Evaluating the Falcon 50

[HMR]

Are you guys flying 50s with the 3D engines?? I cruise ours above 41 all the time and still do .80+ and true around 445 at FL450...

Wow! Care to share how you're getting that performance? What are you using for climb and cruise power settings?

Ours is a straight 50, no engine upgrade. We can only get good perf above 41 when it's cold.
Interesting, our #1 engine runs about 15 degrees hotter than the others too.
That IS cool about the flight plan to HI...We have a 900EX for that though

Ok here is my two cents for what its worth.. And I am by no means an expert, but here is how I fly the airplane.. Now obviously climb performance is based on ISA temps, so when the temps cooperate everything works out great...Now..I was taught by an old salty falcon capt that the more you "load" the wing up on a Falcon the better it performs.. Im sure alot of you already know that. I have had the oportunity to fly all the Falcons except the 2000. The most important tool that I think you can have in the cockpit as far as performance goes is the AOA... I never let the plane get off what I call the "step". If you can keep the AOA around 2.0 through 2.5 then the airplane will stay on step and will climb as high as you want it to, and accelerate quickly once you level off.. If it starts to get above 2.5-3.0 you have fallen off the "step" and your doing more harm than good.. I will usually hand fly the plane to about 10,000 then turn the autopilot on and climb with IAS set at 260 - 300kts depending on what I am trying to do. If you want the fuel performance then climb at 260 until .67 out of about FL330 climb at .72 and always watch the AOA... You can be at .72 mach and the AOA be higher than 2.5 which in my opinion is not good. I was told that the quicker you can engage the autopilot during a long climb (i.e.15,000 to FL360 or something like that) the better performace you will get in the long run.. At first I thought that was b.s., but if you have a good autopilot I think there is alot of truth to that now. You'd be suprised how much better the autopilot keeps things stabilized.. Constant pitch variations during a climb hinder performance.(JMO) Once again our airplane is a 3D engine airplane, and its not a collins avionics airplane.. It is one of the 13 that came from the factory with Honeywell / Sperry avionics.. Same EFIS and autopilot as the 900B, with just a few variations in the autopilot. I say that because our autopilot works very well in IAS and MACH hold. Some other autopilots chase it around. I assume most of you flight plan 3, 2, 2. Or maybe 3,2,1900 for your fuel burns.. Which is what I do to. But the plane seems to always do better than that.. Would you believe me if I told you that I flew yesterday out of LZU to MSY went straight to FL400 and only burned a little more than 2700lbs in a 1+25 hour flight. The flight is not normally that long but there was alot of weather around ATL area yesterday. Let me also add that I just kept it a .80 mach. To make a long story short. Try flying the AOA between 2.0 and 2.5 in the climb and see what happens.. If it works for you let me know... ONCE AGAIN IM AM NO EXPERT ON AERODYNAMICS OR FALCON 50s.. I just fly alot and I like to try different things. Let me also add that I always use the N1 charts from FSI for climb.. For cruise I usually just keep it .80 mach. And I always try to go as high as I can to save fuel.. Between FL360 and FL450 (depending on ISA) you may loose 15-20 kts true. To me thats not too bad. Just FYI a quick way to know what ISA is at your altitude is to double your altitude and subtract 15. (ex @FL350 ISA= -55) or just look at your FMS if it has that capability. Atleast thats what I have seen.. Thats my two cents... If you fly a 50EX then throw all this out the window, set the trottles to the little tick marks on the gauges and go like hell.

Isa

I always found it interesting that ISA is a constant -56.5 from FL370 up to FL510

Now if some one would just explain the concept of ISA to Ma Nature and convince her to stick to it life would oh so much easier.
