? No — wrong; Index is not average.
Better approach: Use (common in EASA performance). Let’s verify: Moment_BEM = Index × 10,000 = 1,124,000. Then arm_BEM = Moment / Mass = 1,124,000 / 34,560 ≈ 32.5 m — plausible. Good. easa atpl question bank
Therefore, this question uses a . But in the real EASA bank, they predefine that the Dry Operating Index is directly given by loading table or simple addition of mass and index using: ? No — wrong
