Any way to set the Barber Pole higher?

[SORSRR]

It's set now at 246 and I'd like to raise it to 285. Any way in the air or cfg files?

TIA

No it isn't.

Your question is based on one or several misconceptions.

The IAS which equals a given Mach number varies with the surrounding atmosphere. You cannot set a Mach limit equal to an IAS limit. They are different things. The aircrew must restrict the profile drag (IAS) of the aircraft to whichever of the two different structural failure limits is most restrictive at the time.

The barber pole indicates the IAS (profile drag) which equals the chosen limiting Mach number in the current atmosphere. There is no constant that it can be set too. That is the whole point. If it could be set equal to an IAS it would be just a red line on the ASI and no pole would be required.

Like all needles in all gauges a barber pole is driven by the flight dynamics.
The relevant real world Mach limit (Mne or Mno) that needs to be indicated by the pole in a particular type (role) of aircraft is encoded in the aircraft.cfg.

So for instance in a Boeing 377 Stratocruiser;

[Reference Speeds]
flaps_up_stall_speed=114 //Vs
full_flaps_stall_speed=80 //Vs0
cruise_speed=265 //Design cruise TAS
max_indicated_speed=271 //Vno
max_mach=0.52 //Mno

What IAS equals the Mach 0.52 limit varies with the atmosphere, moment by moment, You must never allow the IAS (profile drag) needle to merge with the barber pole regardless of the IAS (profile drag) the barber pole is indicating is the current Mach limit in the current atmosphere, else you may rip the tail off regardless of how low that IAS (profile drag) may be.

You must avoid adding fatal transonic shock regardless of how low the current profile drag (IAS), which is already trying to rip the tail off, may be at the time.

There is nothing remotely odd about transonic shock ripping the tail off an aeroplane when the existing profile drag is only 246 KIAS. You want the barber pole to warn you that you are about to die as you lose control of your energy state and induce fatal transonic shock in cold air at only 246 KIAS.

Cold kills!
