Just Flight Piper PA-28-161 Warrior II

Hello, Does anybody else have a problem with the GPS needles on NAV 1 not working to intercept and track courses or shoot RNAV approaches?

For those that missed it, we released a flight model update for the Warrior. It should be released on Marketplace later this week.

v0.3.9

  • Improved low-speed handling characteristics

  • Improved stall characteristics

  • Added new MSFS ground friction support

  • Added CFD support

  • Improved trim sensitivity logic - Elevator trim is now less sensitive by default

  • Added trim sensitivity slider saving between flights

Nice, but how about the other PA28’s like the ones in the bundle? =)

The PA28 Arrow III and Turbo Arrow III/IV are coming next.

Great news! Thanks for the updates!

Awesome, what a nice surprise to hear Arrows are updating soon. I’ve been tinkering with the flight model to implement the new gear parameters myself. Curious to see how different the proper implementation is compared to mine.

Thanks for the update! I took it for a couple quick flights, and it definitely feels smoother, I think, especially with calm weather. With a 10-knot live wind, I found the airplane to be a real handful. It could be unresponsive on the controls, but then could make sudden large moves as I manipulated the yoke. I went around a couple times because of it and had some real scary flares. Turning around on the runway was also extremely difficult until I got a knack for it as there seemed to be an extremely strong weathervaning effect.

Anyway, it’s improvement I think, but I still find this massively harder to land than our club’s PA-28.

PA28’s coming over to 2024?

Yes, all our existing aircraft are going to come to 2024.

Does that mean made compatible with fs2024 or will you upgrade them to have all the features of 2024?

Compatible to begin with, then we’ll be evaluating what upgrades are possible in 2024. At the moment there doesn’t appear to be much in the SDK to indicate significant new features for aircraft.

That’s good to hear.

Shouldn’t the new SDK allow for a much more detailed fuselage and wing shape for the CFD calculations?

I am not seeing how better CFD allows aircraft to display significant new features.

It is improving an existing feature not giving us new toys to play with.

Has anyone experienced the ā€œcatastrophic failureā€ when attempting to install the update? I contacted JF support and, although very responsive, none of their suggestions have yielded success. Really enjoy flying this plane but made the mistake of uninstalling the previous version now I’m left sad.

The latest update installed without issue for me. I don’t think uninstalling the old version ahead of time would cause much a problem for a new installation.

Have you tried the IT Crowd stuff yet? Have you tried rebooting your pc? Have you tried downloading a new copy of the installer?

Flew the updated Warrior last night. For disclosure and perspective, I have several hundred hours in Warriors (plus several other PA28 variants). Here’s what I found:

The good -

  • It felt very stable in pitch, much more than it was in the past.
  • Trim sensitivity felt spot-on.
  • I did a few steep turns and had to use opposite aileron to prevent the plane from overbanking - that’s excellent! The steep turns felt fantastic.
  • Slow flight felt very appropriate.

The meh -

  • It was not easy to find a lateral (roll) sweet spot. Real planes can be that way, too, though, and I know yoke feel/setup plays in. I just felt I shouldn’t have to be so hands-on oscillating back and forth through wings level.
  • When performing power-off stalls, the behavior leading up to it was good, but I still got a violent wing drop (either direction) during the break. I think that’s a limitation of the sim, though.
  • The textures on the vac, alt, oil annunciators when lit are blah. Not a show-stopper, but looks less than pro
  • Like @SkipTalbot observed, something felt off in the controllability right above the runway. I didn’t have any major excursions, but it felt like there was a step down in sensitivity. I also floated a long way (but it was at SMO with really bad trees at the end of the runway, so wasn’t the most stable approach), but my speed on final wasn’t that fast. I was able to keep the nosewheel way off the runway down to a speed that shouldn’t have allowed that. I’ll have to test more with better intent.

The bad -

  • The weathervaning on the ground. A 6 knot wind shouldn’t be able to (slowly) flip the plane around 180°.
  • I simply could not get it to turn away from a 20-knot wind (at a different airport), even with differential braking. That’s a little overdoing it.
  • There’s still a fairly solid nose-up moment when flaps are applied, like it’s a 172. Again, I think that’s a sim limitation. In real life the nose pivots down and you get a feeling of lift from the seat of your pants when each notch of flaps are added.

The bugs -

  • The brake pedal animations didn’t seem to be working.
  • Also, for some reason all the trim axes are reversed in Just Flight PA28s. I always have to flip them compared to my other aircraft.

All in all, much much better. The corrections made to pitch make it flyable again. Can’t wait for the Arrows to be upgraded!

This is a never-ending argument, and one which I can only sit and watch having never flown a Warrior in real life. Closest I’ve flown any decent hours in is probably a Socata Rallye, which behaves as you describe and also feels like you’ve just dropped anchor! Also, aerodynamically it should behave as you note. However, since first release of the FSX version there has never been agreement between real-world PA28 pilots (yes, we have checked!) Some say it pitches up, others that it pitches down and even beta testers whose pedigree we know will not reach agreement. See the JF forum for more examples but:

I cannot make it do both, there are more saying it should pitch up than down :man_shrugging:.

I can decisively say the nose pitches down initially and immediately, but resumes a few seconds later. But what also happens simultaneously is a change in the center of pressure that also makes the entire plane rise a bit as well as decelerate. You’re controlling and retrimming throughout.

I have videos of my own, but I don’t share them. Here’s a fantastic demonstration of it from someone else. Right about the 2:13 mark as well as other moments:

I’ve just been digging through the flight_model file, comparing 0.3.8 (left), with the new 0.3.9 version (right).

The htail area appears to be reduced to 0. Perhaps a stabilator thing?

Looking at the ground handling options, crosswind is now felt at all speeds due to the ā€œ-1000ā€ values:

For the new contact ā€œup toā€ speeds, its 130knots for the main gear, and 30 knots for the nose wheel. Speeds above that mean it reverts to the ā€œlegacyā€ model, but I’m unsure whether that means those values that appeared in SU13(?) ā€œground_crosswind_effect_max_speedā€ & ā€œground_crosswind_effect_zero_speedā€, or whatever we had before that.

If it’s still weathervaning too much, this is likely where the problem is.
