G iv captain experiences a TCAS RA at low altitude departing mry requiring an aggressive pitch over ...

Narrative:

We were cleared for takeoff on runway 28L at mry; runway heading to 7;000 ft. After takeoff the tower advised us of traffic at 12 to 1 o'clock and stated traffic had us in sight. PNF stated negative contact. Neither of us could see the traffic. Tower switched us to norcal departure. At approximately 3;000 ft a yellow TCAS target appeared to the right showing +1;000 and then we had an immediate 'descend' RA with the green box showing a steep pitch down. I pitched the aircraft forward putting the command bars in the green box. The RA cleared and we immediately had a secondary and steeper 'descend' RA which required a very steep descent and negative g to comply with the RA. As soon as the RA cleared we had a taws 'terrain....pull up' command. I immediately made a smooth pitch up recovering at approximately 1;700 ft; advised ATC of the RA and climbed to 7;000 ft with no further conflict. The pitch over to comply with the RA was dramatic and required an aggressive and deliberate response which frightened the passengers. The TCAS worked as it should and must be complied with; but it is unnerving pitching over at a low altitude. It would be helpful to practice low altitude/descend RA's during recurrent training.
