Bingo! Finally someone said something meaningful. Back in the day airlines were using Archie Tremmel Weather Radar course, where tilt management was taught properly. Many pilots do not use the till in a meaningful way. 1:60 rule along with proper gain is a great way to estimate the cloud tops. But we have to remember that the radar top( what radar detects) and the actual cloud top differ. Archie recommend to add 20% on top of the radar top when calculating cloud heights. Now if one must fly over the weather it has to be at least 5000' above the actual top. Everything else calls for deviation, preferably on the upwind side to reduce the effect of the turbulence.

So a 5 mW microwave puts out .005 watts. In your example, the Collins radar puts out 30,000 times the radiation of a microwave. (150 W / .005 W =30,000)
I have no clue about the accuracy of the claimed power numbers, just reworking the math.

Huh? 1 milliwatt = .001 watts. You divide by 1000.

All of this discussion is good but it one thing nobody has said is what about the possibility of a distraction like the WiFi, I’m surprised at the prevalence of pilots connecting to the free wifi and catching up on texts and social in cruise as if it’s totally acceptable.

Gotta disagree. I don’t mean this as a challenge at all, but If one understands how to manipulate the radar, a TON of additional information and SA can be gained. Simply understanding the 60:1 rule will give you an idea of tops/returns at an altitude just by using the tilt and doing the math. (-1* tilt at 80 miles = 8000 feet below you) It’s just one tool in the box, but the auto mode can often show irrelevant ‘cells’ similar-looking to legitimate threats, especially at range.
20 years of military use of radar also gives a level of comfort an understanding with instances to use manual modes. There is some decent info in the FCTM about wx/turbulence/radar, and used to me more in the Vol2

The Multiscan radar in auto is literally an easy button
