Especially during take-off and climb phases, the air vehicles need the maximum power. Mainly, as presented in Figure 1, it is possible to handle the flight stages in 8 sections, 2 of which are runway maneuvers (Taxi). The cruise phase begins immediately after the climb phase is completed. In this stage, the fuel consumption is less than take-off and climb phases. Although it depends on the aircraft configuration and meteorological conditions, the descent phase, which usually takes place with a 3° nose angle, is one of the most critical stages. In this phase, the use of fuel is less than that of the cruise.eninfo:eu-repo/semantics/openAccessAttribution-NonCommercial-NoDerivs 3.0 United StatesGas turbine engineMaterial distributionArticle4110.31031/EME.2022.04.000576
