Autothrottle is something you bang into FS aircraft without realising how few real aircraft have it. Modern light jets don't. ILS approaches are normally flown on autopilot with the pilot controlling speed manually. For an SRA you could use the AP on heading mode and set a rate of descent but then you have to be really careful interpreting any deviation in height and in dialling in a correcting value. bones -----Original Message----- From: jhb-bounce@xxxxxxxxxxxxx [mailto:jhb-bounce@xxxxxxxxxxxxx] On Behalf Of Gerry Winskill Sent: 23 August 2007 14:40 To: jhb@xxxxxxxxxxxxx Subject: [jhb] Radar Surveilance Approach Landing I'm not even sure that I have the words in the correct order, for what used to be a GCA Talkdown, to cover the context of my question. Whatever; in the hypothetical situation of a modern light jet, equipped with Autopilot and Autothrottle, being talked down, would the final 10 miles descent be conducted flying entirely manually? Or would autothrottle be used, to reduce the workload? Could the rate of descent be set initially using the AP? You can see I'm wriggling into a position where I can't escape the inevitable, and mind bogglingly embarassing, attempt at one. Gerry Winskill
