HMMM...
Hi Pembroke,
Not sure that I entirely agree with you on that one. The instructional flight is not intended to be a "test" as such. According to the CAA the FI should make clear the objectives of the flight, in order "to ascertain the applicants knowledge and skills, and interject if necessary to improve on these" . The CAA goes on to say that if the flight was for some other form of training, then the FI should se;ect suitable items of general handling to fulfil the putposes of the JAR-FCL requirements.
I would also refer you to Section F of LASORS Para 1.4, which states that "The training flight may be replaced by any other proficiency check, or skill test for an instrument, class or type rating, as defined by JAR-FCL with a JAA qualified examiner, OR by a flight test for the issue, revalidation, or renewal of a UK IMC rating.
As far as I can see a proficiency check could be conversion onto a new type of aeroplane.... as long as the instructor includes some basic general handling during the flight.
Please feel free to correct me if you feel that I have mis interpreted the JARs.
Cheers
