thing:
I'm currently in AZ. Many airports around here are already above 6000', and the hot summer temperature even at altitude results in a "density altitude differential" (i.e., density altitude - pressure altitude) of 2500-3000' every day.
For instance, Flagstaff (KFLG) is on a high plain at elevation 7014'. In the late mornings and afternoons density altitude approaches 10.000' nowadays. The climbout is over forests and in some sectors slightly rising.
Much more critical however are some airports in the AZ mountains, where you have to climb out over hostile, sometimes rising terrain, and out of a valley (meaning also no radio or radar coverage, of course).
I often had climb rates of about 2-300 fpm. Even shallow turns to clear terrain (or slight downdrafts) can annihilate the climbing and cause some nervosity until the VSI needle goes North again.
That's why I want to max out the climbout right from rotation. To minimize excitement.
