@@shanelodge391correct. Both the flood light and the backup attitude indicator are powered for 90 minutes. The 30 minutes is for the battery powering the aircraft electrical systems.
It was a while ago so, I don't recall what my thinking was. I was a fairly new CFI at that point so, I suspect I thought it would be prudent for me to fly it. In hindsight, the student was more than capable of flying it home. The worst case scenario would have been no flaps if the electric failed. Being a CFI is a constant learning process. As with other certificates, passing the checkride is only the beginning of learning to be good at it.
interesting but as a budding instrument pilot closing in on his check ride and yet you are constantly touching the controls and actually took over control. Not really confidence inspiring.
ess bus switch is 30 minutes, emergency switch is 90 mins
your student was correct, you have 30 min. the caged battery backup works for 90 min. and only powers the back up attitude indicator
Doesn’t it also power a strip light under the panel ?

Why didn't you use the essential bus switch to help load shed?
I know this is an older vid... but why didn't you let the student fly home?
