MEL and push back

[Paulm1949]

Hi,

I realise the MEL is only active when aircraft is moving under its own power for take off. Although prudent to look at it anyway.

Question is say if you get a PACK light (etc) on after engine start but still connected to the tug? What do you do? What happens if they had disconnected the tug? NNC obviously but also back to stand ? Or continue ? Then MEL it on next sector with mx.

Thanks
