Hint :
Easy climb:
Hold [F4] while flying then press Y. Release both keys and your aircraft should be climbing without putting the nose up.

Tip: Flying the Concorde demands that you carefully monitor the aircraft's fuel distribution to ensure a proper center of gravity for supersonic flight. Keep the fuel panel window (Shift-4) permanently displayed over the regular instrument panel so you can quickly pump fuel reserves as needed to maintain the correct center of gravity.

Tip: Turning on the axis indicator from the View Options pull-down menu permits you to line up your final approaches with much greater precision. Having a small, red V in the middle of your windshield to denote the plane's centerline helps to make those touchdowns a little more accurate.
