INTERIM REPORT – OPTIONS FOR CHANGE – ATTACHMENT B<br />

<strong>EASA</strong>.2009.OP.21<br />

OPS 1.873<br />

Electronic navigation data management<br />

(a) An operator shall not use a navigation database which supports an airborne navigation<br />

application as a primary means of navigation unless the navigation database supplier holds a<br />

Type 2 Letter of Acceptance (LoA) or equivalent.<br />

(b) If the operator’s supplier does not hold a Type 2 LoA or equivalent, the operator shall not<br />

use the electronic navigation data products unless the Authority has approved the operator’s<br />

procedures for ensuring that the process applied and the delivered products have met<br />

equivalent standards of integrity.<br />

(c) An operator shall not use electronic navigation data products for other navigation<br />

applications unless the Authority has approved the operator’s procedures for ensuring that<br />

the process applied and the delivered products have met standards of integrity acceptable<br />

for the intended use of the data.<br />

(d) An operator shall continue to monitor both the process and the products according to the<br />

requirements of OPS 1.035.<br />

(e) An operator shall implement procedures that ensure timely distribution and insertion of<br />

current and unaltered electronic navigation data to all aircraft that require it.<br />

Agency Opinion 01/2005<br />

On the acceptance of navigation database suppliers<br />

In the Agency’s view the best solution would certainly be that the industry organizes<br />

itself to verify the quality of the navigation data provided by the suppliers and used by<br />

the aircraft operators. Such an option, similar to that developed by IATA for the<br />

operational safety audit of its member airlines (IOSA).<br />

In line with the above policy a stand-alone document is produced which will be used<br />

for the investigation of navigation database suppliers in Europe and, after satisfactory<br />

results, for the issuance of a letter of acceptance (LoA). This document consists of<br />

“Conditions” and “Guidance”. Finally, to facilitate the work of the investigation team<br />

and to allow for a better preparation by the organisation to be assessed, a<br />

compliance checklist in line with the above document is provided. The letter of<br />

acceptance does not constitute a mandatory requirement since it is not a mandatory<br />

certification attesting compliance with a binding act. The letter of acceptance will not<br />

attest that the data produced by these organisations can be used by operators, but<br />
