V-ILS 


I've been using an AnywhereMap ATC for a couple years and a Lowrance 600C before that.

Up until a year ago the ATC and other AWM software had a very neat feature called a virtual glide slope. A year ago the company, in an effort to make this feature more useable or attractive (who knows why. . .), actually ruined it. Before, it was a conventional needle-against-a-scale display that was very useful for giving descent guidance to any runway in the database. Terrain clearance was possible through configuring the GS with a 5 or 6 degree angle which would put the FAF at or neat the boundry of the traffic area. Turning terrain depiction on for the approach was also helpful in this regard. I used to practice with it on just about every approach so I am one of the AWM customers that actually used this feature. Then, in a misguided attempt to make the glideslope more attractive (I guess . . . I actually have no idea why the company did such a stupid thing as to ruin this feature), they changed the display from a needle/scale display to a block display that changes color as you go up or down. I hated the change since it is totally unintuitive but worse than that, it doesn't work. I've tried to use it and it's impossible. Flying an ILS requires small adjustments in response to small trending motions of the indicator. This new disaster only registers change in block-sized increments and is impossible to use. But it's colorful and has a larger display than the previous one and somebody at AWM - some non-instrument rated programmer who has no idea what he's done - thought this new thing would be more impressive. I suppose it is, until you try and use it. Complaints on the AWM forums about the V-ILS change have been numerous, but AWM stopped listening to its customers a long time ago.

Anyway, this was a really interesting and useful feature that is no longer interesting or useful.

How hard would it be to incorporate a V-ILS into the iFly 700? It already has approach plates so in an emergency, a person could arrive at the published FAF and just invoke the V-ILS at that point, following the needle down to the numbers.

As it stands, the AV8OR Ace is the only portable GPS that has a workable V-ILS. That thing costs almost $2K.

At some point I will be abandoning the very quirky ATC and moving to another GPS. The iFly 700 is at the top of my list.

Please consider incorporating a V-ILS into the iFly software. I would make the switch from the ATC to the iFly tomorrow if it had such a feature.

Thanks,

Mike

P.S. I've attached a photo of the ATC screen in night mode showing the old V-ILS on the left side of the screen.

Well, I see response has not exactly been overwhelming to my suggestion of incorporating a V-ILS. I suspect it is because it is a feature only a few people find useful. That's the way it is over on the AnywhereMap forums. Vertical navigation features are only of interest to instrument pilots and they are using certified equipment for their approaches.

The nice thing about the V-ILS is that if those instrument pilots lose all their electrics while in the clouds, the V-ILS can be configured for the nearest appropriate airport and will get you safely down to the runway. If the terrain database were integrated (it isn't on the AWM version) it would do so safely. If not, one needs to have knowledge of the terrain below or a chart. My instrument instructors many years ago insisted that I was not really prepared for instrument flight unless I had WAC's or Sectionals of the route of flight, in addition to the instrument charts. For this scenario to work with the iFly it would need supplementary power so I guess the best way to do it is to run the iFly from a battery pack which is connected to the aircraft electrical system through a charger.

Anyway Walter, even though no one else has commented on the V-ILS feature, if you run out of things to improve please keep it on your list. I'm sure your rendering of the idea would be as good or better than the way the ACE does it and there's no question it would be better than the "new" implementation of AWM's - which is currently unusable.

Congratulations on such a fine product. In the pilot community that I'm familiar with it is building a very good reputation, both for it's features and price but also for great customer service.

Some good news: The next iFly software update includes some vertical navigation features. It's not exactly as you describe here, but could probably be made to work like this if desired. We have 2 new instruments: "Vertical Speed", and "Vertical Speed to Target". By default your target altitude is defined as the pattern altitude for your destination airport, 1 mile out. But all this can be overridden, and you can also create ad-hoc target elevations. So you could theoretically create your flight plan all the way "to the numbers" by creating a waypoint at touchdown point and specifying the airport elevation.

Hope this helps,
Walter

That's amazing. Keep it up and the G-1000 won't have anything on the iFly.

It will be interesting to see how you display the vertical path. I would hope it's a conventional needle-against-a-scale indication. Sounds like the slope angle could be adjusted by creating an intermediate waypoint - say the boundry of the ATA. Very interesting what you have planned!

Thanks for the quick response.

We won't be displaying it graphically yet, but a set of simulated analog instruments is on the list. For now we will give you a digitial readout of your current vertical speed (averaged over a few seconds to smooth out the bumps), and a required vertical speed to reach your target. You just need to try keep those numbers close.
