Are you sure about that 30 degrees on the 412/430? I'm all for steep but that seems excessive.
If you do the math on 1/2 mile at 500 feet, pretty comfortable in my opinion, you are getting just over 9 degrees of glideslope. At 50 knots groundspeed in zero wind you'll get about 750 fpm ROD.
35 knots and you're down to 300 fpm.
30 degrees gives you 1500 feet at 1/2 mile, 1350 fpm ROD at 50 knots, and 890 fpm at 35 knots. I'm not sure my collective goes that low
But you know me Xnr, I trim my turns.....would you trust my math????
