Most aircraft should "tell" the pilots that the flaps are not out far enough when the pilots shove the throttles forward. (Assuming the bleeper is also working ) If the pilot tries to take off with say less-than-5-degrees ( the limit isnt certain bu I think 5 is the minimum it will allow for a take off ) of flaps and shoves the throttles forward past a magical angle where it can be safely assumed that the pilot wants to take off then the bleeper should go off which is a intermittent 'horn' . Physically , an aircraft can take off with no-flaps as long as you have plenty of runway and plenty of noise-tolerant people living near the airport. There are graphs used to figure these things out , which plot the power required against weight-of-aircraft / length-of-runway / slope-of-runway / flaps needed/wanted and a load of othe rothings.... if you can stick your pencil inside the "safe area" then your OK otherwise start losing cargo/fuel/passengers or wait for a stronger wind !
