Aa77 Fdr Data Explained - Corrupt Data Theory Debunked (split From Aa77 Partial Decode Program), "Missing Seconds Theory" - Rest In Peace Options

Here is a chart of the post-09:15 NTSB Exhaust Gas Temperatures (EGT) for both engines:

For the post-09:15 time frame, the average L EGT was 491.486 deg_C and the avg. R EGT was 486.823 deg_C.

For the entire flight, the L EGT averaged 588.15 deg_C and the avg. R EGT was 583.98 deg_C. The maximum EGT for both engines was the final data point taken at 09:37:44.375 EDT (my time extrapolation for partial seconds from data sampling rates).

EDIT: It looks like the server is down right now, but here is where I uploaded that N1, N2, & N3 RPM chart for the same time frame IIRC:

Leaning the Air/Fuel mixture does actually reduce EGT... after you reach peak EGT, but it will increase EGT as you initially lean from full rich in order to reach a peak EGT.

Ummm, why are you mis-attributing that quote to me Airman Dave? The original quote is on another thread BTW, and it wasn't me that said it:

Best check your facts, there Jack.

The only time EGT starts to drop in temp is when you starve the engine of fuel. You'll only get a 10-20C drop in temp after the significant rise in temp/peak before the engine starts to quit.

Depending on manufacturer, 5-10C rich/lean side of peak is recommended for power/economy cruise.

The context in which the GL's used their theory is that EGT temps decrease as the mixture is leaned. This is not true and will never be true. You will never get a cooler temp from leaning the mixture than when you first started the lean.

Are you talking about jet engines? The pilot does not lean a jet engine.

Yes i know. It is used in the same context used by your GL friends Beachnut... (IMG:http://pilotsfor911truth.org/forum/style_emoticons/default/smile.gif)

Well that was a "sweet" setup above for ol' LTC "Beachy Jack" to walk into then (post #30). (IMG:http://pilotsfor911truth.org/forum/style_emoticons/default/wink.gif)

EDIT: I wonder if he's been "promoted" to U.S. Marshal now, too: (IMG:http://pilotsfor911truth.org/forum/style_emoticons/default/ohmy.gif)
