All propeller-driven aircraft use km/h, mph and kn as speed units. Meanwhile, all jet-powered aircraft use Mach, km/h and mph as speed units. Since the I-270 is jet-powered, it should use Mach as the max. speed main unit. - Carlo71201 (talk

Other aircraft I've seen use the mach number even though there is a certain altitude indicated.

Your statement that all jet powered aircraft use Mach, km/h and mph as speed units and that all' propeller-driven aircraft use just km/h, mph and knotsis unfounded. There are many jet-aircraft which are very subsonic and not mach-limited, while some prop-driven aircraft can get into transonic speeds where mach number is relevant. While the guidance in Wikipedia:WikiProject Aircraft/page content suggests use of Mach number for supersonic aircraft (not Jets or otherwise), it says nothing about the order of them, while mach number cannot usefully be added unless it is sourced - either directly or where a speed is quoted at a specific altitude.Nigel Ish (talk) 17:04, 21 June 2017 (UTC)Reply
