When I am flying the 777-300 ER at 60% load, I often find it difficult to maintain a VS of around 600-700 fpm at an approach speed of 145-155 knots. The plane seems eager to drop (with VS of around 1000+ fpm). I need to maintain the speed around 160 kts to keep the nose level and VS < 900 fpm. What could be the issue and is the approach speed of 160 kts realistic? This doesn’t seem to happen with the A-330 or other aircraft, where I can land with much lower approach speeds at same load.
Thanks for your help!
