Lesson 5: Stalls & Dive to Max Speed

Here you can discuss both spectrums of airspeed, from stalls to pushing the aeroplane to its maximum speed.

All goals done in DIVE., but only 40%. i missed someone?

Good evening sir. How we can check G gravity on sim? It’s not real live and we cant feel it on the sim. I try pass this lesson and the best result that I had has been 1.52 (dont know how). And lesson isnt pass.

Maybe its some bag? I take G1.45 but not past

Hello everyone! Martin with the instructor team here.

We have two separate discussions here:

  1. It is not possible to view the G-force in the simulator currently (as there is none in the Cessna in real life), and I agree it feels somewhat difficult to know how much force you are pulling, this since there is no bodily feeling like in real life. However, we want you to experiment and discover what is a small pitch up force, and it may take a few tries to get this right. Make sure your pitch input on your control device is capabable of giving small inputs, and be really smooth on the controls on the exit.
  2. I see one instance above where you have scored ā€œSatisfactoryā€ or better, but still failed. This is a bug that we are currently solving, and I hope we will have a fix out soon. Currently you need to score 75% or better to pass a manouvre, regardless of the given feedback levels.

Let me know if you have any further questions.

I’ve been trying to pass the straight stall test all afternoon, I don’t know what I’m doing wrong, the non-straight and dives are fine….I’ve compared my attempts with the Navighraph tutorial video and can’t see any difference. My stall horn doesn’t work with navigraph…..it works in the sim

The same for me - no stall warning in cockpit view in Navigraph while it works fine in free flight. It’s MSFS2024.

Thanks a lot for reporting this, guys. We are looking into the stall horn issue.

I’ll add to that besides there being no stall horn, the plane also exhibits zero buffeting like demonstrated. The only way to see the stall is because it’s fully developed.

I am using MSFS 2020. This lesson seems almost impossible to pass. If I recover from the stall as soon as I hear the alarm, the grader won’t detect my recovery. If I stay on the stall longer I end up overshooting the minimum loss of altitude. The turning stall is also hit and miss like this. Any advice from anyone on how to get the grader to recognize the stall on time and make it pickup the recovery?

It would be good to understand what point exactly is considered the start of the stall, for each the incipient and fully developed stalls. Basically when is the ā€œstartā€ altitude accounted for? And what speed is the point where we can start the recovery procedure.

If real life flight training my starting altitude is when I start the entire maneuver. I guess from the moment I am straight and level and pull the power out to start. Somehow I doubt there is a way the system is detecting this. So, which is it?

ā€˜Gordon for what it is worth…. the stall horn worked for me the first time I atttempted the lesson. But the next 4 times it did not. Almost impossible to meet the criteria, when you have to guess at when the stall is approaching. I did try to cheat by greater tracking of the speed, unfortunately, while focusing on that inside the cockpit instrument, I lose external vision, which impacts my ability to maintain the heading. And as for the turning stall, by the time I’m visually convinced I am in the stall I’ve already dropped so much altitude there is no time to recover within the lesson parameters. So, any quick changes will be appreciated as I appear to be stuck in this lesson for a bit. Unless we can just skip lessons?

  • FYI … I restarted Navigraph academy twice and tried the lesson in MSFS24, restarted the sim twice and tried the lesson. The stall horn never reappeared. I also tested a stall in the sim’s free flight mode and the horn sounded loud and clear. (hope this helps)

Hi everyone. So sorry you are all experiencing issues passing this lesson. We’ve detected that too many lessons seem to fail on our side too.

We’re working on solving the missing stall warning sound, which I think will make this a lot easier to pass for many of you.

As for the stalls not detecting or being too difficult; would it be possible for you to paste the URL to your individual flights, where these stalls have occured? We can then take a look on our side and see why detection did not happen as intended. (The url cannot be used to access your account).

Best regards
Martin

I hope these are the URLS you were looking for:

Flight #10 | Navigraph Academy

Flight #11 | Navigraph Academy

Flight #12 | Navigraph Academy

Flight #13 | Navigraph Academy

Flight #14 | Navigraph Academy

Flight #15 | Navigraph Academy

We’ve now investigated the issues discussed in this thread.

  1. With regards to the missing stall warning in MSFS2024, this is assessed as a bug on Asobos side. We are currently raising the issue on the dev support forum. We cannot unfortunately proceed here without help from the core simulator devs. If you own MSFS2020, you can use this to fly the session without issues in the meantime.

  2. As for the difficulty in passing this lesson, we believe the pass thresholds for the altitude loss have been too strict. It will be reduced in the near future. If anyone has issues passing the lesson, please reach out and we will manually assess your flights and pass them until further.

Looking at our data, we seem to detect most stalls accurately (looking at indicated airspeed as the assessment value). If you have particular flights where you think you stalled but did not get an assessment, please post these here and we will look into these.

Also, be aware that the techincal bug reports in this thread will soon be moved to the technical support forum.

Ok, so I managed to pass it with 87% score. My advice is that you do one maneuver at a time. Start with the straight stall and do nothing else until you see a passing score for that one. You only need the incipient one to pass, no need for the fully developed. The trick is to not spend too much time under the stalling speed, this will lead you to loose too much altitude. Also don’t delay adding power or again you will loose more than the altitude required to pass, push down and add power, do it almost simultaneously.

For the turning stall, you must be right on 68 knots power off descent before starting your turn. Do a 30 degree turn too, this will make it easier to actually stall. Start pulling up a few seconds after reaching the 30 degrees. Then once you hear the horn pull fully aft the yoke and immediately start the recovery procedure (pitch down, full power and wings level, then pull up as you gain speed).

For the dive, you don’t need to be any higher than 6000 ft. Just pull power back to 1500rpm and dive into at least 15 degrees down. Keep this down pitch until you reach 155kt, then pull power to idle and start easing out of the dive. Apply full power when you have positive rate of climb. You don’t have to get back to altitude, you can stop the lessons as soon as you start climbing.

I hope this helps others.

A couple of questions . How do you check that you passed the maneuver before moving on to the next ? AS far as I know you can only check your success after ending the flight.

And it’s my understanding that you have to pass all the maneuvers on a single flight, I.e. you can’t complete straight stalls, exit to see your score. Then startvanother flight and work only power dives.

Second questio how did you got the stall horn teams to work?

Yes you are correct. What I meant is that I focused on one maneuver only at first. So I would enter the lesson do a quick stall and exit the flight without trying anything else. Then see my score for that one maneuver. I would not pass the entire lesson of course. But at least I would know if that part is acceptable already. I did this for each maneuver individually to avoid wasting time and focus trying all maneuvers in every flight. Onnce I knew I understood them well I did one final flight doing all three correctly and only then passed the lesson. I hope that helps.

I have tried multiple times and I just can’t pass the stall lesson, not even close. Every other lesson I get at least 90% first try but for the stalls without horn and no buffeting all I get is feedback to be gentle with controls. I’m not yanking at all but being smooth and gradual yet the system keeps failing me harshly.

Hello,

Thanks for the feedback, we will look into this.

Well, I managed to cheat the system but mostly flying on the numbers instead of responding what happened and some additional suggestions for the procedure from chatGPT to work around the MSFS flight model. Solid pass now.
