Gust load factor and altitude

Keith,

Do you think we could use the same reasoning to answer the following question:

Is the Gust load increasing or decreasing when altitude increases (IAS and all other factors of importance constant) ?

I assume vertical gust.

Altitude 1 < Altitude 2
IAS1 = IAS2

Using your argumentation I get this formula :

L2/W = gust load = Rho2 (TAS2)² / Rho1 (TAS1)²

If IAS constant, when altitude increases TAS increases too. However air density decreases much more thus gust load decreases.

Could that be a good explication ?

Thanks for your answer Keith.

Have a good day,
Emmanuel Cordier.
