Unpack net_ctrl variable packet received from
FlightGear
Aerospace Blockset / Animation / Flight Simulator Interfaces
The Unpack net_ctrl Packet from FlightGear block unpacks
net_ctrl variable packets received from FlightGear via the
Receive net_ctrl Packet from FlightGear block, and makes them
available for the Simulink® environment.
The Aerospace Blockset™ product supports FlightGear versions starting from v2.6. If you are using a FlightGear version older than 2.6, the model displays a notification from the Simulink Upgrade Advisor. Consider using the Upgrade Advisor to upgrade your FlightGear version. For more information, see Supported FlightGear Versions.

1. Если смысл перевода понятен, то лучше оставьте как есть и не придирайтесь к словам, синонимам и тому подобному. О вкусах не спорим.
2. Не дополняйте перевод комментариями “от себя”. В исправлении не должно появляться дополнительных смыслов и комментариев, отсутствующих в оригинале. Такие правки не получится интегрировать в алгоритме автоматического перевода.
3. Сохраняйте структуру оригинального текста - например, не разбивайте одно предложение на два.
4. Не имеет смысла однотипное исправление перевода какого-то термина во всех предложениях. Исправляйте только в одном месте. Когда Вашу правку одобрят, это исправление будет алгоритмически распространено и на другие части документации.
5. По иным вопросам, например если надо исправить заблокированное для перевода слово, обратитесь к редакторам через форму технической поддержки.
