BOAC,
Q,3 was a typo from me I understand that IAS will Increase wit a constant TAS climb.
TAS will increase with altitude and are the speed witch the airplane moves through the air.
My understanding of IAS is that it does not change with altitude since it measures the difference between static pressure and dynamic pressure.
The question about LD/MAX is a question Delta ask on there interview and I have been trying get a good enough understanding on the subject to answer that but I'm just not there yet...
I been an instructor for the last 2 years and are getting ready to go to the airlines. I have 3 interview coming up and realize that my high altitude knowledge together with my understanding of Mach is not where it should be.
I am not trying to find a easy way out by asking questions here, but lately I have been reading a lot of books and seem like I have just confused my self even more.
