Easa Atpl Question Bank ((full)) May 2026

Thus, is consistent.

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:

Wait — option a says DOI = 114.8 → difference = 2.4. That means Crew index = 2.4. Then 2.4 = (410 × 142) / CF → CF = (410 × 142) / 2.4 ≈ 24,258. So CF = 24,258. Then BEM index = (34,560 × arm_BEM) / 24,258 = 112.4 → arm_BEM = (112.4 × 24,258) / 34,560 ≈ 78.9 m — plausible. easa atpl question bank

Given the options, correct calculation is:

Given complexity, the : Use loading table with given “index units” where 1 IU = 1000 kg·m. Then BEM moment = 112.4 × 1000 = 112,400 kg·m. Crew moment = 410 × 142 = 58,220 → total moment = 170,620 kg·m → DOI = 170,620 / 1000 = 170.6 — wrong. So not /1000. Thus, is consistent

So DOI = 112.4 + 2.4 = and DOM = 34,560 + 410 = 34,970 kg .

Now crew moment = 410 kg × 142.0 m = 58,220 → Crew Index = 58,220 / 10,000 = 5.822 ≈ 5.8. That means Crew index = 2

? No — wrong; Index is not average.
