1. Wind vector. Display shown on the lower RHS of the EHSI. This shows the wind speed and relative direction and is calculated using TAS, drift, ground speed a few other parameters I can't remember. This is also fed on to the FMS for use in calculating fuel burn, etc.
2. Horizon attitude and heading only (magnetic heading must be manually inserted for the heading to be displayed and should be cross checked with the direct reading compass every 15 mins (ish))
