Narrative:

Very bad weather all day; finally an opportunity to take off arose; but we had to depart off runway 7 the briefing guide doesn't have any climb guidance on either of the sids off [runway] 7. We were on the climbout passing 10;000 feet; the airplane commanded a decrease in pitch to start accelerating to climb speed. This caused a caution terrain. We had visual contact with the terrain and continued our climb.runway 7 is hardly ever used; we need more information in the briefing guide and on the company jeppesen pages. Departing RWY7 there is no climb speed guidance. There should be a recommendation for a climb speed of left/D max (minimum drag speed) until 14;000 feet off that runway. We reach 10;000 feet very quickly and then the airplane goes into acceleration mode.
