Ok everyone, I agree with the whole 250/0.70 whichever is less in the climb. However take a look at our FOQA parameters:
The FOQA Monitoring Team looks at a variety of events such as the following:
• Excessive Taxi Thrust (>41% N1 Dual Engine / >51% N1 Single Engine)
• Climb Speeds < 250 Knots above 10,000 feet and < Mach .70 above FL280• High Descent Rates (> -5000 feet per minute at all altitudes / > -3000 feet per minute during approach)
• Flap Overspeeds
• Flaps < 45 degrees / Thrust Reversers not armed / Gear not down by 1000 feet on approach
• Vref deviation at threshold / High or Low landing speeds
• Hard Landings (> 1.45G)
• Excessive Reverse Thrust (>30% N1 below 60 knots for > 8 seconds)
What is up with that?

One thing we all need to understand here is we are using this "transition" point in a multitude of ways. Technically in the US we use FL180 to transition to 29.92". I believe there are many other parts of the world where the trans point is different and hence the ability to change the transition point easily within the FMS. Mach transition is different per airplane and per environment (temp). FL316 trans to half bank and Mach is ICAO I believe to deal with both the Meters and the understood ICAO point at which everyone will be reporting in Mach and FL. I have not studied nor flown international (beyond Canada) so I may be wrong, but that is what I understood when I looked it up in initial.
