Out of The Ashes: The New Black Phoenix Phenom 100E GTN-750 Mod

Recommended Posts

Part III

So the last feature I really wanted to highlight is one that for those who fly the Phenoms quite extensively, may be a little weird to get used to at first.  The Full Authority Digital Engine Controlled (FADEC) on the Phenoms really make engine operation and monitoring a simple task for the pilot.  The throttle modes on the other hand might be a little different to pilots not accustomed to flying Airbus's before jumping in the Phenoms 😄 In stock form there are 5 modes you can operate the Phenom engines in (6 if you include Idle).

  • Max Crz- Cruise power settings
  • Con/clb- Climb power settings
  • TOGA- Takeoff and Go around power settings
  • MAX-  Max N1 power settings
  • (Manual control)- Pilot input throttle control between Idle and Max Crz

For the most part Carenado modeled this okay.

The problem comes when you replace the stock engines with ones that can put out 200lb+ MORE static thrust (EACH). Suddenly you will find the power settings for these modes don't really line up with the power output of the engines.  Furthermore, the FADEC throttle modes on the Hondajet are slightly different

  • Idle
  • (Manual Control)- Pilot input throttle control
  • MCT-Maximum Continous Thrust
  • TO-Take off (similar to TOGA)

In this mod I've implemented a little of both

  • Idle
  • (Manual Control)
  • TO
  • CRZ
  • MCT

Like the Hondajet this is a manual centered system.  That means for the majority of the power range the Pilot will actually set the power settings.  With this much power and so many different environments the plane can be operated in, it only makes sense to let the pilot select how much power is needed based on what they observe the aircraft doing.........Its only in the upper 15 or so percent of the power range where the computers are more "involved."

PhoenixThrottle1_zpsith5gmeu.jpg

This means up to about 85.5% N1 the pilot controls how much thrust is needed.  After passing 85.5%  The system selects its first mode, TO (takeoff)  This mode ranges between 85.5% and 90.5%N1. As there is more than sufficient thrust for takeoffs on runways longer than 4000ft most pilots will resort to using TO mode more as a Flex Takeoff option especially in colder temps.

 

PhoenixThrottle2_zpsmhr5tmpy.jpg

For some, CRZ (cruise mode) may seem a little weird.  Takeoffs in the Phoenix are performed in either TO mode or MCT mode.  This means if a takeoff is performed in TO mode.  Thrust must then be increased (not reduced) to engage MCT mode which is also used as a climb mode.    From MCT mode, CRZ mode can then be engaged as expected by decreasing thrust.  It is important to note the Phoenix is more than capable of cruising with LESS than CRZ mode power settings and you may often find yourself pulling power back depending on the conditions to avoid overspeeding.  This only means she'll give you even more range 😎  CRZ mode falls between 90.5% and 95.5% N1

 

PhoenixThrottle3_zps6h4cvq4f.jpg

MCT mode will be the mode utilized most when setting automatic power (ie anything outside of manual mode; not to be confused with autothrottle).  Ranging from 95.5% to 100%N1  This will be the range most utilized for high performance takeoffs, max weight takeoffs, short field etc etc.  MCT is also the range utilized as climb mode.  For lighter weights the lower end of MCT will provide enough thrust to reach cruise altitude.  However, in most cases above 28000ft pilots will want to just climb at 100%N1 in order to maintain the 210/.55-.60 mach climb schedule.  At heavier weights, higher altitudes or fighting strong headwinds, MCT mode can also be used as Cruise mode (albeit with a much higher fuel burn).

 

MCT Enhance

MCT Enhance mode is an AUTOMATIC mode purely controlled by the system.  It cannot be engaged in anyway by the pilot.  With that being said, it does need pilot input to disengage it 😄

MCT Enhance is a performance mode only engaged to enhance the aircraft's hot/high performance.  The base Phenom 100 had a lot going for it, however it's hot high performance was one thing that was not.  The additional 400lbs of static thrust equated to approximately 400 lbs of additional carrying capacity. (MTOW is now 10,900lbs)  However, under certain conditions more power may be needed to get that additional weight airborne.  Lets go to Telluride.........................

 

Pheonix38_zpsitmeer60.jpg

I can't remember what date I used in ASN history mode, but this was a real day's weather in Telluride last summer.............

Pheonix38MCT_zpszk4o6mv6.jpg

Note that "todays" outside air temperature is 21 deg C or approximately 72 deg F....I have not set the barometric pressure in this pic yet.  If I had it would show 9070ft on the altitude reading.  For those not familiar Telluride (KTEX) airport which is located high in the Colorado mountains serves the city of Telluride (Imagine that).  It actually sits on a mesa and is known for its 7111ft runway with a nearly 35 foot slope and the extremely high terrain that surrounds it.  Performance is everything when flying into and out of this place!

