(1 for arming, 2 for reversing). == Ronald -----Original Message----- From: Lancair Mailing List [mailto:lml@lancaironline.net] On Behalf Of Paul Miller Sent: Friday, October 18, 2013 3:49 PM To: lml@lancaironline.net Subject: [LML] Re: MT prop fully reversible 1st report... Ronald, does MT make a difference between "beta" and "reverse"? Beta in my experience is flat, zero thrust. Reverse is something else. In the TBM, beta provides a large percentage of the braking force that reverse does without kicking up debris. Can you determine where beta is on the MT versus reverse thrust? Those tests would be useful. Also, is "beta" prohibited below 70k or reverse or both? -- For archives and unsub http://mail.lancaironline.net:81/lists/lml/List.html
