Abstract: An embodiment uses a symmetrical elastomeric design with hydraulic pistons on either end (as opposed to a single piston on conventional BOPs) which allows for lower actuation forces, reduced friction, and reduced wear and tear. The lower actuation forces correspond to lower operating pressures which allows the body and housing to be smaller, leading to a smaller footprint.

Abstract: Methods and systems of generating a data driven digital chart. The methods and systems include retrieving a data driven chart for a requested terminal area procedure chart from a database of data driven charts. The data driven charts describe digital terminal area procedure charts by way of data elements for each terminal area procedure chart including geodetic straights, arcs, text elements and symbols defined with respect to location. Some of the data elements are further defined with respect to altitude values assuming a standard atmospheric temperature value. The systems and methods include calculating compensated altitude values for the data elements of the retrieved data driven chart based on a deviation between the outside air temperature value and the standard atmospheric temperature value. The methods and systems include generating a presentation for a display device of the aircraft of the terminal area procedure chart.
