Why is this needed?
I’ll explain with reference to the picture above. As you can see from the graph, the step climbs from one altitude to another with 2000ft intervals takes place over a long period of time which last for a few hours. In fact, you can’t really notice an increase as it’s very gradual. This is because the aircraft is climbing below 100fpm which is currently impossible in IF using A/P. IF should enable pilots to step climb on A/P with the V/S button being able to select climb rates below 100fpm for realism. I know this can be done manually and thereafter hold V/S but you would need to calibrate it many times and you’ll probably need to put your device on something sturdy for stability. So please don’t comment saying that this can be done manually and that this thread is meaningless
The picture above shows a faster climb rate which is what IF allows currently. Although this feature could be of lesser priority (at least we can step climb with autopilot with 1000fpm) but it would be bonus if more gradual and slower step climbs are enabled with rates of below 100fpm.
