To measure airspeed I guess something has to have air flowing through it or past it, and that something would be susceptible to icing. That said, current pitot have very good ice protection, and AF447 was an extreme example with a known problematic type that Air France were in the process of exchanging.
Perhaps GPS ground speed data with previous wind estimates could at least help with establishing that "something must be wrong with the airspeeds".

Something scary from a Boeing pilot in the comments: Loss of all airspeed indications is not something we train for. It's always assumed in transport category aircraft that redundancies built in will always give us at least attitude, heading, and airspeed.
- caf 15y agoThere are meterological radars that use doppler shift to measure wind speed, I wonder if you could use the same basic idea to construct a radar airspeed indicator?
