ICAO doc. 9625 iss. 3 Implementation FAQ’s
April 17, 2020This document is a list of the more frequently asked questions we receive on the subject of ICAO document 9625 issue 3, along with answers and explanations.  Unfortunately the document continues to be misunderstood by a lot of people, erroneously thinking it is a new set of rules or regulations that can directly replace established rules such as JAR FSTD, FAR Part 60, or CS-FSTD.  These FAQ’a are intended to clarify the situation. You may also like to review two other documents in our File Repository on the same subject; – Recommendations for Implementing 9625 issue 3 – Tolerance & Technical Requirement differences between Doc 9625 issue 3 and JAR FSTD We are always interested in your comments, suggestions or additional questions, so if you have any please send them to us by clicking here…

Visual & Motion cues in the real world and in FSTD’s
April 17, 2020Papers were presented by the author, Ian W Strachan MBE AFC FRAeS, to conferences organised by the Royal Aeronautical Society Flight Simulation Group in London in April 1987, November 1989 and May 1990. These papers were entitled “Future Flight Simulation”, “Visual and motion Cueing” and “Future Helicopter Simulation”. The papers were refined to concentrate on cueing and expanded with more detail. In this form, a paper was presented at the Royal Aeronautical Society in May 1995. A further update was presented at the I/ITSEC training and simulation conference in Orlando, USA, in December 1997.  Subsequently the paper has been expanded and updated regularly with new information and distributed to those interested in simulator cueing, the latest revision in January 2014. Extra diagrams and material on visual cueing have been added, and new simulator test results incorporated in Annex G as they became available.

Fight Simulation – Viability vs. Liability
April 11, 2020This paper discusses the disturbing trend by companies to reduce the costs associated with the procurement of FSTD’s by removing steps perceived to be unnecessary.  The problem is that the people making the decisions are frequently, at the best, unaware of why these steps are required, or their value.  This paper discusses the subject of flight simulation viability versus liability…

The Process & Responsibilities of FSTD Procurements
April 11, 2020There is a growing and worrisome trend for individuals and companies to think that the acquisition of a FSTD is simply a matter of finding the financing and giving a manufacturer a purchase order and down-payment.  Unlike buying something like a car or even a house, the purchaser has a lot more to do, and carries a lot more personal liability. This document is intended to clarify the procurement process, be that purchase, lease or other acquisition, and who is responsible for what….

FSTD (A) – Flight Test Profile
April 11, 2020This profile is not intended to be a checklist for each type of evaluation, but as an aide memoire, to be used as a guide when planning Functions and Subjective Tests. It should be used in conjunction with an aircraft type specific evaluation document …

The QTG – Some Perspectives (past, present, future)
April 17, 2020This paper, by Malcolm Blackwood, provides an overview of the purpose and use of the Qualification Test Guide (QTG) that is used by all authorities to benchmark the configuration and performance of a FSTD when it is first qualified, and subsequently as a tool  to recurrently ensure the FSTD is maintained to that same standard. The paper supports a presentation made by Malcolm at a FSEMC Simulator Data Validation Exploratory Meeting in Crawley, United Kingdom, March 26 – 27. 2015.

The Modern QTG – where the Devil is really in the detail
January 14, 2022– There have been a number of discussions and meetings of late about Qualification Test Guides, and particularly if there is a case to be made to reduce the amount of recurrent testing of a FSTD.  It is a very contentious subject with one side saying that it is a waste of time and money as the results frequently do not show abnormalities. The other side saying if you use it properly you will always find problems even back to the original issue of the MQTG and besides, you don’t stop checking things (such as pilots competence or health) just because no problems were found on one test.      This paper was presented at a RAeS FSG  conference where significant discussion between regulatory authorities, operators, manufacturers and industry experts was conducted. The full proceedings of this and other topics will be published on the society’s web site. If you require further information or have any comments, please Contact Us

January 14, 2022Brian Hampson presented this paper at the June 2015  Royal Aeronautical Society’s  Flight Simulation Group conference.  It puts into perspective what the purpose of a QTG is, and more importantly what it is not. It is just as relevant today as it was when Brian presented it. If you require further information or have any comments, please  Contact Us
