1.	If I want to design an aircraft which primary flies in a low speed region then, which type of drag shouldn’t be considered?(a) Wave drag(b) Parasite drag(c) Induced drag(d) Form drag onlyI got this question in an interview.I want to ask this question from Aerodynamic Forces in chapter Aerodynamics of Aircraft Design
Answer» Right CHOICE is (a) Wave drag To elaborate: Wave drag is drag produced at HIGH speeds. At SUPERSONIC or near supersonic SPEED due to shock formation, the wave drag is produced. Hence, for low speed AIRCRAFTS, the wave drag is not a key parameter.
