Hi john, well I did say "should be ok" And I didn't say "slam it to full power either"
If for what ever reason you find yourself getting short of the black stuff ( although it may be white !! ) I think it's better to add a bit of power if you are above the VMCG for that power setting than to run out of runway. Although one would hope that you recognised this problem a bit earlier and stopped.!!
I was trying to point out that on the 77W atleast 99% of the time you will be above the highest VMCG. The exception being very light weights ( 200 tonnes, which is empty ), To2 rating ( 20% derate ) and a contaminated runway causing a low V1
If you know your aircraft then this shouldn't cause too much headache.
