Video; test flying the Gulfstream G650 . . .
The auto throttle does work on single engine - your just not allowed to use for landing.. Auto brakes would be "nice" to have - agree - however to my knowledge you don't get any performance benefit from having them - so not really a big deal, if you ask me. 
I like the 650 - bring it on!

Having only done auto-lands with auto throttle and auto brake, how does Gulfstream manage it? Cant be much fun braking, particularly single engine, with no vis!

juliet: The Gulfstream series aircraft do not have autoland/Cat III, so the need for autobraking etc is not warranted. This should answer your core question.
The autothrottle works fine during most phases of single engine flight, but it is not certified for use on approach after the FAF. Best explanation I have heard, is that the autothrottle lacks 'finesse', so it tends to induce relatively rapid changes in rudder trim during speed and configuration changes on approach. That, plus the rudder is not directly controlled by the autopilot*. It is therefore best that the flying pilot manually changes power and trim to avoid control problems. If anyone else has heard a better explanation, please share!
Having an awareness of throttle position and engine response when single engine is also important in the landing phase: without a certified autoland function, the flare and touchdown must be hand-flown. Nice to know how the aircraft is behaving.
* Technically, yaw damper is an autopilot function that uses the rudder, but this is used for the control of dutch roll in normal flight conditions.

Thanks for explaining that envoy.
With the G650 being FBW though, do you have any idea why Gulfstream haven't sorted out the control issues you mentioned? I would have thought it would be fairly easy to sort out.
Im quite surprised that there is no autoland capability. The flight deck looks pretty capable, so Im guessing its a conscious decision revolving around perceived need? Compared to an airliner perhaps a business jet operation can afford to wait a couple of hours?

yes....
I just have to question his landing technique...both hands on the yolk...hmmm low energy go around anyone...?
scary..but then again, most journalists are no pros on the subjects they write about...but, yes it is horrible & frightening to see such bad airmanship...

Brian, thank you
Thank you again. The invective against "journos" is so all-consuming on this site that it
is an extraordinary breath of fresh air to hear actual rational thought. (And I'm not one of those feared journos,either - I just respect a great deal of their work.)

Surprised to hear that the autothrottles cannot be used in the OEI case beyond the FAF. The Global 6000 Vision ATS can do the approach and go-around with autothrottles coupled.
