I am quite new to SD and I got a question about timers. I mainly fly two different aircraft, with different schemes how to switch fuel tanks. The first one, a DA40 requires to pump fuel from right to left after a certain amount of flying time, performing this for a few minutes. The second one, a PA28 requires simply fuel selector switching every 30min time. Is there an option to relate timers to aircrafts?
