You don't know the definition of circular logic.... It is an appeal to authority... READ THE FACTS I PRESENT... Argue against that. Done.

WRONG WRONG WRONG WRONG WRONG WRONG.... No you missed the point, badly. Do the math..... Your eye is about 3 feet give or take from the AI. The DOT on the airplane reference is about 1/8" from the AI moving horizon card. Now compare seated position of a short pilot to tall pilot. Assume eye...

Ha ha yet you added. What does Parallax have to do with anything? Lets use scientific method, repeatable experiments, observation, data and mathematics (with a closed form solution) Parallax is not present in the display of "glass" which are CRT (yes CRT) to LCD. True. There could be off angle...

What critical phase? It is is all critical... Intuitive? What are you talking about. Whose intuition? What is your intuition about what? You are missing my point. You are in level flight most of the flight (C152, C172) and in the terminal area during IAP, or in shallow descents at cruise speed...

What misconception? Be spacific. Parallax and "legacy" instruments is off topic and irrelevant. Showing pictures cut from internet of advanced HUD (STC'ed or certified to a specific aircraft) is also irrelevant and off topic, although they pretty. pictures. Let's thread drift to FLIR, forward...

I am going to regret answering this dead thread BUT your logic is convoluted with "WHY?" We all agree that pitch indication will vary throughout a flight, with power, airspeed, altitude, aircraft weight, phase of flight (climb, level, descent). WHY? I answered this 10 times above, yet you ask...

Great question. Ask the FAA. Here is a good history from Wiki on EFIS: https://en.wikipedia.org/wiki/Glass_cockpit#:~:text=By%20the%20end%20of%20the%20century%20glass%20cockpits%20began%20appearing,standard%20on%20all%20Cirrus%20aircraft. Since Military and Part 25 planes (transport aircraft)...

Yea I have been flying glass cockpits for +30 years. Yet I still like my C152 IFR trainer I teach students in to be SOMEWHERE in the ball park of indicating level in level flight, Then your little petulant snip below is noted. Don't care, yawn. We are NOT adopting to the pitch being way above...

Ha ha "flight physics". Oh my gosh. No kidding. Who knew? Oh everyone. Ha ha. I do know aerodynamics or flight dynamics, as well as math, science and physics, ATP flown over 40 planes both GA and Airline, graduate degree in mechanical engineering, I got this chemgeek and can derive the lift...

Did I say that? What is a GI275? Google says MFD. OK. I have G5's. I can't keep up with every variation of avionics. Other GA aircraft I fly Aspen, Dynon, Grand Rapids, I can't keep up. Frankly I like flying my partners J3 with no glass and Nav by pilotage and dead reckoning.

Yes it is OK to close a thread, especially when you all are SO FAR OFF TOPIC. This is the AVIONICS area of forum not how to fly Instruments. In fact some forums allow the OP to close a thread. I would do it with this thread. READ my first post. NO ONE IS ASKING CAN YOU FLY WITH AI READING 3...

Clearly you did not read the thread or understand the point of the thread. Everyone knows. However we fly little planes by pitch not Angle of Attack (AOA). I and 99% of pilots adjust AI's to zero pitch REF in level cruise flight (AI's that can be adjusted). Do you not know this? Now we have...

Wow way to go. Kind of troll-ish bradg13, and disrespectful. You don't know how to send a PM? Really unless you know what you are doing and IT IS YOUR AIRCRAFT, don't mess with it. This could mask serious installation or hardware (AHRS) issues. You do what you want on your personal airplane...

Well the AI (vacuum or electro mechanical) had ability to adjust, at least with GA. The Reg for EFI is the aircraft pitch reference is not PILOT adjustable, or at least not easily adjustable. Garmin realized this is not really a benefit or what pilots want, so in their non Cert G5's for the...

NOPE it does not say FOR CERTIFIED INSTALLS, IT CANNOT BE ADJUSTED... NO WHERE DOES IT SAY THAT... You are wrong. You were off to a good start. What you may be confused with is per REGS the PILOT can not adjust it from the menu. You have to go into CONFIG mode, which was not intended to be...

Ha ha. I know what Attitude Inst Flying is, OK, but why not have it read level in (nominal normal level flight at cruise speed)? Second if the G5's in the plane I was teaching was as close as yours NO PROBLEM... It is 3 degrees nose up. That is ridiculous. There is NO REASON to "get use to it"...

The thing I dislike, is drift. Sir I did not ask for a lecture about SCAN- CROSS CHECK - INTERPRET - CONTROL. I want LEVEL FLIGHT to READ LEVEL.... not 3 degee nose up. I don't care what you think about my preference based on my experience, 14k hours, 10% of that dual given in all GA ratings...

Thank you. Note "In flight level cruse attitude is not necessarily the same as the leveling points provided by the manufacture. Adjustments to the pitch and roll offsets can be made to compensate for the aircraft flight characteristics." Garmin told me the same thing, and it does not violate the...

FYI I have done my research but want to get feedback from people who have zeroed out pitch attitude in flight. This is a club plane. It is in hanger for annual, which I am teaching Instrument students. I asked our club maintenance, A&P / AI to adjust it so it reads level in cruise not 3 degrees...

This is a great forum but there is a pattern I see of argumentative thread drifts. The ORIGINAL QUESTION WAS ASKED AND ANSWERED. No further comments are needed. This topic is closed. Thanks. MauleSkinner: Your original comment was great. Thanks for confirming. i also confirmed with DPE who will...
