Home fuel advisory

Is there any way to turn off the home fuel advisory, or to set it to use the Carrier TACAN instead of a waypoint?

Practicing carrier traps, with still 4000lbs of fuel, I'm getting home fuel advisory messages every few seconds. You can cancel the master caution, and it will just deedle deedle again. Very distracting when in the groove, especially because it keeps coming back!!

I've tried changing the waypoint number for it (via the up/down arrows on the FPAS page), but because I have no waypoints in my system for my carrier practice mission, it doesn't do anything. I'm not even sure what it's using for it's home field, as I have no waypoints in the system...

Haven't done that yet, but I read that you have to box the TCN on your HSI page for the FPAS to take it over a WP.

Excellent question, I am facing exactly the same problem.

FPAS can calculate to TACAN but the home fuel and its associated warning are always to a waypoint.

Don't you always have at least one waypoint (#0)? If it's acceptable you can extend the refueling probe which will inhibit the alarm.

Waypoint “0” when at your originating airfield is fine but what happens when waypoint “0” is the carrier? Does the waypoint move with the carrier or get left behind as the carrier moves?

Should be static. Means, It doesnt follow the carrier.

Yeah, that’s what I thought. So, presumably this waypoint is what FPAS is using to calculate home fuel, which after an hour or two of being airborne, is going to be several miles away from the ship. 4000lbs seems high to be getting the advisory in this case though, and doesn’t explain why it repeatedly comes back every few seconds after cancelling the master caution...?

Yip, it's really annoying having to answer this alarm every few seconds during Case 1 practice. If anyone works out the solution I'd love to hear it.

I go to the FPAS page and hit the down arrow once by home. Changes it to "59" and it stops bothering me

It should be enough adding a WP close enough to the destination, Airbase or predicted position for the Carrier and change Home to the number of this WP that should be close enough to not trigger the warning.

Thanks for this post, it was driving me nuts a bit and thought i was doing something wrong on my bird setting. So in other words a quick workaround either in mission own created or on a server, is simply create a waypoint with the UFC of your actual location once on the carrier or the carrier's location when going to reach the carrier, so it'd fix the issue for a while at the speed the ship is going.

I just go to the FPAS page and increment the waypoint to the highest possible number.

Exactly. I've discovered that selecting any wp (in the FPAS page with the up/down arrows) that is not part of a sequence will deactivate the "home fuel" advisory. Thus I just press the up arrow from wp 0 to go to wp 59 (never saw a flightplan loaded up with 59 waypoints)

Cool thanks

The home fuel caution should be disabled with wheels down. WIP :)

this... also, just turn the warning volume down when practicing carrier traps... it'll save your sanity.

I rather leave warnings sound as is, so when Low Fuel and Bingo pops i'll hear it, as otehr said, quite simle to either select in FPAS highest waypoint or any which is not a entered waypoints with coordinates as this Home Fuel thing will warn according to the selected waypoint distance si if empty waypoint is selected, it'll simply not warn you.

What exactly triggers the Home Fuel warning? I've had it go off with roughly 8-9,000 pounds of fuel left, and not that far from the carrier ~20-30nm out. Even if it thinks I'm going back to the initial point of the carrier at the start I would still have a ton a fuel left.

Doesn't happen all the time, but considering it's the topic of discussion here, I figured I'd do a little investigating.

Fuel flow and speed I think.

What exactly triggers the Home Fuel warning?

The warning triggers when the system calculates you'll arrive at the 'Home' waypoint with less than 2,000 lbs reserve of fuel at your current fuel flow/rate, it disables it's self above 0.9 Mach but it's still fairly easy to trigger a false alarm, with heavy throttle use.

Ahh, makes sense now. Thanks for the info!

Oh this thing comes up all the time, no this is definitely not the way it should be, no way they had it like this on real planes IMO.

The home fuel advisory should never be enabled by default on waypoint 0 which is always there no matter what, spawning in mid air.

Not sure tho completely, what sparked me to this thread is that I just got a warning when I was setting it back to Waypoint 0 from just fiddling with it not even wanting it to warn me on any waypoint since I just used TACAN for the session, I was doing a range test from North Crimea to Batumi and I got the fuel warning halfway on waypoint 0, I thought what on earth i'm low fuel already? - this thing doesn't have an off switch in real life either?

It absolutely is like this IRL. Fuel management is one of the most important aspects of mission planning, advisories like this are safeguards for the aircrew. While they may be annoying are realistic and there for a very good reason. Unlike DCS you can’t just plop into a jet in the real world, often mission planning takes as long as the mission itself, and working out when these cautions happen is part of that.

This.

Every interview I have heard or documentary I have seen, pilots always emphasise how at the forefront of thinking and planning, fuel is the priority. Especially with Hornet pilots because of the relatively low capacity of fuel on the jet.

I had this advisory come up on catapult takeoff with new full tanks
