Abstract: A method of establishing a runway approach procedure for an aircraft at a selected runway, comprises, for obstacles in the final approach segment of the flightpath and having obstacle range values greater than the datum range, calculating a missed approach surface height at a projected intersection of a missed approach surface with a descending vertical error budget surface and a corresponding Distance to Height of Missed Approach Surface from the runway (DHMAS). For obstacles in the final approach segment and having obstacle range values less than the datum range, a missed approach surface height and a corresponding DHMAS are calculated using ascending climb gradient requirements. All DHMAS values are compared, and a controlling obstacle is determined as the obstacle having a greatest DHMAS. A decision altitude for the controlling obstacle is calculated, and the runway approach procedure is updated with the decision altitude. Relativistic metadata other obstacles can also be calculated and stored.

Abstract: Provided is a process of dynamically creating a personalized workout video for a user. The process, including: obtaining a collection of workout video blocks; retrieving a user profile attribute from a user profile, the user profile attribute including a fitness goal or exercise constraint; selecting a first workout video block from the collection based on both the fitness goal or the exercise constraint and an intensity level or body-region grouping of the selected first workout video block; sending the first workout video block to a user device of the user; receiving after beginning to sending the first workout video block; selecting a second workout video block from the collection based on the feedback, the intensity of the second workout video block, and a body-region grouping of the second video block; and beginning to send the second workout video block, with one or more processors, to the user device.
