AI Thread Summary
An MHRS (magnetic reference heading system) is not the same as a traditional heading system, though they share similarities. An MHRS typically includes components like a heading indicator, slaving control compensator unit, flux gate, and directional gyroscope, which collectively provide accurate heading information relative to magnetic north. The advantages of an MHRS include reduced errors from dip and acceleration, as well as less susceptibility to deviation errors, making it more comprehensive than a standalone compass. However, it also has disadvantages, such as higher costs, increased complexity, and potential for gyroscopic errors. Understanding these systems is crucial for pilots and engineers working with integrated flight instruments.

Is an MHRS the same as a heading system??

I have to answer a question regarding an MHRS (magnetic reference heading system). I can't find much information online at all, though i have blindly stumbled onto heading indicators which rely on flux gates as well as a directional gyroscope.

Am I reading about the correct thing, or am I way off?

As far as I can tell, a heading system is made up of four component parts,

HSI
Slaving control compensator unit
flux gate
Directional Gyro

It is used to provide the pilot with heading information with a reference to magnetic north and its advantages/ disadvantages over a stand alone compass are as follows:


Advantages

• Does not suffer from dip error.
• Does not suffer from accelerating error.
• Less susceptible to deviation error.
• Able to provide more information/ more comprehensive system.



Disadvantages

• Cost.
• More components, more prone to a system failure.
• Subject to gyroscopic errors.
• Can ‘topple’ during abnormal flying conditions.



Please excuse my naivety, I am an electrical engineer but have to complete an integrated flight instruments to gain all of my modules.


Regards

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
