1. An enhanced L-band Digital Aeronautical Communications System (LDACS) comprising:
a plurality of LDACS ground stations; and
a plurality of LDACS airborne stations, each configured to communicate with the plurality of LDACS ground stations using an LDACS access stratum and using at least one Long-Term Evolution (LTE) security feature through a non-access stratum so that the LDACS access stratum remains untouched.
