This article aimed to analyze how the decision ladder can be used to evaluate emergency situations in aircraft, assist in identifying relevant information, and even improve existing procedures. A case study was conducted based on a real occurrence of an emergency light indicating the presence of metallic particles in a Black Hawk helicopter transmission oil flying in the Amazonian scenario. Based on the decision ladder methodology, it was verified that the occurrence analyzed was not correctly addressed in the flight manual and there would be a need for the inclusion of a new emergency procedure in the flight manual, which would allow the crew to separate a situation of major risk from one of minor risk.
