Deicing

[Dingle]

Hi all,
the Manual states: "Once in flight, the ice detectors will
activate the sequential boot inflation system when ice buildup is detected on the airframe. No
action is required of the pilot to deice the aircraft, and Crew Alerting System (CAS) messages
alert the pilot to deicing system failure; however, the pilot should always be vigilant in monitoring
for ice accretion on the airframe."

If I read this correct, that is it will inflate the boots automatically, but I still have to set the deicing switches? Or don't I? I am confused

Yes, the ice detectors will automatically detect the ice and shed it at the optimal time. Heated probes, windshields, and the inertial separators are up to you. The color of the icing message (yellow) on the EICAS will remind you if you have not activated all other deicing equipment.

Interesting. I had a yellow Icing caution yesterday passing through clouds. All the heaters were on, but the inertial separators were not. Would that do it?

I don't know, would be interesting to find out.

Can't think of anything else I missed. All heaters were on from the before takeoff checklist (I got a pitot overheat caution on the ground because I sat too long), windshields were on low... I did not have auto ignition on, either, and I'm still working my way through the manual.

Yes that's the engine deice! Anytime there's visual FOD (ice,snow,heavy rain) those should be turned on. You can see how much FOD and of what type on the engine's page in the tablet. Pretty helpful since not all occasions (like 20% snow) will show in sim!

I'm aware of the tablet visualization, but I was only in it for a minute or so and didn't think it bring it up at the time.

Normally I watch it ingest asphalt from what should be a paved ramp

@jmarkows Yes, that is one of the items.

@jmarkows if you watch the tablet for the engines, you can see the various type of FOD being ingested, dirt, rocks, snow, rain, sand etc. when you fly through clouds at altitude, you’ll see a snowflake so ice is a risk to do damage and you’ll see a snowflake ️ in the FOD area. Wouldn’t it be nice if real planes told you that, but I guess that’s why we have checklists and rules.
