Roger C Posted February 14, 2018 Report Share Posted February 14, 2018 I press my assigned keyboard key for Spoiler-the Pedestal view shows the spoiler lever going to the extend position but the airspeed does not reduce and exterior views show the spoilers still stowed. They work just fine on landing just not in the air. Link to comment Share on other sites More sharing options...
FeelThere Ariel Posted February 14, 2018 Report Share Posted February 14, 2018 Hello Roger, Could you show us a screenshot please? Also, if you have a log file, that would help us greatly! Kind regards, Ariel Link to comment Share on other sites More sharing options...
Roger C Posted February 14, 2018 Author Report Share Posted February 14, 2018 Here is the log..assuming this is the one needed. Frankly, screenshots are only going to show what I described-the spoiler handle in the extended position but the spoilers are still stowed in exterior views and on the EICAS diagram of spoiler/flaps extended. As well, there is no reduction in airspeed or indication of trending on the airspeed tape. e170.log Link to comment Share on other sites More sharing options...
FeelThere_Vic Posted February 14, 2018 Report Share Posted February 14, 2018 Can you please also tell us about the speed, altitude, etc. There are situations where the speedbrake deployment is not possible. Vic Link to comment Share on other sites More sharing options...
Roger C Posted February 14, 2018 Author Report Share Posted February 14, 2018 This has happened a few times but the most recent was descending through 8000' down to 4000' at 1500fpm with throttles at idle. Airspeed had been set to 210, and had been there during the early part of the descent. It rose to 260 at which time the speedbrake deployment was initiated. I have also experienced it during level flight on approach prior to glideslope capture when airspeed would not decrease (from 200 kts to a desired 160 kts) so speedbrakes were commanded but unable to deploy eben though the lever was in extended position.

scoobflight Posted February 15, 2018 Report Share Posted February 15, 2018 Roger: Throttle was at idle? You have confirmed that your control will set the throttle to idle? Link to comment Share on other sites More sharing options...
Roger C Posted February 16, 2018 Author Report Share Posted February 16, 2018 I believe I was in VNAV and the N1 settings were showing idle thrust. Yes, VNAV does reduce the thrust for descents if I understand what you were asking. Link to comment Share on other sites More sharing options...
scoobflight Posted February 16, 2018 Report Share Posted February 16, 2018 Roger: make sure your throttle controller (ie, what you use to control the throttle ... ie, the throttle lever on a CHYoke) is not giving any thrust indication. Link to comment Share on other sites More sharing options...
Shom Posted March 13, 2018 Report Share Posted March 13, 2018 @Roger C @scoobflight I've noticed the spoiler does not show for me on wing view (when looking from inside the cabin outside the window) unless extended over ~75%. However, it does show correctly when looking from external spot view/ control tower etc... (as long as not from within the cabin). Link to comment Share on other sites More sharing options...
