Aerospace Instrument-Making Annotation << Back Choice of the preferable SID of an aircraft from all SID’s attributed to the runway N.A. Golovanov, N.A. Zaytseva, I.V. Kalinina, T.P. Tkacheva Article is devoted to definition of the Standard Instrument Departure (SID), recommended to performance, attributed to one runway in process preflight planning. The criteria of a choice recommended SID are based on sizes of available and required gradients of a set of altitude, on the minimized flight time under the SID, and also on the minimized vertical speed. The tech-nique of definition of the recommended SID is resulted. The results of modeling are applied.
