Hi, Our application needs to build a network of taxiways at the airport where a pilot is currently located. As they taxi, the application needs to keep in mind the following points: * Announce with a screen reader such as NVDA, the current taxiway as the pilot moves onto it. * Keep track of the pilot's movements along the taxiways, then announce the new taxiway in front of them. * Provide directional guidance on the upcoming taxiway such as 'taxiway alpha to the left and right.', or 'taxiway bravo 1 O' clock to the right.'. * Announce to the pilot when they have strayed off of the taxiway such as veering into the grass. * Announce runways as they appear as intersections to the current taxiway in the event the pilot doesn't have RAS professional installed. * Automatically announce the distance in feet to the next intersection when they are 500 feet or less from that intersection. I know the .net library has a taxiways database. However, I am not clear on how to start implementing these features. If anyone has any starter points to try, it would be appreciated. Announcing with speech isn't a problem, as long as I can get the taxiway network built and understand how it works.

You can ignore this post. I figured it out. I forgot to put PMDG777.RefreshData() in our main timer event. Everything works now.

Hi, I have a class called SingleStateToggle that has properties for offset, name (string that is self-assigned), AvaliableStates (0=off, 1=on, etc...), CurrentState (KeyValue pair of byte/string), and a few additional properties. When creating an instance of SingleStateToggle, the offset I assign doesn't change values when trying to find the KeyValue<byte, string> pair for the CurrentState. Here is some code to demonstrate my problem: SingleStateToggle: using FSUIPC; using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace tfm.PMDG.PanelObjects { class SingleStateToggle: PanelObject { private Offset<byte> _offset; private PanelObjectType _type = PanelObjectType.SingleState; private Dictionary<byte, string> _availableStates = null; private KeyValuePair<byte, string> _currentState; public Dictionary<byte, string> AvailableStates { get => _availableStates; set => _availableStates = value; } public KeyValuePair<byte, string> CurrentState { // Try to retreive the KeyValue pair that matches offset.value. get { KeyValuePair<byte, string> item = new KeyValuePair<byte, string>(); foreach (KeyValuePair<byte, string> pair in this._availableStates) { if (This._offset.Value == pair.Key) { item = pair; break; } } return item; } // End Get } // End CurrentState. public override PanelObjectType Type => this._type; public Offset<byte> Offset { get => _offset; set => _offset = value; } public override string ToString() { return $"{this.Name}: {this.CurrentState.Value}"; } // End ToString. } // End SingleStateToggle. }// End namespace. In a class for the PMDG 777, I have the following code: using tfm.PMDG; using tfm.PMDG.PanelObjects; using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace tfm { static class PMDG777 { public static PanelObject[] PanelControls { get => new PanelObject[] { new SingleStateToggle {Offset = Aircraft.pmdg777.BRAKES_ParkingBrakeLeverOn, Name = "Parking break", Verbosity = AircraftVerbosity.Low, PanelName = "Forward", PanelSection = "CDU", AvailableStates = new Dictionary<byte, string> { { 1, "on" }, { 0, "off" }, }, }, }; } } // End PMDG777 class. } // End namespace. After putting a breakpoint on SingleStateToggle.CurrentState, nothing happens except the foreach loop runs multiple times before dceiding that 0 is always the _offset.Value value. We do have the timer that runs the process method for all the offsets. Do you have any ideas why _offset.Value never changes?

Hi, This will prove very useful. Thanks for the hard work. I will try it out a little later today.

Hi, I would certainly leave those options available. Our current mapping system uses a class to represent a coordinate pare, so the order doesn't really matter. Here is some sample code to demonstrate the GeoDataLocation class: var request = new GetBoundaryRequest() { EntityType = BoundaryEntityType.PopulatedPlace, LevelOfDetail = 3, GetAllPolygons = true, GetEntityMetadata = true, Coordinate = new GeodataLocation(43.7001, -79.4163), }; // End request. var response = await GeodataManager.GetBoundary(request, "api key goes here"); MessageBox.Show(response[0].Name.EntityName + response[0].EntityMetadata.PopulationClass).ToString(); foreach (GeodataPolygon location in response[0].GetPolygons()) { foreach(GeodataLocation point in location.ExteriorRing) { latLongListBox.Items.Add($"{point.Latitude}, {point.Longitude}"); } } }

Hi, The typical representation of a coordinate pair is lat, long as a decimal or double. Keeping it in this format will make things easier. Let me know if there is anything else you need before release.

Hi, I am the one working on this part of the project. To make clear, the lat/long of the plane is the only known constant. I will not know when, or where the points on the outline will appear in relation to the airplane. So, if I am flying heading 0, and want to take a "look" at heading 5, I will not know what points will appear at the given heading. This does solve 90% of our problems. The only thing left to figure out is the names of major bodies of water, given a GPS lat/long pair. At this point, Bing maps doesn't do this.
