A system of hardware and software for determining the weight and center of gravity location of an airplane or other vehicles, like a forklift, truck, maritime vessel. The same system could be used to determine stresses or movement on stationary structures is disclosed. This system employs commercially available, off the shelf or existing, proven, and inexpensive technology and utilizes empirical data. Further, it is designed as a supplemental check on calculated results, which are subject to data errors and are circumvented by this invention's equipment. The system includes a set of pressure and load, strain, bending, and/or other sensors, a voltage source, a voltmeter, a computer, a display, an empirically derived database, a temperature sensor, a set of switches, wireless transmission, and a power source that allows the system to be used for determining the weight and center of gravity location of an airplane or other vehicle.

Aircraft landing gear strut breakout friction values are used to correct measured strut pressure as related to the amount of weight supported; with the ability to generate and refine the breakout friction value database, and a farther ability to predict a future breakout friction correction value by trending historical measurements, as compared to recent measurements, as further compared to real-time breakout friction values. The system is used in monitoring, measuring, computing and displaying the weight and center of gravity for aircraft utilizing telescopic oleo landing gear struts. Pressure sensors, temperature sensors, humidity sensors, axle deflection sensors, accelerometers, inclinometers are mounted in relation to each of the landing gear struts to monitor, measure and record strut pressure as related to strut telescopic movement, rates of strut telescopic movement, axle deflection, current temperature, current relative humidity, vertical acceleration; experienced by landing gear struts, as the aircraft proceeds through typical ground and flight operations.

Vertical take-off and landing (VTOL) aircraft can provide opportunities to incorporate aerial transportation into transportation networks for cities and metropolitan areas. However, VTOL aircraft can be sensitive to uneven weight distributions, e.g., the payload of an aircraft is primarily loaded in the front, back, left, or right. When the aircraft is loaded unevenly, the center of mass of the aircraft may shift substantially enough to negatively impact performance of the aircraft. Thus, in turn, there is an opportunity that the VTOL may be loaded unevenly if seating, luggage placement, and/or positions of internal components are not coordinated. Among other advantages, dynamically assigning the payloads and adjusting components of the VTOL aircraft can increase VTOL safety by ensuring the VTOL aircraft is loaded evenly and meets all weight requirements; can increase transportation efficiency by increasing rider throughput; and can increase the availability of the VTOL services to all potential riders.

Delivery landing pads for unmanned aerial vehicles (UAVs) are disclosed. A disclosed landing pad to support a UAV includes a landing surface, and a pressure sensor operatively coupled to the landing surface. The landing pad also includes a processor to determine a presence of the UAV on the landing pad and calculate a weight of a payload transported by the UAV based on a measurement of the pressure sensor to determine whether the payload has been delivered to the landing pad.
