It seems to me that there are several things missing from the Icon A5.
Let me start form the thing that is NOT MISSING, but should have some tweak:
->The real plane has a noticeable weathervane effect, when in water. That means it “turns on its own against the wind”. That is why people make silly YouTube videos titled “My Icon A5 doesn’t turn today, wtf?” That is because those people were playing in live environment and that particular day, there was a lot of wind, that made weathervane effect even more serious. They don’t get that. They think it is a bug, when in fact it is just the live environment simulation doing it’s job. Plus the fact that those people are unaware of the water rudder feature of the Icon A5. I sincerely hope that the studio can pick up such uneducated feedback.
That being said the Icon A5 needs:
Some better water rudder authority in the water, cause it seems to me that Icon A5, has so much weathervane effect modeled, that it is uncontrollable even at 5-10 knots winds, which I am sure that the real one can handle.
Landing gear down when in water. The (easy to find online) Icon A5 real World checklist states that Landing grad CAN be extended in the water below 10 knots. It doesn’t happen in game, the gear handle goes down, but the gear won’t. It is a missing feature or a bug, but the point is that it is an amphibian plane after all, and just like the bush planes can land on fields, the A5 (and future FS seaplanes) should climb on ramps in some bespoke ports, or in some beaches. Landing gear down in water. It is a an amphibian plane. Fix ASAP.
Water effects. Nothing more to say. They are missing. Obviously. Take you time, but do it right.
Icon A5 Garmin GPS split screen functionality. The real A5 can show an aviation instruments duplicate on the GPS. For Icon A5 this is a must, as you can have access to a full 360 HSI and real vertical speed indicator. Not particularly useful, but it would be nice to have fir those who want to use the A5 in its full capability.
(…and now the useless stuff)
Bigle purge simulation. The real icon A5 does take some water in and has a pump to purge water out of it. It is not hard to simulate, as time goes by, when in water and Stopped, the water gets in as dictated by timer, the bigle light is turned on, player needs to flick the switch to purge it and take off only when light is off.
Open canopy functionality. Last on the list, probably will never happen, but it isn’t too hard to do, and would make so ■■■■ cool screenshots.
That’s it guys.
That is all it is missing.
If FS gets those not only will the Icon A5 be feature complete but it will be the Icon A5 simulator to date.
And (as in ALL FS 2020 Garmin GPS systems), there is the mistake of having:
->The “nearest” menu having the waypoint info data and…
->The “waypoint info“ menu has the nearest Airport data.
You get the idea, the 2 menus have switched content. But that is an overall FS2020 Garmin oopsie rather than an Icon A5 related thing.
