LNAV Reworking

With the release of the Global update, many new features were introduced such as the new LNAV feature, which essentially flies the plane on an established flight plan once enabled. This feature is proving useful within the community, with players engaging in long haul routes as well as small haul ones and is particularly useful as players can leave the simulator running while the plane is being flown by the autopilot. However, a significant fault in the feature is the way it functions, which may not seem game-breaking but more so unrealistic and in some cases can be disrupting to a flight. Another competitive flight sim on the mobile platform by the name of Aerofly FS 2 has implemented the LNAV system excellently. In fact, it is the closest simulator to replicate real world navigation systems and physics on the mobile platform although the game itself at the current time is lacking in content. This post essentially is a request for the reworking of the current LNAV system in Infinite Flight so that portrayal of real life navigation physics of that seen on commercial aircraft in the real world as well as in Aerofly FS 2 is seen in Infinite Flight. If Aerofly can do it, why not Infinite Flight? As it is difficult to explain with words only, below are some pictures, which display the navigation page for Infinite Flight and Aerofly FS 2. I will touch on the differences as well as how each system works in conjunction with the mechanics of their simulators.

So the first picture we have is what a typical flight plan on Infinite Flight may look like (which I created for the purpose of demonstration). As we can see, the route from way point R1127 to way point VIKYU is normal with just a straight line being the way to reach way point VIKYU. However, the transition from way point VIKYU to way point LOZIT (circled in red) is just another direct line instead of a curve, which is seen on Aerofly FS 2’s LNAV system. In accordance to how the simulator works, the aircraft, instead of following a curve to guide it into and out of a turn, begins the turn at the very last second, which puts it directly above the way point and a dramatic bank in the direction to the next way point would occur to ensure the plane aligns to the flight path given to reach the next way point. If this were to occur in real life, this motion would be a violent jolt. This not only is an unrealistic mechanic but it also causes the plane in high speed and low speed situations to, on occasion, not align with the flight path.

In the second picture we have a typical flight plan on Aerofly FS 2 (which again was created by me for the purpose of demonstration). This is where the difference in the systems comes into perspective. Circled in red is the transition implemented in Aerofly FS 2 once a waypoint is reached and a turn is required to follow the flight path for the next way point (TZZ). In comparison to Infinite Flight, the LNAV system and navigation page actually ensure that the plane has a smooth entry into and out of a turn, hence why a curve is shown compared to Infinite Flight’s straight line transitions. Just to the right of the curve is the actual way point indicated for the initial flight plan but instead of going direct to the way point then turning, which is demonstrated in Infinite Flight, the system creates a route to begin the turn before reaching the way point and ensures the aircraft is aligned with the small dot inside the star (which is the way point). As a result, the aircraft begins the initial turn a lot smoother and exits the turn to align with the flight path. This system is not only implemented into Aerofly FS 2 but also their previous flight sim Aerofly FS, as well as FSX, X-Plane 11 and in commercial aircraft seen in the real world. This demonstrates the attention to realism Aerofly FS 2 has aimed for and simulates flights to that of real world performance.

Apologies for this post being so long but it is very difficult to explain the issue without a visual representation and in-depth explanation on the differences. I hope this has challenged some of the members of the community as well as the developers to look into this issue a lot closer as perfecting this feature would not only improve the experience within the simulator, but further narrow the best options for flight simulators on the mobile platform to only Infinite Flight. To conclude, please up vote as well as spread this post to see this feature reworked and perfected in a coming update.

Happy Travels

Hi!

In order to post in #featres you need to be TL2, currently, you are not. Just be productive in the community and you will get there in no time!

I hope the mods don’t close this. It’s been a while since I’ve seen such a productive post.

Flight plans are displayed in IF as they are displayed on real life avionics equipment. No transition lines.
