Ever wondered why IndiGo has faced so many in-flight engine shutdowns linked to low-pressure turbines on Airbus A320neos, while Go Air hasn't? Turns out it's all about how IndiGo flies its jets. #AvGeek IndiGo follows a practice of revving Airbus A320neo jets at full thrust right after takeoff that could wear down the engines, an investigation by India's DGCA found. Go Air, which uses a so-called alt-climb approach that applies less thrust, hasn't had any such issuers this year.
