So pushing the thrust levers up on a GA........ who would have thought? Nearly every student pilot would be able to guess that would be a good idea!
Let's look at how much Boeing trusts TOGA.....
Let's have a look at Windshear memory items:
Windshear TOGA
Thrust lever maximum (aggressively)
A/P disengage
A/T disengage
etc.....
Let's have a look at GPWS warning memory items:
A/P disengage
A/T disengage
Thrust lever maximum (aggressively)
etc....
Go Around procedure
TOGA Flap 15
Go Around attitude
Verify Go Around thrust
Positive rate Gear Up
At no point does Boeing suggest that pushing TOGA by itself is sufficient evidence that thrust has done as TOGA is supposed to do. In single syllables NEVER TRUST TOGA in critical situations, because if it doesn't do as you expect it to do, left uncorrected at a critical time, a disaster will ensue.
