- On the Private Pilot Checkride, you'll be asked to make a diversion from your planned cross country flight to a nearby airport. Here at the steps involved in making a safe diversion.

Great video as always. One thing that really helped during my PPL is to know my airplane numbers. For a diversion, you must be able to calculate Distance, Time, and Fuel without having to think too hard.
- Distance between 2 points on a map is easy to find, use your fingers and a reference for scale.
- Time: If you know your aircraft, you should know how many minutes it takes to fly 10 NM. Use that reference to quickly calculate your diversion time. Leave your E6B in your bag, you have an airplane to fly.
Fuel: If you know your aircraft, you should know how much fuel you burn in 10 minutes. Use that number to quickly estimate the fuel need to your diversion airport. Round up numbers to keep it simple.
Example in a Cessna 172:
- Cruise speed: Approx. 120 knot or 20 NM every 10 minutes.
- Fuel burn: Approx. 12 Gal/hour or 2 Galon every 10 minutes.
If you remember these numbers, you can very quickly estimate if you can make it to your diversion airport. If you want to be a bit more precise, use the ground speed on your GPS and apply a correction factor. Example: GPS shows 100 knot ground speed? Simply add 20% to your time and fuel burn.
Quick tip for people about to take their checkride: don't try to be specific with things like estimated fuel burn, distance, etc. Mark out 5nm lines on a pencil or whatever you use to write, ballpark the distance, and take a good guess at fuel. My DPE got pissed when I started trying to do the math for fuel burn; thats not what they're looking for.
Very good point, Biggie. Scenarios about being exact and covering every possibility are not realistic. The instructor and DPE should consider how we actually divert in real life. I agree with that being done without all modern aids. No electricity is realistic and once pilotage skills are shown, all aids can be brought into play. GPS should not deter us from using the sectional and identifying checkpoints. It is more interesting that way.
I like the way of learning how to estimate in simple terms.
A number of comments. First, I have not even held an E6B since the early 1990's. Second, precise estimates/measurements are only necessary if you are fairly low on fuel or at minimum fuel. Third, the reason we are diverting is not due to an emergency we are experiencing. Fourth: How much fuel (time) do I have. If three hours, then I may want to go somewhere not even close to the closed airport/runway. Fifth, you can determine approximate distance by use of your two fingers divider. Hold two fingers from one hand, one on your location, the other at your potential destination to get the distance. Hold that separation and hold them up to a vertical longitude line on your sectional to see how many minutes of latitude (NMs) that finger spread represents. Sixth, if distance is approximately 30 NM, wind is relatively low, and you have 1 hour of fuel, and the weather is good at the potential diversion airport, you are gold. Seventh, when I am flying, I constantly keep track of gallons and time of fuel remaining. Then if a diversion is needed, I already have the approximate radius of action/diversion defined, and I can spend more time deciding what airport to go to (maybe one with a really good $100 hamburger - with current inflation a $128 hamburger).
Also, you want your head out of the cockpit as much as possible looking for conflicting traffic. Don't over complicate the diversion for such a simple problem/exercise.
One other point. I fly with two certified panel mounted WAAS GPSs, and generally also Foreflight on an iPad, and then a portable Garmin 796 on my yoke. Not everybody can do this, but probably any pilot can fly with one iPad or tablet with Foreflight, Garmin Pilot, or another moving map GPS navigator.
Thank you for preparing and updating this video.
LOVE IT! so simple, easy to understand, and beautiful/helpful visuals!
Awesome explanations!! Here some fun: And then the specific winds in the Gorge will throw out all that original math! 😆 Not to mention the awful bumps you’ll be hitting, making you slow way down. The Dalles airport is on a really beautiful spot, too. Funny, it’s in a different state from the city of The Dalles (WA vs OR). Would make for a good spot to hang out for a bit, though. Lots of resources to help bide time til the original airport opens up.
Thank you so much this is a real exercise happening in real life not just a lesson on the board excellent thank you
Very nice divert vid! Thank you!!
Perfectly done!
Great video. Thanks
Very nice tutorial. I'd add that you should make a wind card based on the winds aloft you used for cruise. This gives your GS and WCA for every 45 degrees. That way you don't have to fumble with the E6B to approximate it.
very helpful, thank you!
The was rushed in the end 😂. Great tutorial as always.
Magnificent
I kept thinking you were saying “Dells”, airport KDLL and VOR identifier DLL. It’s a popular water park destination just a short flight away from me.
Have you ever heard of the windprotractor? Look it up, it is a lot easier and faster then the E6-B.
I like the approximate. Be a bit clumsy trying to plot the distance. Maybe a quick cheat way with your hand on the map if you have no VOR or other landmark to help with approx distance. I do not think it would be steady enough to try and plot on forflight. This is going to take some practice
With your point about using the VOR as a tool to get to the alternate, would it also be a good idea add Nav NOTAMS to your pre-flight brief? That shows it any VOR’s or other Navaids around your route are out of service.
One thing I might add, when I took my private My DPE was actually upset that I didn’t pick up flight following. If it’s available just pick it up.
I wondered about this. My checkride is may 5th. Do you actually need to get flight following if you're going to divert anyway? I don't see the point of that. If that is the case do you just cancel FF right before you start diversion calculations or what?
@@DaBladePwnI would think in real life, flight following would be helpful to lighten your workload and asking for assistance as needed. It’s like having a lifeline. But that’s real world. For simulated scenarios I would just verbalize?
240 degrees was a guess. How about using the compass rose and using flat edge from a plotter?
I've seen other diversion vids have the PIC circle (before diverting) to determine course, distance, fuel burn, ETA, etc. Which is correct? Great instructional vids btw!
makes a negligible difference if you work quickly
I was told if it’s an urgent reason (such as a medical emergency scenario during your checkride) then don’t circle but turn to an estimated heading sooner rather than later.
Since these are VFR tutorials please use the online feature of MSFS, that should improve the videos.
Great video!!!
Are you from eastern wa?
Good video however, with all the technology we use today, this is not practical at all and should be updated by FAA. I do not know anyone that uses an EB6 and actual chart since they got their PPL. This method would be the same as taking a typing text and using actual whiteout versus a 'delete' or 'back' button.
You're not wrong, wrong, but I think its absoutely practical to know some old ways for some things.
Flying can be a pretty lethal affair, so why not have some low tech fallback? Not THAT much to think about in the grand scheme of things.
And consider the internet, many people use discord, when discord goes down, countless people are out of a communication option.
I use discord too, but I also have my own IRC (caveman tech) server running my best internet friends (and some of my reallife ones) know about.
And yes, that can fail too, but it's still a decent backup.
9:50 those ridges on the river make flying into The Dalles fun: czcams.com/video/HPrRYIUoVik/video.html
and thanks for the diversion vid! added to my "review again before checkride" list :)
I doubt the DPE would allow ForeFlight.
You'd be correct, I failed my diversion task during my check ride because although I had a G3X and a G430, as well as my iPad and phone for foreflight, I was given a doomsday scenario where all 4 are not functioning so I needed a paper sectional which I did not have
I missed something…. Why 3 x 7?
You need to lose 7000 feet to get to pattern altitude, multiply that by three to get how far out to descend
I find it unsettling if I heard you correctly that an individual examiner can decide whether you can use gps or not. Shouldnt that be standardized?
Can you do boeing tutorial please?????
Go to nearest airport …
This is a robotic explanation, not real life related, nobody has time to hold an old esb my guy
lol What are you on about? His fuel tanks were full. He could have stayed up for 4 hours..
