Standard Computerized Airplane Performance (SCAP)

​Standardized data format

Standard Computerized Airplane Performance (SCAP) is a specification which defines the interface requirements for aircraft manufacturer supplied inflight performance software for implementation in the airline user environment. This Specification is applicable to Civil Transport Category airplanes.

How it works

All airlines must provide performance data to enable their flight crews to operate aircraft safely, economically and in accordance with their applicable certification rules and operating practices. Basic data has in the past been provided by the aircraft manufacturer in various manuals (AFM, Operations Manual, Performance Engineer's Manual) in hard copy form.

Progressively this has been supplemented by data provided on magnetic tape/floppy disk to facilitate data entry into programs developed by the airlines or by aircraft manufacturers. Aspects which require basic performance data applications include takeoff, landing, flight planning, route studies, engine failure procedures, and aircraft performance monitoring, etc.

In order to reduce the development effort for the airlines (interfacing with different airplane manufacturers' programs) and manufacturers (meeting individual airline requirements for customer-specific features) there are clear advantages in standardizing as much as possible the input/output features of these programs, and also data formats.

Standard Computerized Airplane Performance (SCAP) Working Group

Having recognized this potential benefit, IATA, ATA and several manufacturers set up the Standard Computerized Airplane Performance (SCAP) Working Group, which reports to the IATA Aircraft Performance Working Group (APWG). This specification is a result of the SCAP Working Group's efforts.
