A supersonic aircraft is an aircraft which can exceed the speed of sound (Mach 1.0) in level flight. Type Country Class Role Date Status No. Notes Aeritalia F-104S ...
A Machmeter is an aircraft pitot-static system flight instrument that shows the ratio of the true airspeed to the speed of sound, a dimensionless quantity called Mach number. This is shown on a Machmeter as a decimal fraction. An aircraft flying at the speed of sound is flying at a Mach number of one, expressed as Mach 1.
The Davis D-1 was developed from the Davis V-3, which in turn was developed from the Vulcan American Moth. The Davis Aircraft Corporation had its factory at Richmond, Indiana . The D-1 is a parasol-winged aircraft of mixed construction with a two-spar wing and a rectangular welded steel-tube fuselage , the whole being covered by fabric.
The drag-divergence Mach number (not to be confused with critical Mach number) is the Mach number at which the aerodynamic drag on an airfoil or airframe begins to increase rapidly as the Mach number continues to increase. [1] This increase can cause the drag coefficient to rise to more than ten times its low-speed value.

The interaction of shock waves from two supersonic aircraft, photographed for the first time by NASA using the Schlieren method in 2019. A supersonic aircraft is an aircraft capable of supersonic flight, that is, flying faster than the speed of sound (Mach 1). Supersonic aircraft were
The subsonic speed range is that range of speeds within which, all of the airflow over an aircraft is less than Mach 1. The critical Mach number (Mcrit) is lowest free stream Mach number at which airflow over any part of the aircraft first reaches Mach 1. So the subsonic speed range includes all speeds that are less than Mcrit. Transonic: 0.8–1.2
The Premier 1A has a Mach 0.8 MMo, 451 kn (835 km/h) cruise at FL310 and a 817 lb (371 kg)/h fuel burn at 424 kn (785 km/h) and midweight. It can fly four passengers over 1,105 or 1,365 nmi (2,046 or 2,528 km) with two passengers and can take off within 3,792 ft (1,156 m) at ISA temperatures and sea-level.
