Methinks you might be in line for a potential fall from grace at some stage ...
(a) with the dynamics of the engine failure situation, any time you are at or near to book Vmca for the speed schedule is a time to be wary of control problems. Any fool can handle the routine V1 failure situation with ease ... a bit more in the way of holding the tiger by the tail if the failure occurs half way through rotate ... especially if the weight is around minimum values. When, do you ask ? .. short range ferry comes to mind ..
(b) light weight takeoff (or missed approach) potentially sets you up for a Vmca encounter - certainly applies to the earlier 737.
(c) whether takeoff or missed approach, the dragon is awaiting to catch you at low weights and high thrust. The concern is thrust setting albeit that there may be slight variations to Vmca with configuration.
(d) the line pilot is at risk of succumbing to complacency as just about all the takeoffs experienced (and trained for in the sim) are at higher weights.
(e) Basically, you can firewall anytime you want and there is no chance to loose stability.
This is one of the most alarming statements I have read in a long while.
Be very wary of the dynamics if you choose to shove the lever up to the stop.
I can recall a turboprop fatal I had some investigation involvement in many years ago .. it is highly likely this is exactly what the crew did .. with quite undesirable consequences ... yaw, roll, cartwheel, burn, die. Very fortunate that the restaurant a few metres further past the ditch the aircraft ended up in didn't get involved as it was lunchtime .. the death list may well have been very much higher than it was.
(f) When we go around, we fly even lower speeds compare to the TO speeds, but then we don't really worry about the Vmca.
You may not .. and for normal weights the statement is reasonable .. however, very light weight and it might be a quite different animal to control ..
(g) and no directional control difficulties are encountered
At minimum weights, the dynamics might just overwhelm your ability to achieve this unless you advance the lever quite gently.
