Flight Operations Manual Practice Test 2026 - Free Practice Questions and Study Guide

OpSpec C055 governs alternate weather minimums. It sets the weather criteria that must be met at an alternate airport for it to be usable in flight planning, and it can authorize using alternate minima that differ from standard values. This directly concerns how you plan an alternate in case the destination’s weather is unsuitable. The other options relate to cargo restrictions, aircraft speed, and fuel planning, which are not about the weather minimums for alternates.
