Boeing has done design work to reduce tail strikes, including implementing an improved elevator feel system in some airplanes. For example, the 747-100/-200/-300 has varied feel (column forces) throughout the center of gravity (CG) and weight envelope. The newer 747-400’s elevator feel system design provides a constant feel elevator pressure, which has reduced the potential of varied feel pressure on the yoke contributing to a tail strike. The 747-400 has a lower rate of tail strikes than the 747-100/-200/-300.
To me, this is a bit counterintuitive, since I would have guessed that a varied elevator feel would have made tailstrikes less, not more, likely. This would be so because varied feel might allow the pilot to sense when his actions are about to cause a tailstrike. But the article says differently. Could someone please explain why?
Thank you in advance.
