Introduction to SimBrief


SimBrief ( is a free website that you can sign up for that lets you plan for your flights. It can give you a number of advanced data elements such as altitude, fuel, speed, and top of descent (TOD). I was working on a video for all of this but I think it was better to type it up.

  1. First, create a profile on SimBrief. You do need a valid email address for this to happen. Don’t worry once you sign up they do not send you spam mail.

  2. Once logged in, go to the dispatch system.

  3. Select “Create a New Flight”

  4. Start to fill everything out.

    • Airline - The abbreviation of the airline
    • Flight No - Flight Number
    • Depart - Your departure airport
    • Arrive - Your arrival airport
    • Alternate - It will give fuel to make it to this airport as an alternative. I usually do NONE unless needed.
    • Zulu - Departure time if you choose to use it.
    • Airframe - Select your aircraft.
    • Airframe More Options If you choose “More Options” You will see your “Climb Profile”. This is your speed while climbing. 250kts up to 10k, then 300kts transitioning to m.78 cruise. The same is listed for descent profile.
    • Below that are optional entries such as departure and arrival runway. I advise you to set at least the departure runway as it will get you on the SID for that runway.
    • Taxi Out/In - I usually change the Taxi Out and In to 5 minutes since the SIM is a little quicker than real life.
    • Altitude - You can leave this auto for long hauls. Short hauls from DFW to SAT I usually do FL260 so it doesnt send me up to FL330. Thats what is more flown in real life in my experience.
  5. After setting your Departure and Arrival aiprorts, the route will show at the bottom. You can change the route by selecting different routes on the right that are reflected in the map below.
    Advanced Users Advanced users can use this time to pull up departure and arrival plates and enter additional waypoints as needed. It will help to make your plan more accurate.

  6. Click on “Analyze Route”

  7. The top right of the screen is a section that I like to clean up. I uncheck everything but detailed navlog and change the units to LBS to match my setting in IF.

  8. You can copy the string from the route into your IF plan. Note that some may not exist, or some may be on the other side of the world, you will have to manually adjust those if needed.

  9. If you are happy with your settings, click on GENERATE OFP at the top to generate your plan.

  10. There is a summary section at the top that will give you information about your flight.

    One of the interesting pieces in there is your Block Fuel that you can use to fill up your tanks in IF.
    11.If you scroll down you will see your detailed flight plan. This can also be saved as a PDF.

    Yellow is your summary and fuel. Orange is your final fuel amount.

  11. If you continue scrolling you will come to your waypoints. Lets start with what everything is. There is a great interactive help button above it that will show you what each field is.

  12. The T O C listed is Top of Climb. You can use this information to give you a rough estimate on your climbing VS. Remember you are trying to save fuel so do not go crazy.

    The TOC is at 37,000, Dallas is at 270’. It says we should take 26 minutes to get there. 37000-270=36730. Take that divided by 26 minutes and you get 36730/26=1412. Round up for good measure, VS of 1500 if you want. I am sure there are better ways of doing it but this is just something quick and dirty with less math.

  13. The T O D listed is Top of Descent or “When you should start descending”. This is all with the assumption that you are following the listed speed guidelines in your plan. We can do the same math here too.

    90 miles out is when we should start descending. I usually add a about 10 miles to be safe. 1:34-1:16 = 18 min to go (37,000-3000) = 34,000 / 18 min = 1888 VS. Again, its not perfect but better than nothing.
    **Keep in mind that some plans will have additional waypoints after the TOD so you can use that to help gauge your altitude.

That is my quick and dirty guide to simbrief. It takes time to get used to all the information but you can choose to use as little or as much of the information that you can.

Wow, very nice tutorial Chris!
I’m sure it will help a lot of people doing more and more realistic flights in the future. :)


Great tutorial Chris - a useful simbrief tip I’ve found is if you set the OFP type to JetBlue it will calculate V-speeds for you which are very useful


Perfect maths wise, but simbrief does not take SID/ATC climb restrictions into account, so depending on your realism level your mileage may vary.


Yeah something is better than nothing. Some of their climb and descents seem way too short.


Wow, Chris. This is awesome stuff… I didn’t know how to use it yet either, so thanks!


Is thier a slightly simpler way to plan routes for us beginners? It was alot easier before the update so its kinda shocking.


The beginner way is to:

  1. Go to
  2. Search for your start and end airport.
  3. In the list of flights, pick one that has landed.
  4. In the right, you will see the flight details. You can see the route in there. Click on DECODE to see detailed waypoints.


Make sure you put in custom air frames with all the IF specifications. The weights for most of the aircraft in IF differ from what you would get in Simbrief. For instance, the OEW (Operating Empty Weight) in Simbrief for the E170 is actually less than in IF, so Simbrief will be calculating less fuel than you will actually need.This was validated by a Beta that it does make a difference. In addition, the most important weight factor you will input into the Simbrief system will be your ZFW, Zero Fuel Weight. Best to fill up your aircraft with pax and cargo first and find what your ZFW is on IF then input it into Simbrief to get a far more accurate Block Fuel read out.


Looks alot easier! Thanks


Chris, this is a much-needed and excellent tutorial! Thanks!


This is the kind of threads that truly stand out. Thanks for setting it up, sir!


Amazing tutorial! Really helped me out with SimBrief! I didn’t know how to use it till now, just like Tyler. Thanks!


Amazing tutorial Chris! This should hopefully help a lot of folks out.

I figured I’d drop this in here since it covers your reply exactly.


Thanks I added it to the main post


Hmm I’m sure I have seen some of those before… 😉


Really good job. I only used simbrief for fuel, but now I can use it for calculating my TOC and TOD


Nice one. Now registered with Simbrief.

Very clear and concise explanation of all the info.


Used your Tutorial to plan my EGLL–SFO long haul.
Worked perfectly, most notably the fuel block calculation.

I had enough in the tank in case I diverted to another airport, put in holding pattern (etc.), but instead I landed with <9% fuel left. Started with 190,000 lbs of fuel !!

Well done.
