Joch1955 Posted March 14, 2023 Share Posted March 14, 2023 Picked up the module recently and having been slowly learning it. I have been practicing airfield landings to better understand how the "Trim" works. When on final approach to land (gear down, flaps down, speed around 130 kts, on 8 degree AOA, trim to be more or less hands off), the master caution lights keeps going on, but with no associated warning. I checked the manuals, but can't figure out what it is. I am thinking it may be related to the Trim or slow speed? Link to comment Share on other sites More sharing options...

Brun Posted March 14, 2023 Share Posted March 14, 2023 Hook bypass switch will make the AOA indexer flash if it's not set to 'field' and the hook is up. Been a while since I ran into that tho and I don't remember it triggering master caution, unless that happens at a specific altitude AGL?

Joch1955 Posted March 14, 2023 Author Share Posted March 14, 2023 Looked into it again and I think I figured it out, most likely candidate seems to be a low fuel warning triggered by the FPAS. As I understand it, the FPAS will trigger the Master Caution light when it calculates you will only have 2000 lbs of fuel until you reach your Home location as designated in FPAS. In the scenario I am playing, "Airfield VFR landing" on the Nevada map, you start with around 2200 lbs and land on the runway with almost exactly 2000 lbs remaining. In other scenarios where you start with more fuel, I don't have that issue. Thanks for the help. Link to comment Share on other sites More sharing options...

It should be triggered if it's condition you are describing. Edited March 14, 2023 by Tusky 1 Link to comment Share on other sites More sharing options...
rob10 Posted March 14, 2023 Share Posted March 14, 2023 Always check the bottom of the left DDI when the Master Caution goes off. Any cautions/advisories will show up there and usually give you an indication of what's wrong. 1 Link to comment Share on other sites More sharing options...

markom Posted March 16, 2023 Share Posted March 16, 2023 It's #1 most annoying alert in hornet :-). I especially hate it when it starts beeping while I'm trying to land. Like... I KNOW, I GET THE IDEA DAMNIT. STOP IT. I also can't seem to find a reasonable way to silence it, but that just may be me. Link to comment Share on other sites More sharing options...
Sarge55 Posted March 16, 2023 Share Posted March 16, 2023 Go into FPAS and change the Home waypoint to an unassigned waypoint. That should stop the caution showing up. 1 1 [sIGPIC][/sIGPIC] i7 10700K OC 5.1GHZ / 500GB SSD & 1TB M:2 & 4TB HDD / MSI Gaming MB / GTX 1080 / 32GB RAM / Win 10 / TrackIR 4 Pro / CH Pedals / TM Warthog Link to comment Share on other sites More sharing options...
TonyG Posted March 16, 2023 Share Posted March 16, 2023 Ongoing bug that is still not fixed. Still 1 Link to comment Share on other sites More sharing options...
SickSidewinder9 Posted March 18, 2023 Share Posted March 18, 2023 (edited) Really annoying that it's not fixed yet. It's not a simple if/then or try/case to add? The problem with setting to an unused WP is that it breaks the FPAS and then I don't seem to be able to reset and use it again. Or I can't set a new Home. Whichever it was. Functions break.

Tholozor Posted March 18, 2023 Share Posted March 18, 2023 (edited) Home waypoint selection is only available when the FPAS is able to calculate the HOME FUEL caution, otherwise the home waypoint is crossed out and selection arrows removed (this is correct as-per the NATOPS). The HOME FUEL caution logic should not be active with weight-on-wheels, the refuel probe deployed, or for 5 seconds after a new home waypoint is selected while the logic kicks back in. "Unused" waypoints are still technically viable coordinates, as all zeroes would be the position where the equator meets the prime meridian. Since the waypoint is so far away, the FPAS loses its ability to calculate HOME FUEL, as the remaining fuel would be far below what the aircraft can carry (at least in regards to the location of the theaters available to us in DCS), and home waypoint selection becomes unavailable. One main reason why HOME FUEL is so common on landing (that I've noticed) is due to the power corrections needed to maintain a smooth glideslope. The fuel flow rate fluctuates rapidly, causing the FPAS to reassess the HOME FUEL caution constantly (depending on the home waypoint location and current fuel on board), resulting in the calculation to bounce above and below the 2,000-pound threshold, triggering the caution over and over.
