[Question] why there's no line to first waypoint in a Plan? #308

Open pasniak opened 7 years ago

pasniak commented 7 years ago

After plan is activated. Is it bug or feature?

apps4av commented 7 years ago

Its not a bug. Where you start from is not a way point that distinguishes it. You can start from anywhere, any airport.

CDI does not work then on this "direct to the first plan waypoint" leg? I simulated few plans and CDI indications do not make much sense to me...

avcomware commented 7 years ago

Be more specific on the Plan, Location, procedure how you tested that. I can test in a sim.

I started with a simple case of Destination.

I started the GPS sim at 42.14 -71.22 hdg 45 spd 290 and Fly To Destination. cdi-full-left-2017-07-18-064052

Then I selected destination BOS (no plan): CDI-full-left-2017-07-18-064052.zip

CDI white triangle is pegged to left which is I guess because I am very close to the dest. (BTW: It is also unclear from GUI or Help what "one tick" is and whether it is in degrees or miles to distinguish from CDI in top map display which must be in miles - is it?)

"The CDI is operational when you have a destination set. The needle indicator at the bottom will move left/right of center based upon how off course your location you are. If you deviate more than one tick left or right then the indicator changes color - RED if you are left of course, GREEN if you are right. To correct, steer the aircraft in the direction of the arrow to bring it back to center"

So I thought: my "wrong CDI" was due to simulated plane being very close to the plan destination.... but then I made the plane chase the destination in plan and CDI deflection looks somehow random... CDI-deflection-random-2017-07-18-075817.zip

Another thing that gets me confused is I looked at G1000 GPS CDI doc and it actually shows refers to deflection in miles (see G1000 Pilots Guide) for GPS source or degrees for VOR/LOC source.

Lastly, CDI is probably missing a color for "on track" deflection - as there is no need to indicate need to turn.

To summarize: maybe we should display some other color (gray?) when we are "on track", document or change GUI to say what ticks are (degrees)?

Hi. My procedure, typical for real life: I placed the acft at KSNA aiport. Long press on a GPS point and select D. The CDI was centered in Green color. As I was flying to the South the pointer changed to Color Red and the pointer shows needed right correction. As I continued on it performed as expected.

That said I think that the colors are not very intuitive / logical, when I compile my own version l select Green for Center, Red for Right and GRAY for left. For the VDI I use Blue High, Green center Red if you are low. I also make changes to the List to accept 500 lines, that are needed for detailed Checklists for students mainly and a few others.TV
