PS
As one poster noted: The F3 ADC does indeed stop at 850Kts! (Nothing bigger than 850 in the HUD) althought the Navs TAS (on the TV Tab) continues to read..... I would guess anyhow.....
There might be a viewer out there, who, may or may not have seen 900+ at LL (Where TAS=IAS or is as close as who cares)....... You Know Who You Are........ (Good luck mate, and love to the family)
Keep safe folks,
