The indicated air speed of an aircraft is the same for take off and landings regardless of the elevation. This would result in a higher ground speed and longer take off and landing rolls at high elevations.
Yep - the big problem is adjusting your visual perception to account for the change, esp. when you are really familiar with the aircraft. I flew a fairly highly loaded little sport .15 canard around Colorado Springs at 6100 feet, and while it flew fine, hand launches were notably more of a challenge (and they were a pain at low elevation) and landings were pretty hot compared to my normal 700 feet ASL.
What you have at 7600 feet is an aircraft with 11.36/14.00* = 18.9% less horsepower that at 1400 feet, that needs to fly at a ground speed of 18.9% more to behave the same way.
