I really enjoyed my time in the Gulfstream 2. What a sweet, grand, overpowered monster of an airplane.
Operationally, we usually planned our takeoffs taking advantage of this by reducing our takeoff thrust, pulling power back at approx 400 agl in the climb. It was still pretty loud.
I remember fondly my last takeoff in the jet, though. Long runway, short leg to fly. I knew it'd be the last time I ever flew one of these sweet smokers. So I briefed my copilot that it would be a full power takeoff with no power reduction at 400 feet. He loved the idea, too, because he was going to be transitioning to the G-4 in a couple of flights. So we just set the brakes, felt the wheels practically skipping across the pavement as we set max takeoff power, then let her go. The acceleration was typically exhilerating. The noise. The smoke. The fuel flow!
After liftoff, we just cleaned her up and let her go. Cleared almost immediately to FL430, we were there 14.5 minutes later. The flight only lasted 1.1 hours. What a sweet ride.
Cheers,
