Here, we restructured chapter 9 and 10 and incorporated parts of these chapter to chapter 7.

In this WG final-call updated version, we added descriptions for possible future applications provided by LDACS, updated the security descriptions, corrected minor typos and updated abbreviations.

This was a major update for us since we added several pages about the foreseen security features in LDACS. With the definition of ICAO Doc. 9896 of LDACS as a Link Layer technology, providing access to the Aeronautical Telecommunications Network (ATN) within the Internet Protocol Suite (IPS) plans of ICAO, strong access controls and user- and control plane security, are a MUST for LDACS.

In this update we fixed some formulation issues in the security section on LDACS.

In this update we officially and fully introduced the requirements language by IETF. Also, we added some new, important references.
