vnCorrNVU_VOR: "Virtual Navigator": Correct NVU orthodromic coordinates...
In thlytras/rfgfs: Flight planner and companion package for FlightGear

Description Usage Arguments

Through the FlightGear props (telnet) interface and on the Tu-154B, obtain radial and distance from a certain VOR/DME beacon, calculate the current orthodromic coordinates S and Z, and (optionally) tune them into the active NVU device.

1 2	vnCorrNVU_VOR(con, plan, leg, VOR, UShDB = 2, DME = UShDB, apply = TRUE, cols = c("fix", "fixLat", "fixLon", "ZPY"))

`con`	A socket connection object created with `fgfsConnect`
`plan`	A flight plan, as a data.frame. Plans created with `planRoute` are accepted as input. At a minimum, the data frame.should have three columns: waypoint names, orthodromic course headings (ZPY) and leg distances (S).
`leg`	The next (i.e. upcoming) leg of the flight plan. Specified as waypoint name.
`VOR`	The 3-letter identifier of the VOR beacon.
`UShDB`	Which of the two UShDB needles shows the current VOR radial? Either 1 or 2.
`DME`	Which DME radio to use? Either 1 or 2.
`apply`	Tune the active NVU device to the calculated orthodromic coordinates? If `FALSE`, these are returned without adjusting the NVU device.
`cols`	An optional vector of column names, if these are named differently in `plan`
