Thank you for that information. Anything else than an fuel sensor/flow sensor is guess work anyway. It is just the way it is represented.

G1000 uses the fuel flow sensor - it doesn't guess!

Att: Runways, thanks for your input. I do not think I have anything else to add at the moment, I will try to do some more thinking about the matter.

Att: Tim, thank you for looking into this. If I am not completely wrong G1000 have a simulare feature. So I do not think this would be a negative thing to have in Skydemon. At least in planning mode. Anyway, let me say thank you for great support and software.

Att: ckurz7000, I agree with you on that, I always calculate the fuel consumption, and the value are quite steady.

First, fuel gauges are often not any more accurate than guesses anyway. And you could let the user enter his best estimate offering SD's guess as a default value.

At the moment, SkyDemon does not make any attempt to keep track of fuel used, since there isn't really any point, and it would be purely a guess based upon input "ideal" conditions too. I am reluctant to show any "range circles" based upon a number which SkyDemon is basically just guessing at. GlideSafe is different because even though it takes wind and terrain into account, there is no fuel equation.

If this post is a poll, I don't seem to be able to find a place where to cast my vote.

I vote for "Yes".

-- Chris.

Hello B2Spirit, Many thanks for the clarification. I actually didn't say No or Yes for this feature.

Hi, thank you for your reply.

Regarding the leaning question. In my aircraft profile, I have entred the fuel flow for best performance, and i know that my fuel flow is 8,8 gph. So I do not see your leaning problem, but then again the world is not perfcet. This would be an indication.

My initial idea to this feature was during planning a long trip. I wanted a way to see fast and easy my range was from my initial starting point. I wanted to know how many fuel stops I should plan for and so on.

If the range circle is useful for short trips with full fuel? I don't know. Maybe not with a large range. But then again, I tried to set up a poll, one answer for yes and one for no. Maybe your answer in this case is no, this may not be usefull for all. However this is a feature I would like to have and would find usefull.

There are features in Skydemon that I do not use or find useful, some of these features may be very useful for other users.

Edit: att Runway

I see your point. Maybe the range should only be drawn if it drops below a user selectable threshold which can be specified in the aircraft settings. Setting the threshold range to zero would effectively turn this feature off.

Another point to ponder is zoom level. There's no point drawing the range circle if it extends well past the map region currently displayed.

So, draw the range circle (it's not going to be a circle with wind present) only if endurance or range drops below a predetermined value and the map area currently displayed is larger than the computed range.

-- Chris.

OK, that is understood. The range is also varies according to leaning the fuel mixture (fuel flow) which can affect the amount of fuel used per hour.
