Airport view and even more…

After several months of work, the most awaited feature is now here, the airport view !

This is a major update for both server and client and it will allow lot of new features in the future.

Airport view brings you a good view of what happens on taxiways and ground and make approach easier as you no longer need F10 view to manage airport.

Maps are updated (Caucasus and Persian Gulf) with better quality and accuracy. (WIP : others maps and layers will be updated)

Labels management is improved. You can choose how it will react when overlapping : see options/labels menu to customize it.

Dedicated install is now easier, no more Config/Options.lua to edit, check the documentation

LotAtc Advanced and Generator introduction

LotAtc Advanced

As promised, all LotAtc 1.x licenses will be compatible with LotAtc 2.x.

And now let me introduce you a new product dedicated to most advanced users : LotAtc Advanced.

Here are following new features :

  • Server admin commands, control DCS server from LotAtc Advanced client
  • Theme support
  • Coming in the future:
    • Datalink support with DCS
    • Add multiple SITAC view
    • IA control via MOOSE from LotAtc Advanced client
    • More server admin commands (load miz file, mission script interaction like triggers…)

At this time, some LotAtc Advanced features (theme, server admin command) are available to Standard users during beta phase.

Once released, LotAtc Standard and Advanced will keep the same install/executable files and Advanced features access will be enabled by the license.

LotAtc Standard and Advanced versions will always be compatible each other and will run with same LotAtc server without any restrictions. The goal is not to split LotAtc community but to offer advanced features. The development cost of these new features will be supported by advanced license price whereas standard ones will remain the same.

LotAtc Generator

LotAtc Generator is a server/generator to use LotAtc client/server without DCS, perfect for learning purposes, make your scenarios, save them in Tacview file for better debriefing, use full datalink support simulation… (it will be available with 2.0.0 final)

Using LotAtc Advanced you can create/edit/remove any contact in all coalitions.

Make a scenario simulating a BVR engagement between red and blue for controller students, then add dynamically whenever you want a liner that will travel so that learners must adapt!

LotAtc Generator can accept LotAtc Standard and Advanced versions without any DCS. It is perfectly adapted to learn GCI without the need of human pilots.

Price and availability

LotAtc Advanced is partially available: some features (theme and server admin) can be tested for free in standard version during beta phase

Generator is under development but functional, tracks can be edited with LotAtc Advanced (speed, altitude, heading…).

Price and full availability will be communicated in next weeks.

Existing licenses could be promoted to Advanced licenses.

Back on LotAtc 2.0.0-alpha1

I have updated network protocol communication on this version, it is not compatible with 1.x client/server.

This is an alpha version, meaning that :

  • It should be considered as unstable
  • There are bugs/regressions (let me know if you find them!)
  • Everything is WIP, not yet finished and could change in next versions, depending of your feedbacks
  • I need to finalize airport view (Iran on PG, Nevada…)

Thanks to all for your support and your help, special mention goes to Looney of 132nd for your symbols!

Next weeks will be focused on stabilizing this version. Efforts will also be put on:

  • Update website/documentation
  • Develop new features: generator, datalink…
  • Mac version for client (linux?)

Good to know

  • You can install over a 1.x install
  • Settings are no more in register and migrate on %appdata% directory, so 1.x settings will be ignored
  • For Persian Gulf, you will need to check visual maps download to get updated map and airports in installer

Rework of radar modelization

  • 2 modes:
    • Global: all available radars make the total radar coverage as in LotAtc 1.X
    • Monoradar (WIP): Each controller will have to choose the radar to use, it will get only contacts from this one (later coverage will be completed by datalink simulation)
  • Add RCS simulation: all items (planes, heliccopters, missiles…) will be computed and displayed if radar can see it using their RCS resolutaion and item own RCS
  • Add Radar resolution : if enabled, radar will not see items near each other, only one track could be made ( for example 3 aircrafts separated by 20m will be seen as only one contact)
  • Add spot/track management : radar will first see a spot with no data, then after a while (for example 6s, could be csutomized) if the spot is always there, a track will be made on it (and have data as speed, hedaing, symbol…)

All theses options can be enable/disable in profile lua file (see profile/custom.lua for more help).

Better support for dedicated server

  • Enable dedicated_mode in config lua
  • No more need to edit Config/Options.lua
  • Put your licenses in Saved Games//LotAtc Data/Licenses/ In config.lua, enable dedicated_mode, no more need to edit Config/options.lua, just install LotAtc mods now in dedicated saved games directory

Add more control to controllers login
Server admins can now:

  • Blacklist/Whitelist Ips (there is still some troubles with IP6 support)
  • Add specific username/password that will be authorized to connect with LotAtc
  • Enable/disable old login way by standard passwords (blue/red one)

When no controllers are connected, footprint of LotAtc server (CPU/RAM) have been reduced