 

Today we are departing and we have a very FULL load.....(10890 of the Phoenix's 10900LB MAX takeoff weight to be exact  😳)

Pheonix37_zpsveevphjz.jpg

Pheonix39_zpse3s4vqjm.jpg

Flaps set at 2, Hold the brakes, Throttles to the Firewall..................CAS lets you know you're getting the full beans for this departure!

Pheonix39MCT_zpsnoxzm9db.jpg

 

In the time it took you to set throttles to MCT, the system determined the outside temperature and altitude warranted max performance.  Upon the "MCT ENHANCE ON" message being displayed the FADEC automatically configures the Thrust bump function of the engines.  I won't tell you exactly how much additional static thrust Phoenix will give you on top of the 2050lbs each engine is already producing, but what I will tell you is in situations like this you will appreciate every little bit.  Even with MCT Enhance engaged at this altitude in these temps she starts rolling...........really slow....Yet some how the cliff at the end of the runway finds a way to get closer and closer REALLY FAST!!!  It is definitely a pucker factor of infinite proportions.............  💩 <~~~ clench the brown Grinch

Pheonix40_zpsrdxuzscb.jpg

Today the Honda Vtec won't be denied (car guys will get that)...She gets us airborne with about 800ft of usable runway left until the EMAS!  Having completed this takeoff I wouldn't try this in anything hotter than 80 deg F at MTOW here............

Pheonix41_zpsg5o3zqmj.jpg

The thing you have to remember about MCT Enhance is the PILOT MUST DISENGAGE IT meaning after NO MORE THAN TWO MINUTES....the throttles must be pulled back a bit. 

Pheonix42_zpsdnwbggyu.jpg

Once the "MCT ENHANCE ON" message disappears, the engines can be throttled back up to 100%N1.  Usually this can be done without reactivating MCT Enhance.  However, if operating out of hotter locations like Dubai you may see it reengage even after disengaging it after 2 minutes.  If it does reengage, the engines must immediately be throttled back to a setting that deactivates MCT Enhance but still maintains the needed performance.  Its a bit much but how else do you think we can maintain the HF120's 5000 hour TBO (Time Before Overhaul) rating? 😁

Now there is one exception to the two minute rule and this is if MCT Enhance activates when one engine is out during flight.

Before anyone asks the VC pedestal does not have the new throttle modes included (yet)......Can't seem to find ALL the textures needed to change it

 

Part IV (and the final part) will address the remaining features I've incorporated/improved and I'll let you know what other plans I have for the Phoenix.  I'll also key you in on some of the issues she still has (like the pedestal one I just mentioned).......Yes there are still some nagging ones to me 😭........Honestly most of you probably wouldn't even notice them LOL!  

So what do you guys think???

PART IV

Sorry I've been MIA for so long.  The life of an engineering student is one of little free time.....#FACTS 😁 So this last part won't be nearly as long as the first three at least I hope it won't be LOL......  Like the real bird the brakes on the Carenado Phenom 100 can get kind of squirrelly especially on landing.  The real bird was one of the first business jets to incorporate electronic brakes.  Think of fly by wire just for your brakes.  Early on this caused many accidents because pilots who were used to manual hydraulic brakes would start pumping the brakes during their landing rolls.  They would quickly find that they suddenly lost all brake effectiveness, would pump more, still not slow down, freak out and assume the brakes failed, thus causing them to pull the emergency brake handle which would lock up the mains and subsequently deflate the tires.  Why would they pump the brakes you ask?  Simple, like fly by wire the electronic brakes give no physical "feel" like real brakes do.  Embraer tried to remedy this by incorporating different tensile springs attached to the brake pedals to simulate this feel but they had little success.  To compound the problem the system itself early on wasn't that reliable as it wasn't uncommon for brake sensor failures to occur during the landing sequence.  Again this would lead to pulled emergency brakes deflated tires, aircraft sliding off runways etc.  

photo.jpg

Read about the accident in this Picture HERE

"So Novej what was it about pumping the brakes that caused these accidents?"  Well I'm glad you asked.  It turns out Embraer programmed the brakes kind of like an on off switch.  Once they were applied during a landing sequence the pilot would have to maintain even pressure pressing the brake pedals through out rollout.  The system would apply the brakes in a linear fashion from a minimum pressure to a maximum until max brake effectiveness was achieved.  The problem is, if the pilot let off that pressure even for a fraction of a second, the system automatically reset to the minimum pressure which meant everytime he continued to pump them, he would continue to reset the system to minimum brake effectiveness.  Combine this with pilots failure to maintain incorrect landing speeds and it's easy to see where the problems would come in (they often landed too fast). Embraer is on like their 9th software revision of this system and many pilots still hate it (one of the few negatives real world pilots will tell you about an otherwise outstanding airplane)

