8. An a/c is flying at FL290& oat -30 c.the temp condition is ...
"Temp condition"? Never heard of it.
It's a fill-the-blank type of Q, Pete. Temp = temperature, a common
Indian abbrev

I understand the concept of "fill-in-the-blank". And believe it or not, we
do abbreviate "temperature" as "temp" too, now and then. The problem is
that the term "temp condition" is not one that's meaningful to me (and
likely not to most other US pilots, if any).
9. In convective clouds severe icing may be encountered at temp...
Care to finish that question?
Same as above. It's a fill-the-blank.
Again, it's apparent that it's "fill-in-the-blank". What's not apparent is
what the blank might be. Are they asking for an actual temperature? Do
they want the word "condition"? Who knows?
Anyway, as a stab at answering it: in convection, you can get icing with
nearly any outside air temperature, since freezing moisture may be carried
up or down within the cloud into an altitude of non-freezing temperature.
At some point, it just gets too warm, and the airframe is too warm for any
ice to stick anyway, but I would not be comfortable stating any one single
temperature above which you are guaranteed safe from icing (well, okay...I
suppose 40C would be a pretty good guarantee...but that's probably not where
the "official" cut-off is).
11. When an a/c climbs at constant TAS,RAS shd be
a.Increased
b.maintained
c.decreased
"RAS"?
I suspect it's IAS. I've not heard of RAS either
If one assumes it's IAS, then constant TAS requires decreasing IAS as one
climbs. If "RAS" means something else, all bets are off.
