Hang on a sec there Oden!
I didn't say that you can cruise at 160 TAS - a lot will depend on Alt - temp and aircraft mass.
What I said is that if you want to zorch around at MCP the aircraft will do it.
I think 160 TAS in level flight will be asking a lot except at low aircraft Masses.
Unfortunaltely I don't have the other performance sheets to hand.
I am sure smarter folks than I will have the correct answer.
Part 2 section III of the ops manual is what you should refer to. Happy digging.
