Andrew Birrell, King Air B200

On the flight back [from Germany], we had an initial climb rate in excess of 2,500 feet per minute. We departed from EDMS, field elevation of 1,051 feet, and climbed to FL280 in around 16 minutes, 30 seconds. It was an ISA day on the ground, and ISA – 2°C at FL280. We had a TAS of 293 knots, on a fuel burn of around 315 pph per side. Even [with] a headwind of over 60 knots at some stages, we still managed to complete the 600 nm flight in just under 2 hours 30 minutes, including the usual ATC vectoring around London. All in all, I am very impressed with the [upgrade]!
