Pixhawk motor throttels up ONLY in manual mode

Ok, So I got the latest firmware installed, radio is calibrated, and FC is arming. USing three flight modes- FBWA, Auto, and Manual. Servos are working in all flight modes but I can only throttle motor up in manual mode but not FBWA? Thanks in advance!

In flight or on the ground?

On the ground, it has not been in the air yet.
