Recall 360 to 6 into Melbourne on the night shifts, so same same. Call us on Approach at 35 miles just left F350 on the drop. Straight in 16, 10,000 at Bolinda. Cool.
Loved watching trainess try to make you number 2. [Edit to add: What our Flows used to refer to as a "gorilla with a machine gun" i.e. Don't let anyone get in his way - give him what he wants! ]

Not exactly sure what you are driving at but you need to understand the concept of aircraft transitioning from IAS to Mach No. on the climb and vice versa, on descent.

For most jets that happens around 26-28,000 ft so although F250 is a touch on the low side it is chosen as a cutoff where Mach number or IAS instructions should normally be issued.
In fact, decent en-route controllers (like On the beach ) will normally provide a reduced Mach No. into an IAS if a speed reduction is required from top of descent. e.g. M 0.80 into 270 KIAS.
If you just say 270 KIAS on descent, that can actually be a speed increase at upper levels.
It's instructive to look at a table of IAS, Mach No., TAS vs Altitude to learn what is going on up there.
