A method for determining an aircraft minimum low pitch setting for a propeller assembly and a minimum gas generator idle speed for a gas generator, the propeller assembly and the gas generator together comprising a gas turbine engine of an aircraft, the method comprising: receiving, from one or more sensors, a weight on wheels, WoW, signal indicative of whether the aircraft is on the ground or in flight; receiving, from a throttle input device, a throttle lever position; and determining, via one or more controllers, an operating condition by: determining, via the one or more controllers, an idle condition of the gas generator based at least on the WoW signal and the throttle lever position; and determining, via the one or more controllers, a low pitch setting, LPS, of the propeller assembly based at least on the WoW signal and the throttle lever position; wherein the operating condition is one of: a ground condition where the LPS is a ground LPS and the idle condition is a ground idle condition, a takeoff condition where the LPS is a flight LPS and the idle condition is the ground idle condition, a flight condition where the LPS is the flight LPS and the idle condition is a flight idle condition, and a landing condition where the LPS is the ground LPS and the idle condition is the flight idle condition; and wherein the ground LPS defines a minimum pitch angle of the propeller assembly such that a minimal thrust is exerted. receiving, from one or more sensors, a weight on wheels, WoW, signal indicative of whether the aircraft is on the ground or in flight; receiving, from a throttle input device, a throttle lever position; and determining, via one or more controllers, an operating condition by: determining, via the one or more controllers, an idle condition of the gas generator based at least on the WoW signal and the throttle lever position; and determining, via the one or more controllers, a low pitch setting, LPS, of the propeller assembly based at least on the WoW signal and the throttle lever position; determining, via the one or more controllers, an idle condition of the gas generator based at least on the WoW signal and the throttle lever position; and determining, via the one or more controllers, a low pitch setting, LPS, of the propeller assembly based at least on the WoW signal and the throttle lever position; wherein the operating condition is one of: a ground condition where the LPS is a ground LPS and the idle condition is a ground idle condition, a takeoff condition where the LPS is a flight LPS and the idle condition is the ground idle condition, a flight condition where the LPS is the flight LPS and the idle condition is a flight idle condition, and a landing condition where the LPS is the ground LPS and the idle condition is the flight idle condition; and a ground condition where the LPS is a ground LPS and the idle condition is a ground idle condition, a takeoff condition where the LPS is a flight LPS and the idle condition is the ground idle condition, a flight condition where the LPS is the flight LPS and the idle condition is a flight idle condition, and a landing condition where the LPS is the ground LPS and the idle condition is the flight idle condition; and wherein the ground LPS defines a minimum pitch angle of the propeller assembly such that a minimal thrust is exerted.
