Q400 max:1020 climb:900 cruise:850

400 climbs at 850, cruises at 850 and t/o and landing are at 1020. Some 400s have a reduced rpm button which allows you to push it, go props 1020 while rpm stay at 850 unless you go around.

The EMB climbs at 100% of MAX which is somewhere around 1300 RPM and cruises at 85% (around 1100 RPM). We have a PAX comfort climb which calls for 90% (1175 RPM) above 10K but I'm not 100% about the numbers, like I’ve said it's been over a year since I've flown it. Our profile also calls for 170 kias in the climb until upper teens, but she’ll go or climb faster if needed.

Hey guys, what’s the diameter of your props. The EMB props are 10.5 ft in diameter and sit 18” off the ground. Just curious, the Q props looks huge and the Saab's look small (may not be but they do).

These are kinda misleading. The Q4 has 3 detents in the condition levers: 1020 (max), 900 (mcl), and 850 (mcr). At Qx we set climb to 850, but use the MCL power. Some other operator probably leaves the condition levers at 900 for climb. I wouldn't know though.

For landing we normally use 850 (we have that reduced NP button). The props stay at 850 until you either land, or run the power levers up to a set amount (ga) - then the reduced NP is canceled and the props run up to 1020. It's great for noise reduction on final.



And yes, I know, I'm probably a dork for even bringing this up.

We do the same. 850 and press MCL in the climb. Props are thirteen feet diameter plus a few inches.

The Q400 is the King of the Props. And I really hope Bomb gives the 400X, or Q500 as I've also heard it referred, the green light. The two biggest hurdles I heard were that the partner companies want to increase the price higher than Bomb marketing wants to go, Bomb wants it to be an incremental follow on aircraft. And frankly they don't have a launch customer yet. I've been told that once someone commits to it Bomb will roll it out. Obviously with some serious gear geometry changes, that tail getting mighty long.

Sgt, do you guys not have the Reduced Rpm button?

Oh yea, she'll go forward fast in a climb, you just have to work out the momentum down low. We have one that'll do 230 indicated at 1000 fpm up to about 18K, and by the time you level at FL280, you're around 180K. the last 10,000 feet of the climb usually works better at 700 fpm (min loss of indicated airspeed/1000 feet), then the last 3000 feet at around 500 fpm. It's a fun bird to fly.

Well that may be, but they sill climb on them and keep those load factors up there toward the maximum. They may "care" but they'll crawl onto a CRJ200 with a 21 inch seat pitch or they'll rush to fill up a SF340 or Q400 at $29.

The miniscule number of the meek and irrationally afraid who won't fly on a turbo-prop is no larger than those who won't fly at all. They are meaningless as a segment of the air transportation market.

Companies are investing in turboprops, filling them up at lower cost and seeing high yields and margins.
