No problem. Bear in mind these are differences for the 767-300, where the differences exist against the 752/762
With the longer fuselage, this must be lower than for the 752/762. Theoretically, about 2.5 degrees per second (where the 752/762 is 3 degrees per second).
The rotation rate is very important especially in the case of an engine failure since the minimum tail clearance is only 12 inches. This minimum clearance occurs in the 763 after lift-off.
Typically the nose-up attitude is about 1 degree lower on approach on the 763 than the 752/762, leading to a typical approach attitude of 1 to 3 degrees on the 763, rather than about 2 to 4 degrees.
It sounds a small difference but in my experience for normal landing weights the approach is noticeably flatter on the 763.
Flare Height is slightly higher on the 767 than on the 757 - 25 feet Radio Altitude rather than 20 feet. For normal pitch attitudes the main wheels on the 767 are 4 feet lower than on the 757.
As a general rule, there is less time between the automated "30 ft" call and the start of the flare. The time between the "30ft" call and the start of the flare on the 757 is suggested at 1 second, but one second is a long time in aviation so about 0.5 seconds after the call for the 763.
Remember also that the pitch attitude on completion of the flare (waiting for the a/c to settle onto the runway) is about 4 to 5 degrees nose-up, compared to 5 to 6 degrees on the 757.
For the 767-300, the readings on the flap gauge do not represent the true flap angle. They are used purely to achieve commonality with the Boeing 757.
On the 767, Flap 1 (for example) only extends the leading edge slats (no flap at all). Flap 15 is similar to Flap 20 on the Boeing 757 and Flap 30 is in reality at an angle of more than 30 degrees.
Airbus have got it right here IMO, give the flap configurations numbers (1, 2, 3, Full) since the 767-300 proves the point that the actual angle the flap is extended is not relevant.
Hope this proved of some interest.
