FMC DEC Forecast question

Recommended Posts

Hi captains, quick question.On the FMC DEC Forecast page R1 LSK, what does the "TAI/ON ALT" stand for?I've looked in the FMC manual but I cant seem to find a read up on it. Either that or I've missed it.A straight answer to my question would be much appreciated :(

You can tell the aircraft what altitude you plan on using 'Anti Ice' so it can recompute the VNAV path during descent due to a higher Idle thrust.Rob

..well my guess was close. I thought it was something to do with tail Anti-Ice or something , but then I thought noooo that can't be right so I asked here. :( Thankyou Rob, your answer came right on time, due for descent in 2 hours. :(
