Approach in heavy ice condition
Hi
What would you do if you have to fly an approach in heavy ice conditions. Are the wing anti ice, engine anti ice, etc enough or would you prefer to fly the initial phase of the approach at a faster than normal speed to increase the TAT? ( Do you think that faster than 250 ias could be necessary? )
And what happens when we have to slow down to the final approach speed ?
If we fly the approach with AP and AT on, what would you do if the pitot tube dont give us "the true" because of ice formation. What I think : AT disconnect and flying with nomal engine indications. I want to know from the pros whats the procedure.
If we are on a descend with FLCH mode, and that happens, I think we have to disconnect as fast as possible the AP to avoid pitching down or up do to false ias indication or going to CWS mode. ( again, whats the procedure here )
Thank you very much
