Converting Mach to Knots

[Delta2014]

Hello,

I have been studying a couple of charts from the F-106 Delta Dart flight manual, and the speeds shown are in mach.

Since mach changes at different altitudes, I was curious to know if the charts in the manuals showing mach numbers use static mach numbers (1Mach = 661.47knots).

Or, do the mach numbers on the charts need to be converted to knots with an aviation calculator such as the one on this page:

If you would like to see the charts in the F-106 manual, you can download the manual here:

The manual I downloaded is:

T.O. 1F-106A-1 (1969, rev.1972)

Take a look at pages 6-8 to 6-18.

Thanks very much,

Mach Number depends only on temperature. The conversion link you included will give you mach number for standard atmosphere temps at various altitudes.

No conversions from these charts. The way the Air Force does their manuals, the "Dash One" (T.O.F106A-1) covers operating procedures. Any charts are to illustrate guidelines or limitations. In those charts you are concerned with, they are only illustrating the mach envelope of the airplane.
If you want specific operating numbers, you have to go to the "One Dash One" (T.O.F106A-1-1), which is the performance manual.
This arrangement applies to any Air Force aircraft: The Dash One is the operating manual, the One Dash One is the performance manual. You gotta have both to fly.

When interpreting charts in the F-106 Delta Dart flight manual, which display speeds in Mach numbers, it's essential to consider the altitude at which the aircraft is flying. These Mach numbers are relative to the local speed of sound at the specific altitude.
