A computer program written in FORTRAN 77, for calculating drag polars of gas turbine powered aircraft in the en-route configuration is presented. The method includes a correction for compressibility effects. Applications to several civil aircraft (business and transport aircraft, turboprop and turbofan powered) are presented. They suggest that the low-speed polar is accurate within 10 to 15 counts, for normally used CL values. The drag polars with compressibility effects appear realistic for small angles of attack only.
