Description

Desired capability or behavior.

GASP has the following variables:

  • EMCRU: design cruise Mach number for engine sizing (not mission analysis)
  • HNCRU: design cruise altitude in feet
  • RWCRTX: ratio of cruise weight to gross weight for propulsion sizing (1.0)
  • RCCRU: rate of climb at cruise point

It is recommended that Aviary implement these features.

Research direction

Start by searching Aviary for existing GASP variable definitions and mappings, then inspect the related tests or variable-registration entry points. Compare the implementation with EMCRU, HNCRU, RWCRTX, and RCCRU as described in the issue. Done means Aviary exposes all four cruise-related variables with the stated meanings and appropriate test coverage.
