What I mean is a "nose low" turn.
This can be a very low negative pitch angle.
You wont be able to read the HSI attitude for -.5 deg pitch but you can use the climb/dive needle to see a pitch that small. (Needle drives to "dive")
Nose low turns help to preserve/create air speed to help maintain your plane's best turn speed thereby maintaining your best "nose rate" in the turn.
But not so much as you add more distance to your turn.
The goal is to combine descent+throttle+WEP to help sustain speed through the turn.
This is not to mean that every time you do a lead turn you have full power selected.
If my plane's best "corner speed" is 250mph I may have to bleed speed in the turn to get there.
Still I got in the habit of "nose low" lead turns. I only to have to "meter" in throttle for my target speed.
If I find I need full power with nose low to stay near my best corner speed Im allready slightly nose low.
Btw, in a lead turn with a -.5 deg pitch componant, roll angle will be -89.5deg. (Climb/Dive indicator drives to "Dive")
A pure flat plane turn, roll angle = 90deg. (Climb/Dive indicator =0)
A climbing turn with +.5 deg pitch-- roll angle = 89.5 (Climb/Dive indicator drives to "Climb")
Beware, some plane's absolute best corner speed can be quite low. You may not feel comfortable dropping to that low of a speed/E state at the merge.
A happy combination of good "nose rate" AND good E retention (speed) is what I go for.
This combination may or may not be at my planes absolute best corner speed.
