steps to improve mdcrs
Steps to Improve MDCRS
  • Current provide about 3,000,000 obs. per month.
  • Add carriers who operate in data-sparse regions
    • Alaska Airlines, America West, Frontier, Air Canada Jazz, USA3000, Trans States
    • Regional carriers with RJs that use ACARS
  • Reduce communication costs by selecting most useful observations through “Optimization”
    • Select by flight number and phase of flight
    • Reduce number of redundant observations
    • Encourage use of standard format for MDCRS messages – ARINC 620.
