Sunrise

Sun RISE while facing west, Concorde en route to Barbados.

Unfortunately, yet again, icing from non existent clouds lead to airspeed failure in the climb so an overspeed as I tried to control it manually, then above FL100 I went to check the taxi lights were off and switched the landing lights ON instead, another penalty!

Surise in the West eh!?

As real as it gets

Surely you don't need clouds to produce icing?

In clear air vehicles can ice up. The other day I was driving in wall to wall sunshines with little bits of snow forming out of the air.

Aeroplanes I would think can do this if the conditions are right

Well, generally speaking you do need cloud or precipitation, to produce airframe icing , and the pitot system is essentially part of the airframe . Different considerations apply in relation to engines where intake icing can occur in conditions of high humidity because of the reduction in air pressure in intake tracts ( and the most usual form this takes is in carburetted piston engines ). Did you have pitot heat on ?

Supersonic, travelling faster than the earth is turning, yes, completely real!

You need sub zero air temperature and visible moisture to form airframe icing (as mentioned carburettor icing is totally different)

Pitot heat was on, part of taxy checks, but MSFS can still ice up the pitot sensors with it on!

Ah no, with all due respect, you do not need sub-zero air temp to produce icing. A rapid descent with a supercooled aeroplane into precipitation can produce some quite nasty ( even if relatively transient ) icing even when you are below the freezing level

[adysmith]

You are correct, I am aware of "rain ice". Even so, visible moisture required, which was not present at the time in question.

Also hardly the case shortly after take off
