Phenom 100 Performance
 

Hey guy's: My company just got a Phenom 100 and we're working on getting it on the 135 certificate. Right now we're trying to figure out the single engine performance issue. It's a Part 23 aircraft so it doesn't have FAA certified single engine data (to my knowledge). And was wondering what other operator's like Jetsuite were doing.

23.66 requires the airplane to have single engine performance computed somewhere. Doesn't mean it has to make part 25 performance numbers, but it has to be determined at the least.

23.67 also requires single engine performance that must be there.

I'm sure it's in there somewhere. What are you looking for exactly? I might not fully understand what you're looking for. What single engine performance "issue" are you trying to figure out?

The Citation Mustang is a Part 23 aircraft, but its OEI performance data is to Part 25 standards...you sure the Phenom doesn't have Part 25 data?

Also, I'd be more concerned about getting it stopped...there have been what, at least 2 accidents now due to "BRAKE FAIL"?

Thanks for the responses. I'm starting school tomorrow, so most of the info is second hand. But what I got from the first guy we sent through training had to do with obstacle clearance. What he said was that it does have single engine data that was approved by Brazil and JAA, but not FAA. I reviewed 23.66 & 67 and I could be wrong in my interpretation. But I got that it has to meet the climb gradient criteria set forth in the regs. But if you're flying a departure or even a escape route that required a non-standard climb, then those numbers are not published.

Sure they are...you just have to do some math. You'll have to convert rate of climb (published) and airspeed (into a ground speed) into some sort of gradient. The Part 25 climb numbers I've seen give me a percentage. The Part 23 numbers I've seen are always FPM at x-y-z weight and a-b-c altitude and d-e-f airspeed.

In the end, you're either going to make it or you aren't. Look at the top of the climb and look at your single engine performance for that altitude at your planned weight. If you don't have it, you don't have it. Jepp publishes the climb rate at given ground speed right on the DP.

Oh....and I'm uber jealous! I'd LOVE to get in one of those 100s. I'm a ***** for the light jets. Does it have an externally serviced lav or is that just the 300?

Hey Mini:
Thanks for the response. The 100 has the removable lav tank for servicing, so for emergency use only. It does seem like it's going to be a good aircraft, but just like any other airplane its got plenty of bugs and upgrades that need to be addressed.

Rubber cement + lid = "No, folks. No lav on board. But if you need to go, we can stop enroute for a 'comfort break'. Just let me know."

I like it. I'll forward this to the owner!

...or just have the FO do it. :D

You people service your own "lav" honeypots?

That's what a $20 to the line guy is for...
