Alright, one more try.

     if (GamePlay.gpAirGroups(1) != null && GamePlay.gpAirGroups(2) != null)
     {
         if (Time.tickCounter() % 9000 == 0)
         {
             int totalAircraft = GamePlay.gpAirGroups(1).Length + GamePlay.gpAirGroups(2).Length;
             if(GamePlay.gpPlayer().Length > 0)
             {
                     GamePlay.gpLogServer(new Player[] { GamePlay.gpPlayer() }, totalAircraft.ToString(), null);
              }
              if(GamePlay.gpRemotePlayers().Length > 0)
              {
                     GamePlay.gpLogServer(GamePlay.gpRemotePlayers(), totalAircraft.ToString(), null);
               }
         }
     }

If you're not using a dedicated server, you can get in an aircraft on the server and this should work.

     if (GamePlay.gpAirGroups(1) != null && GamePlay.gpAirGroups(2) != null)
     {
         if (Time.tickCounter() % 9000 == 0)
         {
             int totalAircraft = GamePlay.gpAirGroups(1).Length + GamePlay.gpAirGroups(2).Length;
             if(GamePlay.gpPlayer() != null)
             {
                     GamePlay.gpLogServer(new Player[] { GamePlay.gpPlayer() }, totalAircraft.ToString(), null);
              }
         }
     }
