Follow up to monster thread below re IAS and TAS and power required...
"BDS" wrote in message t... 6000 ft 75% power (2400 rpm/32-in mp/26.3 gph) IAS 157 kts TAS 170 kts 16000 ft 75% power (2400 rpm/29.4-in mp/26.3 gph) IAS 148 kts TAS 187 kts How come those are both 75% power? The high-altitude one seems like a richer mixture, less power.

The high-altitude one seems like a richer mixture, less power. Less back pressure at altitude, less MP required for the same %power. Note the fuel burn is the same. Al G
