REFLECTOR: Fuel Consumption Performance

[steve korney]

Hi Chuck...

I think it's 2 percent... Not 2 kts.... Per 1000 ft.

Hi, Tim,
 
Nice numbers but I was curiouos about the 
difference between your IAS and TAS.  If I understand it correctly, a 
rule of thumb is the IAS speed drops by 2 kts for each 1000 foot.  So, 
at 175 IAS +21 kts (10,500 x 2 kts/1000 = 21 kts) = 196kts TAS.  I 
understand this is just a rough rule of thumb, but that leaves 19 kts (215 - 196 
= 19)unaccounted for.  Was it that much of a non-standard day, or is my 
rule of thumb bad?

I have a XLRG   with Cont. 
  IO-550  370HP because of high compression pistons and duel electronic 
  ignition. I just flew sunday and was crusing at 10,500ft  at 215k true 
  175 indicated on 12.5 gal/hr. running  100degrees  LOP  
  2400RPM.    Tim Rhodenbaugh
