Climbing away, TOGA, SRS, Open, Managed - any climb you desire.


Suddenly - you decide to stop climb. If you use the v/s zero method, if this can done then what would happen to your speed?


1/.You would accelerate?
2/.The aircraft would level but the speed would default to the climbspeed what was?
3/. The aircraft would settle down (given time) to a temporary cruise speed for that WAT.


My question is we were climbing and we stopped climb. (as opposed to simply levelling off) by this I mean.


(These are unfair questions - I should be paying you money).

One more, question, if I may . . .

This is nuts, but I did not say it - about TOGA from an approach:


They said, (I forgot who it was now) they said that selecting toga when dual CATIII would have the aircraft in the same mode but in TOGA power therefore increasing speed in the landing configuration they slightly dramatized this configuration. So:


Approaching CAT III Dual say, one parameter lost and/or for some reason you decide to go-around - I am just verifying that simply setting TOGA will simply not cut it. Therefore,


Acceleration Alt pre-set pull or push ASSUMING IT IS ABOVE YOU.
set TOGA thrust. Result =.............and/but . . if you move the T/L significantly by pulling back say then the a/p will disc, and you can fly to your climbing attitude, attitude?


So - by pulling or pushing the g/a alt, thus having been pre-set - will not work as all alts are locked out during a catIII dual approach.


Confused? Don`t be. Here is a different hypothesis.


Approaching CATIII Dual. All is stable, then application of full back sidestick, a/p drops out, nose pitches up, if above 100 r/a then alpha floor toga, climb . . vfe, clean as you go.


Summary


1/. By stopping climb - what happens to the rest of it - spd, accel?
2/. In a cancelled CATIII App - apart from disc a/p set TOGA and fly it out
can a breakout (if that is the right word . . ?) be performed with the pb`s without touching the sidestick - I say no. But I am only learning,


(a mere husk of meaning)
