Main trade-offExcellent speed, range and cabin for the used price, but ageing pressurization and two turboprop engines require professional management.The Conquest II Dash 8 combines 7-seat turboprop capability with about 1,170 NM reported range and about 291 kt reported cruise, while payload, runway and operating-cost figures remain indicative and should be verified for the specific aircraft before making a decision.Strong value and practical performance, but ageing pressurization, systems and PT6 status require specialist diligence.
