Easa Atpl Question Bank [repack] May 2026

Actually: only if index units are moment/constant and the constant is the same. Let’s test option a: DOI 114.8.

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.

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

Thus, is consistent.

Given BEM index = 112.4 at 34,560 kg. Crew: Mass 410 kg, arm 142.0. To add index, use: Added Index = (Mass × Arm) / (Reference constant) ? Wait — in EASA questions, often the index is a simple moment / 1000 or moment / 100,000 . We must deduce the Index Unit (IU).

Index formula typically: , but in this question bank, they provide index directly for BEM and arm values for others. We must compute additional moment index from crew:

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:
