Abstract: An aircraft management system displays a primary flight display screen. The primary flight display screen has a predetermined height and includes a horizontal situation indicator (HSI). The aircraft management system includes a processor and a memory device operatively coupled to the processor. The memory device includes programmed computer instructions that instruct the processor to display the HSI for an aircraft. The HSI includes a receding perspective to simulate a three-dimensional (3D) object.

Abstract: An auction management system brokers, between a seller and a buyer, a discrete traffic block of an ad placement. The auction management system comprises a traffic block definition tool providing workflows for obtaining traffic block parameters defining the discrete traffic block, the traffic block parameters comprising: i) an identification of the ad placement; ii) a volume parameter defining the volume of traffic included in the discrete traffic block; iii) at least one duration parameter defining an active time period during which the volume of traffic included in the discrete traffic block will be provided; and iv) an auction parameter defining an expiration time before which buyers submit offers to purchase the discrete traffic block. A listing search tool provides web pages displaying a listing of a plurality of listed discrete traffic blocks. Each listed discrete traffic block comprises a discrete traffic block with an expiration time that has not yet passed.
