Flite Idol,

My comment regarding the reduction in TAS with increasing altitude was related to maintaining a constant Mach No.

As temp reduces with altitude so does the TAS associated with a constant Mach No.

I was trying to refer to flight where Mach No. is the limiting factor and not the relationship between EAS & TAS with changing density.
