TriQ N8WQ climb performance


Jay Scheevel
 

Hi All,

 

I think I have enough flights to establish my DA service ceiling (16000’) at “average” operating weights.  I have yet to push my GW to the max of 1200 lb., but will get there eventually.  Here is my chart at Vy for your consideration.

 

Cheers,

Excellent. Next purchase a space suit?

No Jerry. I am putting in pressurization to 20 psi!  😊

 

Cheers,

That's not your service ceiling, it is your absolute ceiling. The service ceiling is just over 14,000 feet where you are still climbing at 100 fpm (the definition of service ceiling).

Service ceiling also needs to factor the density altitude(DA). Standard pressure/temperature is needed. At 14K this is 9F.
If a -20F cold day (we are winter now) then you will climb higher. Not possible in summer (+20F). 

Unless you are turbocharged, and even then the critical altitude of most turbos becomes a significant factor in the teens. However N/A engines are affected greatly by changes in DA.

That is why I plotted climb rate vs. density altitude. I have an EFIS that gives me a constant readout of density altitude.

 

Cheers,
Jay
