I’m wanting to do a flight from Hong Kong to Toronto and I want to step climb along the way. Is there any advice to set it up because I put the step climb heights next to certain waypoints along the way and yet it doesn’t climb for me. Therefore I end up manually doing it and using more fuel.
VNAV is only available for descent at the moment. However, if you are willing to pay some money, the IF Assistant app can be programmed to automatically climb for you whilst you are away - do keep in mind that you are still responsible for separation, and that you run the risk of receiving violations.
If you want to learn more about step climbs, DeerCrusher made a fantastic guide which is now available in the Infinite Flight Flying Guide. Even if you use In-Flight Assistant to do the work for you, it’s a great source to learn about what’s actually happening and how to best optimize it. Additionally, you can vote for VNAV for climb/cruise in the feature request that I’ve linked down below.
