“As I'm attending the Nov safety course, is there anything anybody would like me to ask Frank or Tim ?
Should I ask whether they think the heli would pass re-certification ? “
Ask the following: Since the Robinson helicopters are restricted from sideslip and out-of-trim flight can the R22 and R44 meet the requirements of the Certification Requirements for Normal Category Rotorcraft which require demonstration of both to include 90-degree sideslip and 10-degree out of trim.
Also ask them to explain how their rotor system that has an 18-degree offset behaves with a phase angle of 72-degrees as opposed to 90-degrees on other rotorheads. Ask them why on the various Robinson websites they address the Robinson rotorhead yet when they address gyroscopic precession they use a Bell related diagram.
