Go Around procedure for 757

Recommended Posts

Hi,Can someone please tell me how to negotiate a go around in the 757. Other than disconnecting the A/P and flying manually is there another way. many thanksKeith

Well, another option would be to press the TO/GA button on the thrust rating panel to the right of the upper EICAS. This will command go-around power. Then, I'd just engage heading hold, dial in a comfortable vertical speed and start the climb and flap retraction.Once you're a little less 'busy' you can switch to FL CH mode for the climb to maintain a desired speed or just continue to use V/S in conjunction with a selected speed.However, if you're in a hurry and trying to execute a quick go-around, I still think it's your best bet to press the disengage bar and fly by hand -- you can always re-engage the autopilot later if you want and you'll never be able to beat your ability to react quickly at the outset. :)

Oh, and one other thing (sorry about the two posts, but I got some weird message about the 'editing period having expired' when I tried to modify my original post) -- pressing the TO/GA button is advisable anyway even if you later disconnect all parts of the autoflight system, because it will also change what you see on the flight director. :)

Victor,Thanks, this is what I did try initially but for some reason pressing the TOGA button did not have any influence on anything. It just does not work.However, I will try again later.thanks againKeith

Hi,- engage G/A mode- observe G/A power being set by A/T (if problems, firewall throttles manually)- select FLAP20 (both engines operating)- @ positive rate: gear UP- @400ft AGL select lateral mode (LNAV, HDG SEL)- @1000ft AGL select vertical mode (FL CH Vref+80)- Clean up and fly the missed approach procedure and contact ATC to let them know about going around.Observe 2000fpm climb rate during go-around and the eventual thrust reduction after that ROC is achieved (it's normal).Hope this helps,Tero

By the way, If you are still confused, make sure the A/T is armed (switch flipped) and RIGHT click the EPR button. For all these great hints here, I never saw mention of how to actually engage the GA mode. Hope this helps too!-adamP.S. I never got the TO/GA switch on the TRP to work. I eventually found the EPR TO/GA button when my mouse indavertantly hovered over the EPR button on the MCP.

Missed Approach/Go-Around - All Engines OperatingIf a missed approach is required following an autopilot approach, leave theautopilots engaged. Push either GA switch, call for flaps 20, ensure go-aroundthrust for the nominal climb rate is set and monitor autopilot performance. Retractthe landing gear after a positive rate of climb is indicated on the altimeter.At typical landing weights, actual thrust required for a normal go-around isusually considerably less than maximum go-around thrust. This provides a thrustmargin for windshear or other situations requiring maximum thrust. If full thrustis desired after thrust for the nominal climb rate has been established, advancethrust levers manually to maximum go-around thrust.If a missed approach is required following a manual instrument approach or visualapproach, push either GA switch, call for flaps 20, ensure/set go-around thrust,and rotate smoothly toward 15

I was using the correct procedure but it was the TOGA switch problem that Adam has pointed out, that wouldnt work. Now I know what to click on I will try again.Many thanksKeith
