Air Start? Lead computing gunsight?
Where can I go to read about these features?
Great thread by the way.
All disabled in the MAs - but in the DA for example, look on the map for a symbol that looks like a 3x3 box-grid on the map somewhere with a field number listed next to it, one of the boxes on the 3x3 grid will be highlighted to indicate that using that given runway at that given field will start you in the air "here".... this will do as an example -
Lets look at the air spawn in sector 3,18 - note it has a 3x3 grid with listing its associated field as A-60. So, to utilise it you go to the tower at A60, select your plane and loadout from the hangar, then select the highlighted grid/runway direction to launch on (in our example South), and ta-da. Some maps list next to the airspawn symbol what altitude it will spawn you at, but given they are usualy utilised for scenarios with high-altitude bombers and escort I find they average ~20k.
