12-06-2021, 01:36 PM #1Phenom 100 Envelope Expansion
Great news for Phenom 100 pilots. The 100 has always had the most restrictive temp limit at altitude of any jet I've flown: -60C. Next closest is -70C, so huge impact at times.
AFM Revision 27 was just released with an expanded envelope:
There are some minimum mach numbers associated with region 2, but for normal ops when it's just a couple degrees cooler than -60 it should be easy to comply. -

(Username Protected) flies a P100EV- it looks like they have an extra two degrees, likely because of their ability to make more thrust at altitude makes the higher Mach possible.
Here is speed table from P100 AFM:

12-15-2021, 11:21 AM #6ForeFlight users: Phenom 100 STD and ENH flight planning models have been updated with the expanded temperature envelope and all-new data from the in-flight performance software to match the latest revision. I still have the EV to work through, probably next week though.
