F4U-1 E6B settings
« on: December 06, 2004, 04:02:01 PM »
I got a question for HTC

at what alts are the manifold pressure and RPM settings listed for on the E6B?

my reasoning for asking is to follow, I was getting some speed at Alt data and decided to check the MP and RPM settings at each alt here they are:

25Kalt:
Emergency Power:51.5" MP   2750 RPM
Military Power:51.5" MP 2750 RPM
Normal Power:44" MP adjusted to  2550 RPM adjusted to
Max Cruise Power:33" MP actual   2150 RPM actual
Max Cruise Power:36" MP adjusted to 2250 RPM actual
(chart says 36" MP and 2150 RPM )

20K alt:
Emergency Power:57.5" MP   2750 RPM
Military Power:51.5" MP 2750 RPM
Normal Power:44" MP adjusted to  2550 RPM adjusted to
Max Cruise Power:33" MP actual   2150 RPM adjusted to
Max Cruise Power:36" MP adjusted to 2250 RPM actual
(chart says 36" MP and 2150 RPM )

15K alt:
Emergency Power:59.5" MP   2750 RPM
Military Power:53.5" MP 2750 RPM
Normal Power:44" MP adjusted to  2550 RPM adjusted to
Max Cruise Power:36" MP adjusted to   2150 RPM adjusted to

10K alt:
Emergency Power:58" MP   2750 RPM
Military Power:53.5" MP 2750 RPM
Normal Power:44" MP adjusted to  2550 RPM adjusted to
Max Cruise Power:36" MP adjusted to   2150 RPM adjusted to

5K alt:
Emergency Power:57.5" MP   2750 RPM
Military Power:49" MP 2750 RPM
Normal Power:44" MP actual  2550 RPM adjusted to
Max Cruise Power:31.5" MP actual   2150 RPM

0K alt: ( Sea Level 20 ft )
Emergency Power:57.5" MP   2750 RPM
Military Power:49" MP 2750 RPM
Normal Power:44" MP actual  2550 RPM adjusted to
Max Cruise Power:31.5" MP actual   2150 RPM  adjusted to

what I found was at Sea Level, 5k alt,10k alt, 15k alt, 20K alt and 25K alt I was unable to obtain the settings listed on the E6B ( some were obtainable but not all, depending on the alt I was at )

is this a bug or is there an explanation? also above 25K Wep has little to no effect on the power or speed
