Golden rule: never fly a light twin at MTOW.
What aircraft was that on?
The Twin Comanche for example will climb at 260ft/m at MTOW (Sea Level and ISA), reducing to 100ft/m by 4000ft density altitude on one engine. But at low weight it will climb at almost 500ft/m...which could be the difference between crashing...and not.
I've come to the conclusion that if you want to always be safe and have a *guarantee* of not crashing beyond the runway due to an engine failure up to the point of Vyse when one can safely climb away you need at least 1300m of runway.
