Hello everyone, Dick Rochfort here. Subscriber WESTECLD has asked "why the cabin altitude is above 10k in this video". This is a good question. The PA46 is capable of a 5.5 PSI pressure differential on the cabin which can keep the cabin altitude at sea level when operating at or below 12k ft MSL. Once the cabin pressure systems gets to its maximum 5.5 PSI, the cabin will climb with the aircraft. this will yield a 10k cabin when cruising at FL280. While a 10k cabin is not ideal, it is usually far better than slugging through weather at a lower altitude. Fly Safely - Train Often
Richard, 1st of all I must express my personal gratitude for your contribution to aviation world, at the same time I would like to ask you what if the ice formation happens in the darkness of night when the visual contact with the leading edge of the flying surfaces of the plane is impaired? At the mean time I must enviously say that I want your job....Happy landing
Hi Aryajet, airframe ice at night requires the same action and adjudication at night as during the day. There is an ice light on the leading edge of the left wing to help with identification. There is also less sublimation at night. Fly Safely - TsIn Often DR
You mention that “window heat/anti-ice” is “delicate”, what do you mean by that? All commercial jets fly with window heat on for the entire duration of their flights. No worries about ice breaking off the window and damaging the tail/ tail boots?
The PA46 FIKI system is effective within the limits of its certification. Jets have hot bleed air for the wings and the windshield.. an effectively unlimited supply. A PIREP of light ice made by a jet aircraft should be noted by the PA46 pilot and that area should be avoided. Light ice for one is not the same for the other. The PA46 has some areas which are unprotected such as wing and stabilizer tips, cowling, prop spinner and so on. The aircraft will experience a loss of airspeed long before ice can break off the windshield. The whole system needs to be used within the strict limitations of the certification.

Hi Chris, Thanks for tuning in. You can find much more on various topics including radar at my PA46 Pilot Reference Library o. My website rwrpilottraining.com ..Fly Safely - Train Often
Negative; any loss, of airspeed attributed to airframe ice is considered severe ice, and it is to be strictly avoided. I do this by never intentionally encountering any area forecasted to have more than light ice. Remember definition of light. It is ice which goes away completely when you activate the equipment and does not return. Any loss of airspeed is severe and anything in between is light to moderate. Be sure to understand this before you venture into areas of potential ice. Fly Safely - Train Often .. DR

Excellent commentary - made the video the video interesting and I learned a few things about icing. Thanks!
I am happy to help.. Fly Safely - Train Often .. DR

understood love your videos, and im nuts about pa 46
Me too! Fly Safely - Train Often .. DR
I still love this vid, been out of comm flying for 6 months now, kinda miss the ice... weird lol
Yes indeed! Fly Safely - Train Often .. DR
I would like to see more in depth on the Meridian radar how you use it in the all the functions

Do you not wait to see an airspeed drop before turning on the boots? You mentioned no airspeed drop.

When the ice begins to clear from the windscreen the pilot can assume it is also clearing from other unprotected surfaces.

Why is the cabin above 10K in this vid?
On low density altitude days at higher altitudes, the cabin can go above 10,000. This is normal. Fly Safely - Train Often .. DR
Flying on instruments he doesn't need to see out the windscreen.
Until you are needing to land.. Fly Safely - Train Often .. DR
