At CAS 250kts, FL390, JSA +8*C what is the TAS?
A)439
B)482
C)458
D)464
The ans is given as 464kts, but I keep getting 482... the only way to get to 464 is to use ISA values for the temp, am i right in thinking the temp in this question is
-55? or have i messed up because its the JSA???
Confussed???!!!
