Hi,

 

has anyone bothered to compare the Phenom's performance against the real-world performance charts yet?

On my flights, I have the impression that she is a bit too slow at a given weight, altitude and fuel burn rate.

 

What do you think?

I would be surprised given the number of pilots that have crawled all over this thing...

ok, thanks.

Strange. After some flights at ISA conditions at a given gross weight and fuel burn rate as charted, I consistently get 10-20kts TAS less than what the respective chart entry would suggest.

 

I use the high-speed cruise performance table from here:

Now, this could easily be fixed with a slight tweak to the parasite drag parameter in the aircraft.cfg, but I am really wondering if I am the only one with a low-performer Phenom.

Given the fact that this is pilot material for actual flight planning and not sales material, I would expect the data in the charts to even be on the conservative side with the aircraft performing even slightly better under most circumstances.

 

Am I totally off here? Where is my mistake?

Are you burning more or less - flying faster or slower?
