Switch between types of missiles Helicopters

Hello all
Recently, when using a helicopter, I do not need to activate or choose the type of missile that I will launch, whatever it is AGM or AAM , Now I have to choose them every time ,

how I can use two of them without choose them every time

Check in Options, Air battle setting, Automatic activation of aircraft weapon at mission start. If it is set to, YES, it will require you to select specific secondary weapon system to fire. You can set it to no, or you can set a keybind to exit selected weapon mode in your helicopter controls. Once you exit the weapon selection your normal keybinds for each individual weapon system will function.
