Thank you all for your answers.
I was curious to know whether airliners used the same type of icing detection technology (MSO) that is used/being implemented in ground based automated icing detection, and the answer is yes.
Is it safe to assume that ALL airliners are equipped with this technology? 7X7/A3XX/MDXX ? What about regional jets?
In glass cockpits, is there an EICAS icing message that pops up?
On the low-tech side, is anyone aware of aircraft which have specifically designed protuberances that are visible from the cockpit and which were designed with the sole purpose of providing visual icing accretion indication to the pilots?
In small unpressurized pistons, the OAT probe is usually a good indication (by good I mean one that is a good ice accretor). I read somewhere that the "sharper" the object, the more it accretes ice.
Thanks again,
