Following diagram represents ___________(a) typical speed limit chart

1.	Following diagram represents ___________(a) typical speed limit chart of propulsion system(b) drag polar(c) lift curve slope(d) lift coefficient variationI have been asked this question in an international level competition.My enquiry is from Propulsion Selection topic in portion Propulsion and Fuel System Integration of Aircraft Design
Answer» The correct option is (a) typical speed limit chart of PROPULSION system To explain I would say: Above diagram is used to show the typical speed limit chart of current propulsion system in aviation. As shown TURBOPROP and piston PROP cannot be used for speeds beyond Mach 1. Lift curve SLOPE is defined as change in lift coefficient per change in angle of attack.
