Abstract: A load weight and balance system has first sensors for providing a first output signal proportional to an available internal volume of an associated passenger luggage storage bin. Second sensors provide a second output signal proportional a weight of any luggage in the associated passenger luggage storage bin. Display devices provide a visual indication whether or not each passenger luggage storage bin is filled to capacity. A main display provides a visual indication of the storage status of all of the passenger luggage storage bins. A processor receives the signals from the first sensors and the second sensors, calculates whether or not each of the passenger luggage storage bins is filled to capacity and whether or not each of the passenger luggage storage bins is within a predetermined weight value, and determines whether or not the weight distribution of the passenger luggage storage bins in the aircraft is balanced.

Abstract: The present disclosure generally relates to systems and methods for determining a four-dimensional (4D) trajectory of an aircraft without requiring aircraft performance data or meteorological data. The techniques can include: detecting a plurality of 4D aircraft states of the aircraft, determining, for each of a plurality of pairs of adjacent aircraft states, a respective aircraft transition, detecting a plurality of pairs of repeat adjacent aircraft transition, discarding, for each pair of repeat adjacent aircraft transitions, a respective aircraft state from the plurality of aircraft states, and electronically transmitting the plurality of aircraft states after the discarding.

Abstract: A cabin pressure assessment system for an aircraft includes a plurality of polling devices within an internal cabin of the aircraft. The plurality of polling devices are associated with passenger seats onboard the aircraft. A cabin pressure assessment control unit is communicatively coupled to the plurality of polling devices. The cabin pressure assessment control unit is configured to receive cabin pressure comfort data from the plurality of polling devices.
