A method for extending a landing gear system for a vehicle is disclosed. The landing gear system includes a first landing gear assembly and a second landing gear assembly. The method includes the steps of sensing a first load on the first landing gear assembly after the first landing gear assembly has reached a wheels-on-ground state and comparing the first load to a first target value. The method further includes the step of controlling an extension speed of the first landing gear assembly according to a difference between the first load and the first target value.

A system for monitoring impact on an electric aircraft is presented. The system includes a sensor communicatively connected to a flight component, wherein the sensor is configured to detect a measured force datum and generate an impact datum as a function of the measured force datum. The system further includes a computing device configured to simulate a landing performance model output as a function of the impact datum, generate a landing performance datum as a function of a comparison between the landing performance model output, determine an alert datum as a function of the landing performance datum, and display the landing performance datum on a user device.

An aircraft control system 100 operably connected to a landing gear and a landing gear bay door of an aircraft 400. The system includes: a user interface 10 to receive manual inputs of first and second requests and a landing gear controller 20 configured to: receive a first indication indicative of user-operation of the user interface to input the first request, and to initiate movement of the landing gear bay door from a closed position to an open position on the basis of the first indication without initiating movement of the landing gear between an extended position and a retracted position; and receive a second indication indicative of user-operation of the user interface to input the second request, and to initiate movement of the landing gear between the extended position and the retracted position on the basis of the second indication.

An up-lock apparatus for landing gear of an aircraft includes a hook member configured to receive an up-lock roller pin of the landing gear when the landing gear is retracted. An up-lock actuator is coupled to the hook member and is configured to maintain the hook member in a locked state responsive to a first movement of the up-lock roller pin against the hook member to thereby prevent deployment of the landing gear. The up-lock actuator is further configured to allow the hook member to move to a released state responsive to a second movement of the up-lock roller pin against the hook member to facilitate deployment of the landing gear.

An EHA system (10) for lifting or lowering a leg of an aircraft includes a hydraulic circuit (101) having a hydraulic actuator (a hydraulic cylinder 2) configured to lift or lower the leg, at least one electric hydraulic pump (3), and a hydraulic path, a pressure sensor (38, 83), a temperature sensor (84), and a control unit (a controller 9) configured to output a control signal for operating the electric hydraulic pump in leg lifting or lowering. The hydraulic circuit includes a pressure increasing element. The control unit performs health monitoring regarding the performance of the electric hydraulic pump based on the pressure of hydraulic fluid, the temperature of hydraulic fluid, and the speed of the electric hydraulic pump during operation of the electric hydraulic pump.

A method of warning of early rotation of an aircraft during takeoff is disclosed. An improvement in aircraft performance and passenger comfort can be realised by monitoring for signs of early rotation and warning the pilot of such. By detecting when rotation has been commanded by the pilot, and the aircraft nose has started to lift off the ground, when the speed of the aircraft is below a threshold, early rotation can be determined and an auditory warning can mitigate the impact of that on aircraft performance.
