Abstract: Systems and methods to facilitate a steep final approach phase of flight of an aircraft are disclosed. In one embodiment, a method for operating an aircraft during a steep approach phase of flight of the aircraft comprises operating an engine of the aircraft at an idle speed associated with the steep approach type that is lower than an idle speed associated with a non-steep approach type capable of being executed by the aircraft. The method also comprises operating an ice protection system of the aircraft during the steep approach phase of flight of the aircraft.

Abstract: A method and associated device relate to the enhancement of a digital model of a building using a computer, wherein: a) the digital model is analyzed in order to identify the elements that make up the building and have specific characteristics in the building; b) construction products which have properties that match said characteristics are defined; and c) the digital model is enhanced by adding, for every element that makes up the model, data from at least one list of suitable construction products.
