B777 single engine go around and TOGA switches

Question for the group. My apologies, I couldn’t find the answer in our manuals and am not near a simulator to find out for myself.

When initiating an airborne go around single engine, can you push either TOGA switch or do you have to push the one for the operating engine. In other words, does shutting down an engine inhibit the associated TOGA switch?

Thanks.

Why would you take your hand off the operating engine's thrust lever to operate the TOGA switch on the thrust lever that is at idle?

Iirc, pressing either TOGA switch will do the trick.

If you cannot see why it did not need answering, Airmanship is dead..

He asked a doubt, you’re going an about airmanship. Sarcasm breeds contempt. 🤦🏽‍♂️ I guess you had to answer, whilst not knowing what to write. QED

I think from memory you can press the little CON button on the Autothrottle section of glareshield display select panel..that gives you max continuous on whatever is working

"iceman50; If you cannot see why it did not need answering, Airmanship is dead.."

I can think of two possible airmanship reasons to use the dead engine's TOGA switch. Let's keep an open mind - we might learn something useful.

Either will work to give you TOGA.

A question is a question, why not answer it.

Please don't tell me you'd select CON thrust during a one-engine inoperative go-around (before flap retraction)...

Well, if you are sitting on the left hand side and engine one failed the TOGA button on the RH throttle is not easily reachable as your thumb is on the wrong side.

Why do you need your thumb? The TOGA switches are on the forward side of the thrust levers.

It can be quite a reach to get to the TO/GA switch if the thrust lever is already well advanced, especially if you’re going over the top of the retarded one. Also easy to think you’ve pressed it but the FMA says no, so try again. Whatever works and distracts you less from the task of flying the aeroplane...

Perantau, Wirbelsturm, thank you for your answers. Full wings, you are on the right track as to what prompted the question.

Recently a student in the sim attempted a single engine G/A but the thrust did not come up. He was adamant that he pushed the TOGA switch and I was wondering if he may have pushed a de-activated one. Now I am fairly certain that he touched the switch but didn’t actually push it hard enough to engage it.

Much less pushing the thrust lever...

Could I suggest that : If you can't reach the TOGA sw on the advanced thrust lever, you should better consider your seating position when you set up your cockpit.

Iceman might have been a bit snarky but surely the point he was making is valid. The inoperative engines thrust lever should be at idle. Why would you even think of touching it ?

Exactly. Why even need a toga switch. 🤷🏼‍♂️
