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:
Crew index = (410 × 142) / 1000 = 58.22 → but that’s too large. easa atpl question bank
First, convert BEM and crew items into moment index. Therefore, this question uses a
Total DOI = BEM index + Crew Index = 112.4 + 5.8 = ? That doesn’t match any option — contradiction. Total DOI = BEM index + Crew Index = 112
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.
a) 34,970 kg / 114.8 b) 34,970 kg / 115.2 c) 35,130 kg / 114.8 d) 35,130 kg / 115.2 Explanation: Step 1 – Calculate Dry Operating Mass (DOM) DOM = BEM + Crew & Crew Baggage + (other fixed operational items if any – here none except crew) DOM = 34,560 kg + 410 kg = 34,970 kg
Given the options, correct calculation is:
