- This video discusses: Time & Descent Calculations (time, rate, distance), Glide Slope, Crossing Restrictions, and Rate of Descent (required during an approach, e.g. vertical speed required when established on an instrument approach). READ DETAILED DESCRIPTION BELOW:
By having two pieces of information, you can then deduce all of the other pieces of information by setting/finding the correct relationship almost instantly.
Minutes = Distance (in nautical miles) ÷ Speed Traveled (in nautical miles per minute)
Minutes = Altitude Change (in feet) ÷ Rate of Descent (in feet per minute)
Glide Slope = Rise (altitude change: in feet) ÷ Run (distance: in nautical miles)
Glide Slope = Rate of Descent (in feet per minute) ÷ Speed (in nautical miles per minute)
In “MINTES mode”, the outside bezel represents distance (either horizontal or vertical), while the inside bezel represents speed (either in nautical miles per minute, or feet per minute). Any value over the 10 placement will represent time (in minutes).
Accordingly, when set to “minutes mode”, the inside bezel can represent your speed being traveled (in the form of nautical miles per minute). In this setting, the outside bezel will then represent the distance (in nautical miles) you are away from something horizontally.
Furthermore, when set to “minutes mode”, the inside bezel can represent descent rate (in feet per minute). In this setting, the outside bezel will then represent the distance you are away from something vertically (e.g. altitude change).
When in “GLIDE SLOPE mode”, the outside bezel represents distance (vertical rise), or it can also represent rate of descent; while the inside bezel represents distance (horizontal), or it can represent rate of descent / vertical speed (in feet per minute).
Therefore, when set to “glide slope mode”, the inside bezel can represent the “run”, e.g. the distance you are away from something vertically. In this setting, the outside bezel represents the “rise”, e.g. the distance you are away from something horizontally.
Additionally, when set to “glide slope mode”, the inside bezel can represent the horizontal speed being traveled (groundspeed in nautical miles per minute). In this setting, the outside bezel then represents vertical speed (e.g. rate of descent) proportional to the glide slope that is se over the 10 placement.
Also, with the desired glide slope set up over the 10 placement, you can determine what altitude you should currently be at for any given distance, or vise versa, by simply noting the desired rise over run in comparison to your actual altitude or distance you are currently at. For example, for a 3˚ glide slope, you can find your distance (lets say 15 nautical miles away) and then quickly note the altitude you should be at (in this example, 4,500 feet).
Really good tutorial, keep up the good work. Sadly this is becoming a lost art. I am happy that some of us have not forgotten it. There is a a lot of substandard videos on this subject everywhere, but yours arguably the best. Keep up the good good work.
Joe G., The face is scratched being that I have worn this watch every day for over 5 years, that's over 1,800 days of tried and true abuse! This includes crawling under aircraft, mowing the lawn, hiking, you name it! The focus of the camera lens makes the watch face look worse than it is in reality because we are focusing at the glass level, not at the level of the watch hands. In person, the scratches aren't even close to being as bad as it seems in the video. Best watch ever. It's even solar powered!
Cheers
I don't know why you are mad. Regardless if he is a pilot or not (which he is), he still gave a very informative video.
it's a great watch. buy the sapphire crystal version :) amazing watch truly.
send it to Citizen and tell them you'd like a sapphire crystal installed it's around 80-100$! then make a video! YES, this is the best watch in the solar system
C Hobbs just glad to see you had true usage of this watch. This is an awesome watch.
as a pilot and aircraft owner ......i was lost !! not saying any of what you say is wrong...i just forgot all that some years ago. Good job though
Some of these methods are more practical for jet type flying (higher, faster). I know exactly what your talking about. If you're in a piston, the numbers are usually always the same OR you can just point at the airport and fly to it. Cheers!
Wore mine to Iraq. Messed it up after about 8 years and had to send it off go get a renovation. Came through on a test once when I forgot my flight computer. Gift from my beautiful wife. My favorite thing I wear.
This was an awesome tutorial, I have an aviators watch and I never knew what the dials were all about and after watching this video I'm still lost but that's just me, yet things are a bit clear as to why the dials are needed thanks!
exactly the sort of tutorial I was looking for. cheers !
@Keagan Juelz it took about 20 minutes but you replied to a comment about it posted 15 minutes ago...
I’m not a pilot, but I’m super envious and much respect to those of you on here who are.. I am a bit of a watch nut and am super interested in learning this.. I’ve watched the video a couple times… will it ever “click”? 😂 Just a tad confused. Mainly just the multiplication and division function, not so much the time of climb, etc….I’m pretty quick with math in my head, but just want to understand this gadget. Thanks a bunch for this video, tho!
Отличный туториал! respekt!
Holy cow! I wore that watch for 7 years and it was still beautiful. Curious what your daily routine is that your watch took such a beating...?
It’s prob not his, found it a dumpster and said. I’m a genius, let me shoot a video.
Very useful! Ive got the Seiko SSA 007 and your manual has helped heaps! Thanks!
Also great for calculating the tip at restaurants.
This Is One Wonderful Explanation. I Thank You Very Much.
Good post C Hobbs. Thanks for taking the time to make this video on a rather esoteric subject. I just got a Citizen watch with this slide rule, and was disappointed the owners manual didn't even mention it. I knew it was for calculating, but had no idea the scope of what could be done. Do you have any suggestions of where to get more information, and perhaps quizzes to make sure I am doing it right? I tried to follow along with mine, but the ruler is internal, and turned by a dial. The action is very slow to spin.
Thanks again!
I just bought a Citizen Blue Angels. Chuffed as anything to find I have an aviators' slide rule! But then I watch this and I realise that some pilots' watches, like the one shown, have free bezels you can spin round easily with your fingers! Mine is under the crystal, and can only be moved slowly, with the C button. Almost kills the whole point of having it, since you can practically do the calculations in your head before you can get the bezel moved round, to say nothing about having to have the right light conditions to read the thing.
Wow! Thank you for that really good explanation!
Very nice tutorial. Thank you so much for posting this. Cheers.
thanks and really appreciate your help..very very nice tutorial
awesome video! thank you for sharing it!
You can ship it over to citizen and have the mineral face replaced with a sapphire crystal. It only cost me $100. They also tuned the watch and replaced the bezel for free. I own a Rolex,Tissot and Citizen. The Citizen is definitely my favourite👍🏻
I have thought about sending it to get the glass replaced, maybe someday! I bought a second citizen instead!
Hey what is wrong with your crystal? is that moisture inside it or do you take an angle grinder to your watch face?
Pretty much. 5 years of wearing that thing every day. It's actually not that bad, it's the focus on the dial that makes the glass look like a gorilla wore it. If I focused on the hands you wouldn't have known, but we need to see the dial for the video. Cheers
This was a great tutorial
Thanks for watching!
Thank You Very Much! Awesome Tutorial.
Glad it's helping some people! Cheers
Woah! That citizen is messed up. 😂
Teaching requires much more than spinning a dial on a fancy watch! This guys RISE is giving me the RUNS! If this guy is YOUR CFI,,, GET ANOTHER INSTRUCTOR!
Can the bezel also be used to time things, such as with a dive watch bezel? I am aware that this isn't a dive watch, but though I do want a watch with a logarithmic bezel, I also use the timing function of my orange Orient Mako quite frequently. So I'm asking just to see whether this would be a good upgrade.
what model of this watch?
now that is a watch with some serious hours accumulated
Thanks so much
Heck yeah!
Where do I get the wrist band order or buying it online?
Damn, that poor thing needs a new sapphire crystal badly.
Can non aviators also watch this video or did I commit crime?
your watch is so beaten up that a lot of the number icriments are not visible
may it be a higher resolution video
I wish! Maybe I should re-do this video!
i do have a watch with an E6B but cant see the date let alone the scale those numbers are tiny eeeeny weenie tiny lol
It's even worse at night! When I'm forced to use it or want to play around with calculations, I'd have to take the watch off, or look like a nerd holding my arm two inches from my face. lol! It's a fun tool but not perfect! Cheers
It would be easier for me to do the multiplication in my head
Honestly speaking , All of these calculations can be made in the head with accuracy upto 2 decimals and for those who can't do that, we have calculators. These watches made sense when there weren't flight computers, but with them, it makes these watches redundant. And for flight training, I'd prefer trust my head over a watch.
I personally like to use the watch for planning things out, rather than using it for the "OMG I don't know what to do right now, help me" approach. Thinking of these variables is a great way to spend your time while at cruise.
There are multiple benefits which you may have overlooked. People make mistakes when they are pressured, and I can tell you from experience, aviation can sometimes be a pressure cooker when you need to make calculated decisions quickly. The idea of this watch is that 1) it never fails, therefore, it's a great backup, and 2) it teaches you the relationships of time, speed, and distance and how they relate to aircraft altitude; so that one day you don't need the watch or a calculator.
I'll give you a scenario: You are 90 miles out at 33,000 feet, flying at 480 knots. Can you quickly (within 10 seconds) identify how fast you need to descend to get to your airport adequately, without taking out your phone to calculate? I would say, probably not. The benefit to the watch is that you can do MULTIPLE calculations at one time, quickly. Thus eliminating possible errors while efficiently finding a solution to just this one question.
Under that scenario, you can set up the rise over run on your watch, in which you then instantly receive up a glide slope value (366 ft per nautical mile / 3.6˚ glide slope in that scenario). You have then locked in your relationship to any airspeed you might be flying. Rounding up, you would need to descend at 3,000 ft per minute. Which took two separate equations and 5 different variables to come up with one answer. With the watch you twist the dial once, and find your answer.
What is great about this method is that if you slow down to say 250 knots (required below 10,000 feet) the watch will instantly tell you you now need to descend at 1,600 feet per minute (rounding up) to meet that 3.6˚ glide slope.
On a daily basis I do not usually use the watch, but it has served me well in the past, and I enjoy understanding the variables. Personally, it keeps me on top of my game and serves a purpose.
Ultimately, airline / charter / corporate pilots have computers (FMS - Flight Management System) to do this for us. The watch just adds a level of know how.
C Hobbs That's absolutely true. I agree that it makes one more connected and involved in the act. It is always reassuring that you have a dependable device in your wrist. In fact, wrist watches in general are being victims of smartphones, which is quiet sad. I haven't been to a flight school, but have interests toward timepieces. And being a person who uses calculators extensively on day to day basis, I have developed the ability to make certain calculation even without using the calculator, so I was under the impression that it would be mastered by Pilots as well. Thanks a lot for explaining with a practical example

" ... also known as [AN] E6B." Let's get some help on that grammar, son.
Harpo, yes you are correct! I don't appreciate the condescending remark, it's about as distasteful as my bad grammar. When I realized the grammar mistake myself, I didn't feel like re-recording the whole lesson just to correct it.
Are you a pilot? If so, have you ever tried reciting memory items while driving a car or doing a task? Sometimes when we are thinking hard or multitasking we make mistakes! Cheers
I don’t have time for this BS....
