ED Decision 2017/021/R Issuing Certification Specifications and Guidance Material for Aerodrome Design (CS ADR-DSN) ‘CS ADR-DSN — Issue 4’.

The objective of this Decision is to update the certification specifications for aerodromes design (CS-ADR-DSN) in line with
the ICAO developments and other technical improvements, and to maintain a high level of safety of aerodromes design.
EASA is proposing this re-issue of CS-ADR-DSN in order to support and facilitate the aerodrome operators and airport
industry together with the respective competent authorities that are currently performing a certification process
following Commission Regulation (EU) No 139/2014.
This Decision amends CS-ADR-DSN in accordance with the respective ICAO standards and recommended practices
(SARPs) of ICAO Annex 14, ‘Aerodromes’, Volume I, ‘Aerodrome Design and Operations’ (ICAO Annex 14, ‘Aerodromes’,
Volume I), Amendment 13-A (ICAO State Letter AN 4/1.2.26-16/19).
Additionally, this Decision incorporates the amendments to the current aerodrome design requirements related to the
aerodrome reference code (ARC), the runway, shoulders and strip widths and separation distances between runways and
taxiways as an outcome of the work conducted both by the ICAO Aerodrome Reference Code Task Force (ARC TF) and
EASA under the initiative on accommodating large aircraft at existing aerodromes. These changes are, therefore, adopted
by EASA in advance of ICAO which is expected to adopt the same changes in the respective SARPs in 2018.
This Decision also addresses some recommendations and comments received from stakeholders and it encompasses
corrections and some administrative changes for better clarity of the text, unification of references, etc.
The amendments to the design characteristics, and in particular those related to the ARC, are expected to generate cost
savings for the operators of code D, E and F aerodromes due to lower construction and maintenance costs, and to
produce environmental benefits. In addition, they will provide greater opportunities for the airlines since large aircraft
will be able to operate at aerodromes where the existing infrastructure is not fulfilling the current code F aerodrome
requirements, while fully sustaining the existing high level of safety.

FAA SAFO 17013 Rockwell Collins FMS Pro Line 4 and Pro Line 21 Databases

Purpose: This SAFO informs the operators of Rockwell Collins Flight Management Systems (FMS) Pro Line 4 and Pro Line 21 FMS of the reinstatement of approximately 10,000 approach procedures and provides awareness to flightcrews of the new Rockwell Collins Temperature Compensation Limitations. The approach procedures will be reinstated in the 12/14/2017 navigation database update.

Background: During flight inspection, an operator observed the FMS map displaying an incorrect turn for the CYXJ (Fort St John) ILS Runway 29 missed approach while using temperature compensation (aircraft CRJ-200 with Pro Line 4 FMS 4.2). The operator assumed this was only with the map display and reported this issue to Rockwell Collins. Rockwell Collins determined that if the crew manually edits or temperature-compensates a “Climb to” altitude, the FMS removes the database turn direction (if any) on the following leg if the leg is Course-to-Fix or Direct-to-Fix. After sequencing the “Climb to” leg, the FMS will turn in the wrong direction if the required turn direction is not the most direct. This can occur in departures and missed approaches.
