[Kaktus]

First of all, not very proficient in the harrier but i did fire mavs before and now like couple of days later i can't.. 

 

1. master arms ON

2. Pick Mavs from STORE

3. double aft sensor select to get DMT running in TV ok..

4. find target, designate so DMT stays on target

5. sensor select FWD to select irvm mode for mavs

6. lock the target as i aproach ever so closer

7. nothing happens i can't fire the missiles..
