Hmm...probabilities. The probability of me having an engine failure in my EC135 during a flight are extremely remote(has there ever been one?). The probability of me having one during the few minutes during take off and landing are even less. The probability of me having one during the few seconds it takes to accelerate to single engine fly away speed during take off are infinitesimal.
However, I'm still required to fly the Cat A/Class 1 profiles.
As the probabilities are so small, need I bother?
