Aircraft Avionics Basic Introduction

- Until recently, most General Aviation aircraft were equipped with individual instruments which were utilized collectively to safely operate and maneuver the aircraft.
Within the last 10 years, electronic flight displays made from LCD screens have begun to appear in nearly every new aircraft.
The first screen is installed in front of the left seat pilot position and is referred to as the primary flight display or PFD. The second screen, positioned approximately in the center of the instrument panel, is referred to as the multi-function display or MFD.
These two screens de-clutter instrument panels and increase safety. The increase in safety is due to the utilization of solid state instruments which have a failure rate far less than those of conventional analog instrumentation, and the display of more situational awareness data that was not previously available.
Whether an aircraft has analog or digital, commonly referred to as glass instruments, the instrumentation falls into three different categories: performance, control, and navigation.
Performance instruments indicate the aircraft’s actual performance. Performance instruments include the altimeter, airspeed indicator, vertical speed indicator or VSI, heading indicator, and turn-and-slip indicator.
The performance instruments directly reflect the current performance of the aircraft. For instance, the speed of the aircraft can be referenced on the airspeed indicator. The altitude can be referenced on the altimeter. The aircraft’s climb performance can be determined by referencing the VSI.
Control instruments display immediate attitude and power changes, and are calibrated to allow adjustments in precise increments.
The primary instrument for attitude display is the attitude indicator. The control instruments do not indicate aircraft speed or altitude. In order to determine these variable and others, a pilot must reference the performance instruments.
Navigation instruments indicate the position of the aircraft in relation to a selected navigation facility or navigational fix. This group of instruments includes various types of course indicators, range indicators, glideslope indicators, and bearing pointers.
Newer aircraft with more technologically advanced instrumentation provide blended information, giving the pilot more accurate positional information.
Navigation instruments are comprised of indicators that display Global Positioning System (GPS), VHF Omni-Range (VOR), Non-Directional Beacon (NDB), and instrument landing system (ILS) information.
They also provide pilotage information so the aircraft can be maneuvered to keep it on a predetermined path. The pilotage information can be in either two or three dimensions relative to the ground-based or space-based navigation information.
GPS is a satellite-based navigation system composed of a network of satellites placed into orbit by the United States Department of Defense (DOD).
GPS works in all weather conditions, anywhere in the world, 24 hours a day. A GPS receiver must be locked onto the signal of at least three satellites to calculate a two-dimensional position (latitude and longitude) and track movement. With four or more satellites in view, the receiver can determine the user’s three-dimensional position (latitude, longitude, and altitude).

Thank you!! Please continue
+Ivy S Thanks for watching!
Glad I found this. Thank you and can you please make more videos about avionics stuff?
Thank you for the Aviation videos. I’m an aspiring pilot and will be starting flight school
Great information, thanks.
Thank you for avionics information. I hope if I make effort in my college which could help me to be professional pilot in future. Happy to study this things.
Are you a pilot now it’s been 5 years
it was useful for me
please share the next videoes
thanks
Glad to see your back in the Video making business :)
Thanks Will!
+Daniel Blell Thank you! Many more to come
An awesome video would be what constitutes a IFR equipped aircraft, I know it has some of the instruments you mention here (glid slope tracers, VOR's WAAS GPS, that sort of thing) but I have never understood what qualifies an aircraft as "IFR certified" if I ever wanted to buy one legal for instrument rating
I came across thos WONDERFUL video and it made my day! THANK YOU!!!
One question: do airplanes have both, glass and analogic instruments or just the glass ones? If this is the case, what happens if there is a shortcut or something of the kind?
Should we protect pilot eye by using projector on screen display
What if there is an electrical problem and i turn off avionics? Maybe tge master switch too? Can one fly back home safely so you dont get stranded?
I'm sure someone must have already mentioned that you mislabeled the Atitude Indicator as the Altitude Indicator.
electronic vale avionic engineer bane sakte hh ki nahi
I intrested it
1.25 minutes attitude indicator is misspelled
You want a trophy ?
is this job stress free?
lee phan if you loved it then it’s a stress free kind of job
Impossible

Definitely watch at 1.5x speed.
❤️❤️❤️❤️😭😭😭🍻😭❤️❤️❤️❤️❤️❤️
What you highlight and what you talk about are rarely the same. It makes it extremely confusing to follow.
My smartphone,s, computers, and tablets crash about daily... the guages in my cars/trucks/motorcycles/tractors/etc... have never failed in 40 years...
Dont get me wrong, the computer is ok for night and for GPS visualization... but id only ever consider it an accessory to supplement analog instrumentation... I dont need a computer readout to fly, but I do need analog gauges... especially if the computer crashes...
If you think a single failure can cause an aircraft to lose indications, then honestly, you don't know anything about modern avionics systems.
@@rcairflr when the computer crashes its not a "single failure", you lose everything computerized by that computer, at the same time...
@@toadamine . What exactly computer?" There is not a single computer that runs the whole aircraft or even the cockpit. Many LRUs have a processor in them. For example. Each Display on a modern airlihner has its own processor. If it fails, the display will fial, but all the data will go on another display, many will do it automatically. If a Flight Computer fails, there are usually 3 on a modern airlineer and another will take over. It is called redundancy and that is why you hardly hear of major failures. So as I said earlier, a single failure does not cause loss of data to the pilots.
@@toadamine > you stated: " when the computer crashes its not a "single failure", you lose everything computerized by that computer,".
That statement shows that you really have no idea how a modern commercial airliner is designed and operates. I am out of here. You just make statements based on your lack of knowledge.
@@rcairflr there was just one-third other day I was watching where the computer kept telling the pilots the wrong info and the airliner crashed... was either on Montour or blancolirio, and it's not uncommon on these crash investigation channels to have a computer or computerized sensor fail or become corrupt and give bad info or whatever and cause major issues that the pilots have to go thru boots to troubleshoot while the plane falls out of the sky
Good info but booooring
