Task List

Short term plans

General areas I'm working on, or planning to work on

Investigate if caching cartesian positions on FGPositioned is a good space versus time tradeoff
Remove the _list classes as they become obsolete.
- Many of the list classes are gone now - the major remaining piece is the nav_list, which is used to support frequency-based lookups of radio navaids.

Extend the GPS code to support more flight-plan functions and en-route information
- Climb/descent computations, based on some aircraft performance data
Add proper support for special leg types, ideally equivalent to ARINC-424 path-terminators. This implies support for DME arc, heading to fix, heading until crossing radial, holding pattern and assorted other special leg behaviours.
Create a new generic 3D instrument for the KLN89b, using Nasal and the updated GPS code
Create a generic 3D instrument modelling a Delco Carousel INS, using the GPS as the backend
Investigate creating a special camera/view mode and input context so a GPS, FMS or other 3D instrument can occupy most of the screen, and intercept key presses. GUI dialogs must solve the keyboard input issue already. Imagining that a click on the instrument animates the camera to a 'face on' view, and click outside the instrument returns to the previous view point.
Add GPS precision approach support
- Define an on-disk format for defining approaches. This will likely be similar to the navdata.org / PIC-767 XML format
- Add approach and missed-approach modes to the GPS code
Extend the route manager to allow basic flight-planning
- Generate a route using a search: VOR-VOR, airways or GPS direct.
- Thomas Forster has generic routing code for this
Allow performance data to be specific per-aircraft
- Initially, basic information such as cruise speed, best climb rates, and so on
- Weight/balance tables
- Vspeeds computations

Prototype a Nasal canvas API (similar to HTML5 canvas), but with support for retained primitives.
Get primitives rendering into the existing scene
Write a nasal driver, with appropriate C++ glue, to query waypoints

Add realistic Mach computation to the airspeed indicator, so it can be used as Mach-meter too, and avoid panels reading /velocities/mach directly.
