Hello Michel,
That was at 8500 ft. Ruidoso airport elevation it 6814 ft and traffic
pattern altitude is 7900 ft and you have to clear some high ground to
get in. TAS was over 130 kts and ground speed was 145 kts with an
unusual wind out of the east.
Blue skies & tailwinds,

Hello Bob,
What altitude do you check
Le 09/09/2014 16:22, Robert Borger a =E9crit : 5000rpm and 30" 120 kt ?
Many thanks

get around to installing the wheel pants & gear leg fairings it will
probably be faster at the same fuel flow or I can cruise at the same
speed for a lower fuel flow.

I don=92t know how critical that may be.

particular aircraft. Then arrive at a nice economy cruise speed/fuel
burn and a regular cruise speed.

and this will vary with aircraft weight and differing aircraft. But at

groove.

just =91feels=92 right!! Find the sweet spot for YOUR aircraft and
cruise there=85.why would you do any other?!!
