we all do our dd ,i have done extensive searches and feasibility studies if this project was worth investing into as a speculation.i have read many posts over time saying it would or wouldnt fly or there wasnt any research done by the main parties involved on this.or ,the big one ,it could never be certified...what we know..the integrity is based on the brit norman islander..iahl has at least 10 to 12 full fuselages and parts .i came to find some info submitted by a test pilot,in fact a world renouned test pilot who worked for brit norman in the past.he is a person of great aviation knowledge with build out ,structure variences and instrumental in planes getting certified.i have included a letter written by anthony brown on the subject of the integrity.i hope this solid proof finally puts to rest some of the nonsence that is being posted by several people with more of a personel vindictive agenda..,i truely feel that pvd is working hard at getting the funding they need to take this to the next level.ADDmONAL INFO: LEITER FROM TEST PILOT - ANTHONY BROWN
Engineering of the Integrity:
The Integrity is a highly innovative aeroplane design, which constitutes a further unique
development of the BN2 airframe. During my period as Head of Flight EngineeringfI'est Pilot
for Pilatus Britten-Norman Ltd, I oversaw, held responsibility and often conducted the
certification f1ight testing of a range of innovative configurations, including but not limited to:
(1) the BN2T with underwing Stingray torpedoes; (2) the AEW and ASTOR radar BN2T
variants, with outsize bulbous-nose radome and external fuselage-mounted APU pod; and; (3)
the BN2T. - 2R and - 4R variant precursors of the Defender 4000.
In each case, the aerodynamic alid strocturalloads demand introduced by the configuration
changes were substantial. Nevertheless, with the exception of the BN2T/Stingray configuration
(flight-tested and released as a military-registered variant, to the requirements of MoD(PE) at
Boscombe Down), public transport Type Certification was achieved through the course of
structural modification design, followed by rigorous developmental and certification flight test
of performance, flying qualities, engine, structure and systems.
Hence, based upon the above - related past flight test experience of these variants, I am
confident that the Integrity Airplane will be able to become fully certificated to EASA CS-23
(JAR23) and FAR 23 in the normal category, for unrestricted public transport operations.
