Conducting flight operations in oceanic and remote airspace may use data link communications systems (i.e., Future Air Navigation System (FANS) (FANS-1/A or equivalent)


Beginning December 12, 2013: ADS-B Out in Australia, Canada’s Hudson Bay, Hong Kong, Singapore, Fiji, Viet Nam and the Republic of China at or above FL290 are required to transmit ADS-B (Automatic Dependent Surveillance – Broadcast) Information

Beginning June 2018: New submission requirements developed for approval of RNP approval (A-RNP, RNP 2, RNP 4 and RNP 10) for Oceanic and Remote Continental Operations for both B036 (LRNS) and B054 (SLRNS).

Beginning February 2018: AC 20-140 modified the Compliance for RSP and RCP and matters related to communication management systems need to meet TSO-160 guidelines and the need for “Push to Load” capability for not only DCL but enroute updates related to VDL Mode 2 which also affects latency requirements.  Performance based Communication and Surveillance (PBCS)

Beginning October 2017:  New Data Link Compliance Requirements


Beginning February 5, 2015: specified portions of NAT minimum navigation performance specification (NAT MNPS) airspace will require these capabilities.

Beginning February 7, 2013: FANS-1/A (or equivalent) CPDLC and ADS-C implemented on specified tracks and flight levels within the NAT organized track system (OTS).


            Will you be ready?


To obtain this authority in the form of either an Operations Specification or Letter of Authorization (identified as A056, Data Link Communications under US Law) requires that the regulatory authority verify the following capability:


  1. Equipment and systems certification, and airworthiness approval review

  2. The required communication performance

  3. The AFM

  4. Additional MEL requirements and relief 

  5. Other elements necessary for the safe and effective use of data link communications


Initially, operators were capable of submitting a simple letter, proof of training and appropriate aircraft documents and the authority was issued. However, in recent months all regulatory authorities have increased the requirements for such requests to the point they now require not only a substantial submission package but references to such operations in detail within the operators Standard Practices Manual.


D & D Aviation has successfully accomplished approvals for our Worldwide clientele in multiple regulatory authorities from the initial request letter to the current, cumbersome application process. We have been successful because of our Dependable Document System with integrated products all working together to fulfill your aviation needs. The criteria evaluated to issue this authorization consist of three basic elements:


  1. The OPERATOR'S aircraft complies with the requirements.

  2. The OPERATOR'S maintenance program complies with the requirements.

  3. The OPERATOR has adopted Data Link Communication operating policies and procedures for pilots.


D & D Aviation Services will assemble all of the required applications and manuals from the customer’s information and responses to D & D Aviation’s proprietary Checklists and Questionnaires’ and then customize the associated Standard Practices and Policies Manual.


For Operators Needing Global Operations: Our “International Procedures Manual” was designed to address all of the required information and components to meet the issuance of all necessary Approvals including RVSM and any Navigational Approvals Required to conduct Global Operations including MNPS, RNP-10/5/4/1, BRNAV, P-RNAV, FANs 1/A+ including CPDLC procedures, ADS-C and ADS-B Out authority. The International Procedures Manual contains explicit policies and defined procedures as required by the Regulatory Authority. Our design eliminates the need to carry not only a Standard Practices Manual for RVSM, a Standard Practices Manual for International Operations and a separate Approved Maintenance Program to meet the requirements, thus reducing the number of documents on the aircraft.


D & D has written literally thousands of MELs for aviation's premier operators, including some of the aircraft manufacturers own demonstration aircraft as well as some regulatory authorities aircraft.


34 FAA Offices, in ALL 9 regions, utilize D & D Manuals as reference and example material for its inspectors and Stake Holders.


Regardless of the type of aircraft you operate, you can benefit from reduced mission cancellations by having a D&D MEL or Maintenance and Operations Procedures Document for your aircraft. 

In this day and age when time is crucial and money is tight, why not rest easy and leave the writing of your MEL to the professionals?
