I'm not a particular fan of my neighbor. Children of the Xbox have a tendency to play it at all times of the night, and his yelling at children on Call of Duty in the middle of the night was not conducive to me sleeping. This was further compounded by the fact that I had to report for duty on the flight deck of an aircraft in a few hours. I lay there, reviewing the V speeds of the CRJ in my head. The next thing I remember is my phone blaring stating its time for me to go to work. I have a short ugly rotation to Tucson before ending my day with a round trip to Kansas City. I find myself back in the briefing room around lunchtime with a sandwich as I peruse our flight planning data for the day with our captain.We'll be operating US Airways Express 2920, on Niner-One-Niner Fox Juliet, a CRJ-900, which is actually flown by Mesa Airlines, my slightly indignant employer. We'll be pulling 79 passengers halfway across the United States, and looking at around a two and a half hour flight. We'll be uploading another hour and a half of fuel on board, taking us slightly over MTOW, but we'll also be looking at a bit of a wait on the ground as we'll be departing in the 1 o'clock bank of other US Airways flights, compounded by Southwest's steady roll of departures. This will be my segment as PF, as the captain flew the previously leg in from TUS. With our flightplan hashed out, our weight and balance calculated, and a review of the weather, the captain and I make our way along to Bravo 22 where our aircraft is sitting.We slide our way past security into the mostly empty concourse. The airlines Express flights are mostly out flying now, so we'll be one of the few RJ's sitting around the terminal. Since they couldn't be bothered to hook the ramp up to let us on from the jetway, we have to walk down the stairs to walk up the stairs, one of my little annoyances. We set about doing a few of the preflight checklists in the airplane, pulling power from the GPU to provide us the necessary power to light the instruments up. Our captain enters the route into the FMC while I pop out and do the visual of the aircraft. Apart from being a bit on the dirty side, our aircraft looks airworthy. I get back to the cockpit and finish my preparations for an on-time departure.I put in the ATIS frequency, and par our briefing, the departure from PHX is looking clean. There is a light breeze from the south, and we'll be doing a runway 8 departure which equates to a short taxi distance. The captain calls clearance delivery and we get our departure details. We'll be flying the RIMMM 1 departure, our initial fix being the RIMMM intersection, then turning right 90 degrees to intersect SMALL, before another 90 degrees to run us parallel to the our departure runway before taking advantage of the RNAV to transition the St. John VOR at 12,000 feet before picking our way through a collection of air routes to point us towards MCI. With the door closed, we dial up ground for permission to push, 20 seconds ahead of our scheduled departure.With the nose facing our taxi out of the power alley, the steering pin removed, and the salute off to the dispatcher, I call for the APU off and then number 2 engine start. The aircraft systems transition from the APU to the batteries to the generators, and we're ready to taxi. We have a short taxi in distance, but about 8 other company aircraft heading to the runway in addition to a few Southwest 737's, a Frontier A319, and a Continental 739.I smoothly advanced the throttle quadrant to get the aircraft rolling and enter the queue of airplanes waiting for their turn to "carpe via". Flaps down to the first notch. I dial in my desired autopilot entries, and chose our thrust for departure, settling for a derated takeoff (as basically all CRJ takeoffs are) of 88 percent of the capabilities of our engines. We slowly work our way up to the front, my irritation in my deprived state of sleep inflating, and finally get the position and hold call as a company A320 rumbles down the runway. We've just slipped under MTOW of 84,500 pounds while waiting in line.The runway is mine. I throttle the engines up and watch the N2 and vibrations stabilize, and then hit the TOGA button and the aircraft accelerates to the desired thrust configuration set by the computer. The airspeed comes alive and it becomes more of a challenge to hold the centerline. Our VR is 144 KIAS. I pull back on the stick and launch into the sky.The gear goes up and the aircraft throttles back, still increasing the airspeed but travelling at a shallower pitch. I would post the rest of the flight, but apparently I can't even add additional photos in other posts because it just adds them to the first reply.
