MODUK - DEF STAN 00-970: PART 9

Design and Airworthiness Requirements for Service Aircraft - Part 9 Remotely Piloted Air Systems

inactive
Organization: MODUK
Publication Date: 20 July 2012
Status: inactive
Page Count: 54
scope:

The mandatory requirements set out in this standard are those basic requirements needed for the design and development of airworthy RPAS for all three UK Armed Services.

In addition to the mandatory requirements set out in this document, the airworthiness standards set out in NATO STANAG 4671 Unmanned Aerial Vehicles System Airworthiness Requirements (USAR) Edition 2 are also mandated, supplemented by the following UK national reservations. NB the terms RPAS, RPAV as used in Def Stan 00-970 and UAS, UAV as used in STANAG 4671 are interchangeable.

UK national reservations:

Amend USAR paragraph U50. Insert new paragraph U50(c) Demonstrate that there is adequate margin (e.g. 15%, to be agreed with the Certifying Authority) between Vs and Vmin FCS (i.e. to take account of gust) and that Vmin FCS is robust.

Insert after USAR paragraph 201(ii). iii) VminDEMO to be equivalent to VminFCS

Amend USAR paragraph AMC.1309(b). Insert the additional sentence at (5)(c)(i). more severe criteria may be needed for large aircraft;

Insert the additional sub-paragraphs after (5)(c)(1).

For large aircraft from 5,700kg up to 20,000kg MTOW (with the exception of propeller-driven twin-engine RPAS, refer paragraph B). At RPAV system level, the combination of all Catastrophic failure conditions is characterised by an occurrence of 10-6 per flying hour or less (with the calculation method subject to Certifying Authority agreement).

For propeller-driven twin-engine RPAS from 8,618kg up to 20,000kg MTOW, at RPAV system level, the combination of all Catastrophic failure conditions is characterised by an occurrence of 10-6 per flying hour or less (with the calculation method subject to Certifying Authority agreement).

In the event that there are discrepancies in the airworthiness requirements contained in STANAG 4671 and Def Stan 00-970 Part 9 then the requirements in Def Stan 00-970 are to take precedence. However, in such circumstances MAA-Cert-ADS1 is to be advised.

Unmanned dirigibles - Until the release of an EASA Certification Specification compliance with the requirements of either of the documents referenced within Part 15 for the design of dirigibles will be considered by the authority; however the requirements specific to RPAS (e.g. DATA Link, GCS) within this document are mandated.

At present this standard does not cover the following:

Aircraft (with a previously issued Design Certificate and a Military Aircraft Release) that have been converted from a manned to an unmanned role.
