0.5.0-alpha5

Create and edit SID/STAR procedure geometry with map previews, chart and TAS/bank calculators, context-aware tools, and safe source editing.

Added

• Radius/radial arcs, endpoint arcs, holding patterns and three procedure-turn layouts directly in SID/STAR source.
• Chart-constrained base-turn calculator with separate VOR/DME stations and explicit station alignment.
• TAS/bank calculator for turn radius, rate, duration and length, with radius transfer into drawing controls.
• Map picking and snapping, segmented map/source previews, and guarded Apply with Save, Undo and Redo.
• Exact source/map row selection; insert, move, drag, delete, reverse and resample coordinates.
• Context-aware right-click menus for point, segment and range editing, drawing, comparisons and calculators.
• Coordinate clipboard normalization, explicit named-point conversion, and up to six read-only procedure reference pins.
• Configurable procedure geometry warnings with precise Problems/source/map navigation.

Fixed

• Preserve header-only named points when a generated hold or turn starts there, without a duplicate first segment.
• Respect <br> starts of separate SID/STAR paths and blank formatting lines; preserve boundaries through editing, previews, selection and geometry warnings.

Known limitations

• Output is coordinate-based display geometry. ARINC leg semantics, atmospheric IAS-to-TAS conversion, wind and flight-dynamics simulation are outside this release.
• Chart radial inputs use the entered VOR station alignment; local magnetic variation is separate for other drawing tools.
• Airport-area and density warnings are adjustable advisory checks.
• After reopening, generated shapes are edited through their source coordinates rather than stored parametric metadata.
