quite familiar with the IN-386A.If you are seeing a red flag it means the head is not recieving a trusted signal or anyone at all. Jim

Hi Jim,I have tested this gauge in a few different situations. The Nav flags for both the omnis show when there is no signal or power is off, this changes to a to/from arrow when you are receiving a valid VOR signal. If you change the autopilot input to GPS the Nav flag reappears and the course selector is no longer active, which is in keeping with all other omni heads I have seen in MSFS. The GS (glide slope) flag is a curious one because it only shows if you are receiving a glide slope signal in the sim. It doesn't appear when power is off or you are receiving just a VOR or localizer signal. This appears to be in error as the real life photo above shows a cold and dark panel with the flag showing (which is what I would expect to see). I need to do some more testing to see if the bc (back course) light actually will work when tracking a localizer on a back course, it doesn't when back tracking on an ILS. There is also the arc light which doesn't appear to function in this simulation. It was a neat feature in the real gauge but I don't think anyone has implemented this in the sim yet. I am taking your quote Jim to also mean that the GS flag operates in the same manner as the Nav flag, which in this simulation is reversed.Regards,Zane

Hi Zane,I am simply answering Berts question which was should the flag be showing when on glide slope.No. It should not be showing on a 386. And neither should it be on anything else I have ever flown. In real life, you could indeed have a live needle and a flag up, but that means that something isnt quite right with the head or signal and it should not be trusted.Those flags are there for a reason on both GS and LOC. If you have a live needle and no flag, you are good to go. If not, procede with caution or don't procede at all.Jim

Thanks Jim,That is what I thought. I have a message in to Carenado regarding this, I am looking forward to their response.Zane

>Thanks Jim,>>That is what I thought. I have a message in to Carenado>regarding this, I am looking forward to their response.>>ZaneI've recieved no response so far to a pair of e-mails I sent them, including one about the VC Nav 2 bug.

I have just got a response from Carenado and they are collecting information about the radios, omnis and lights and will be issuing a patch as soon as these are sorted out. These are all very little issues in a rather nice and otherwise well thought out add-on that is working flawlessly on my system.Zane