Carenados P100 brakes can cause quite a few issues too.  I won't go into all of them but what I will say is I think I've drastically improved them.  First the majority of the problem came from two high a toe pressure brake setting and too high a differential braking effectiveness setting.  I've turned down the former and completely turned off the later.  Furthermore unlike the real aircraft and Carenado's version, the Phoenix requires the use of the Yaw damper all the way through the landing rollout.  Previously it would be disconnected on final approach.  Also don't forget the Phoenix now has spoilers too which are pilot activated on landing which can further help in the stopping program!.

"But Novej what about those of us who use differential braking to help steer???"  Don't you worry.  I've addressed that too.

Pheonix45_zpsyxaxe717.jpg

That Nose wheel steering though 😳

Pheonix46_zps1zmf3yk2.jpg

Pheonix47_zpsfpirdklc.jpg

You now have 70 degrees of nose wheel steering.  To put this in to perspective, this means the Phoenix can turn 180 degrees in nearly the width of its own wingspan!

Between the brake upgrades and steering changes I have found the Phoenix to be vastly easier to control on the ground.

SHE SEEMS PERFECT WHAT'S LEFT (RELEASE IT ALREADY)!!!!

Well not so fast there are still some nagging issues that I'd rather honestly fix before release, but I know the majority of you would not mind if I didn't.  The problem is as I've learned with the CJ2+ once the number of requests for the aircraft is in the hundreds its hard to push any later updates to everyone.  Not impossible, just hard....

Some of the issues include:

  • (If you scroll up and look at the Primary Flight Displays (PFD)  You will see these first two points.) First the trim display looks fine.  The problem is, it's backwards.  That means as you trim UP the numbers it displays goes DOWN and vice versa. 
  • There is a nagging yellow TERRAIN warning displayed on the PFDs which is a bi product of the update Carenado did to allow the aircraft to be ready for their synthetic vision program
  • By programming the "invisible" spoilers to a two way VC switch there is no ARMING function.  This means the pilot must remember to activate the spoilers upon landing, a function the 100E and 100EV do automatically 
  • I'm sure there's more I can't think of right now......

Then there's the additional features that I'd like to add but haven't had time to yet.....For instance just like my CJ2+ mod I want to add all the aircraft checklists to the GTN!  I'd also like to create a display on the MFD which shows real time aircraft gross weight.  This would help with landing and takeoff speed calculations tremendously as you would not have to leave the sim to pull up the payload menu to see what it is....

Like I've said numerous times we won't even get into how much work it will requir to package all these changes up in a way that wouldn't effect your base model Carenado Phenom 100s.......

Anyways that's it everyone! This is my Black Phoenix Phenom 100E GTN750, mod.  For all my CJ2+ fans this is the reason why you all haven't got an update in a REALLY long time.  However, I am proud to say even on this very day (LITERALLY) I'm still getting request for her! 

 

If I do release the Phoenix's I only hope they can generate just as much hype!  Thanks to everyone who have commented so far, and all who have read this entirely too long thread.  So like I always end these, tell me what you guys think!? 👀

I can't wait! This all sounds too good to be true. I fly the Carenado Phenom 100 regularly and love it, but everything you talk about as a shortfall is so true and bothers me. I fly RW out of KMLB (Melbourne, FL) where the US Embraer Phenom production line is. I've toured the plant and love that airplane.

Wow @Novej757 !

Incredible. I'd like to ask one thing which may possibly be slightly left field. Presently with the Navigraph extension pack, one can't import flight plans. There wouldn't be anyway to easily fix that glaring hole would there please?

I get it if not but just thought I'd ask, as its so fundamental, I'm seriously considering migrating to  A N Other plane which would be sad.

Thanks a lot.

Just wondering Novej757, Which GTN750s have you implemented,  Flight1 or RXP? and

Where can I get the repaint from? 😄

I could have sworn I answered this question here.........just noticed that I hadn't.  Maybe I started and never finished......Anyways I use the Flight1 GTN.  However, there are some users that have confirmed the RXP works with the CJ2 mod too.  I can't believe I forgot to include the reference to the original paint.  This livery is a custom version of HB-VRV done by Pascal Kuffer (available in the Avsim library).

If released it will be pretty expensive. I'm looking at selling it for $FREE.99. However, I will offer a discount of 99 cents off...As far as a manual....you already have one just read this thread 😉
