The MGB is built really really well and can take a hell of a load. If you get into a hole and need to get out of it the you may need a lot more that 114/114 and what a shame to DIE for the sake of your concern for your bosses wallet - and it may be insured anyway.

An interesting area for further deliberation is that when in 'Manual Mode' the logic of the Torque matching over-rides the actual Torque used so that with one engine at 112 and the other at 80 it will declare a TRANSMISSION OVERTORQUE on the CAS even though the total MGB Torque is less than the max 220. What happens if the TL is left on during Manual Mode? The answer is that it will artificially restrict your (legitimate) access to the full 220 by holding the high engine at 114.

This is a fine example of pilots 'reading between the lines' and using their intelligence to find a better solution ONLY they don't have all the facts.

Lovely story about the operator who was running a Dauphin C with the tricycle undercarriage. He wanted to modify it to the skids and bought the kit from Aerospatiale. Having completed the conversion he noted that the small tail wheel underneath the fenestron was still in place. 'Remove it' was the order, 'we need to save weight'. Well, they did and 10 hours later the fenestron disintegrated. With no tail wheel the vibes hit resonance at the fenestron and cause the total loss of the aircraft. Now the operator thought that Aerospatiale had forgotten to mention the tailwheel when they read the mod instructions but no, they just made the mistake of thinking that the operator WOULD DO AS HE WAS TOLD.

Remember - you dont know everything - and using your intelligence can get you into trouble if you don't have ALL the facts.
