What you’re not saying is that’s the maximum leakage allowed. Most actually put out a fraction of that and measured from 20 inches away it’s reduced by a factor of 100. 10 feet away it’s virtually undetectable. Your Wx radar is pushing enough power to be received back after going 640 miles.

I’m really enjoying this thread as I’m learning a lot of techniques.
Here is what I do(320):
If I have Autoscan:
99% of the time I Auto and chill.
1% of time i’ll flip into manual if I feel I need a better look bc the Auto function is making it look like end of days for tactical close in deviations.
Non Autoscan:
Start with 4-5 UP.
Adjust tilt during climb so to be about 0 passing low to mid 20s.
FL250 I go two clicks counterclockwise out of CAL gain to MAN gain.
i’d love to see more tips and tricks because I’m always learning.

Technique I picked up from NWA pilots that instructed on the plane when they first got it. Use Gain setting based on FL. I come out of CAL around 200. Max gain/max alt (39ish). Each click down is roughly 5,000 feet. One below Max/350. I do this to 3 below Max for approximately 250.

I think people who really understand the radar quite routinely take it out of auto. Check for zero calibration errors? Growing cells? Height of the cells out in front of you… it’s all there if you know how to use it.

If you use widget weather, there is literally no reason to ever leave it out of Auto. Curious if you're going to clear the tops of the cells in front of you? Sure. But the multi-threat radar is far superior than what a pilot can do using manual. That's like saying you're going to only fly VOR to VOR because GPS routes are scary

Except -1 tilt doesn’t give you that, you have to take into consideration beam width. If your radar is a 3 degrees beam width (+/- 1.5), a -1 tilt would give you an effective tilt of +.5 and a look 4000ft ABOVE your flight path, vs your 8000ft below at 80nm. Also, you need to know if your aircraft radar is horizon stabilized vs aircraft axis stabilized.
Never thought I’d have to correct an Eagle driver on radar mech 😜

The same math works for centering the beam, don't worry about beam width when crunching the numbers. Yes, you'll pick up above and below your target altitude but knowing where to center the beam is the most important aspect of using it.
Personal opinion only, I don't work for DL but was interested in this thread. I do not take my radar out of auto on the a/c equipped with it. We have some of NG's that have manual only where it is important to use tilt theory but on a/c equipped with auto, just leave it there IMO.

I cannot envision a reason to reduce gain except for one - you have absolutely zero options for penetrating a line of weather and it's all painting red+ everywhere, and you just want to know which of the red's are VIP 3's and which are 4's+.
For those who like to hug storms…did you notice that there was a lightning bolt that measured more than 500 miles? Yes, it is an outlier, but lightning and hail can be projected well away from the storm. The 5, 10, 20 numbers in the FOM are bogus and have no grounding in reality.

Beam width is the entire beam which means at 3* beam width and -1 tilt you're scanning from -2.5 to +0.5 already. The radar width is like a flashlight/cone of light. It's also important to know that the same energy at the -1* set tilt does not exist at the fringes of the beam.

Lightning strikes in the flight levels are of little concern IMO.

It works well. That’s why people have different techniques.

I remember doing the trick where the video is projected in a classroom on a whiteboard, and you trace Archie's facial features with a marker. Hours later, his face still remains in the exact same spot.

This. Auto + widget weather is more than enough.
Understanding the nuances of manual radar are interesting and help pass the the time.
So is celestial navigation.
There's a reason we're not issued sextants.
