Hello all,I use the PSS concorde, and I follow this procedure. (from takeoff)Reheat on, full throttle. At approx 190kts, nose up to approx 18 degrees.At 500' RA or 01:11 on the timer, reheats off, nose down to 250kts and throttle back, maintain 250kts with the pitch, Vis/0.at 4000' on the QNH, Visor up, and pitch down to around 8-10 degrees. When reaching FL100, set speed to 390kts and INS (GPS hold) on. Then I let the aircraft climb up to FL280.At FL280, I wait until coastline at around 400kts (apprx 0.95M) When I reach coastline, I turn off the A/T, put full throttle on, then activate reheat again and engage max climb.The aircraft sits there at around 100f/m, and won't climb. I have a gross weight of about 150,000Kg. I remember one time it actually worked and I got up to FL500 just over Ireland (before I found a load of real concorde Fpls) but I can't remember what I did.
