Setting up on the ground is an easy way to do this with your airplane securely restrained. Ideally we want to get 4 ATV set points to begin the tuning of your smoke pump to throttle program mix. The ATV points that we want to achieve and note are described as percentages of travel. The following ATV rate data points are required for setup: 1-WOT, 2-Minimum throttle setting with smoke ON, 3- Pump speed at WOT, 4- Pump speed at minimum throttle setting with smoke ON. For this setup test if you can set your pump ATV function on a rotary dial it will be simpler than switching between menus. (Depending on the make of your radio.) For the sake of discussion, the values in parentheses are ATV examples.
Once these points are known, these will be the limit points of your pump curve setup. Setup a PMIX program where the smoke pump input is slaved from the throttle and activated by a TX switch. Also note that the pump curve may not be linear and may need some tweaking based on your mechanical differential or throttle curve that you may have already set up for the throttle.
Smoke systems are accessory items and may void your engine warranty. Consult your engine manufacturer for specifics. BDS assumes no responsibilities for damages incurred due to improper installation or setup.
