You can add this code to a script:

using System;
using System.Collections.Generic;
using maddox.game;
using maddox.game.world;


public class Mission : AMission
{

    private void setMainMenu(Player player)
    {
        GamePlay.gpSetOrderMissionMenu(player, false, 0, new string[] { "Start Airgroup Engines" }, new bool[] { true });
    }

    public override void OnOrderMissionMenuSelected(Player player, int ID, int menuItemIndex)
    {
        base.OnOrderMissionMenuSelected(player, ID, menuItemIndex);

        if (ID == 0) // main menu
        {
            if (menuItemIndex == 1)  // Start Airgroup Engines
            {
                GamePlay.gpLogServer(null, "Start Engines", null); // Controlmessage
                GamePlay.gpPlayer().Place().Group().Idle = false;
            }
        }
    }


    public override void Inited()
    {
        setMainMenu(GamePlay.gpPlayer());
    }
    
    
    public override void OnBattleStarted()
    {
        base.OnBattleStarted();

        MissionNumberListener = -1;

        GamePlay.gpPlayer().Place().Group().Idle = true;
    }
}

With this you can give a "Start Airgroup Engines" - Command via the communication menu. 4.Mission -> 1. Start Airgroup Engines.

Little Explanation with
GamePlay.gpPlayer().Place().Group().Idle you can set the player Airgroup to Idle (true) or active (false).
So at the beginning i set the player airgroup to idle (true).
And add a entry to the mission menu, so the player can activate the airgroup manually.

This Script works in singleplayer and with actual beta (needs GamePlay.gpSetOrderMissionMenu and OnOrderMissionMenuSelected(..) ).
