Altimetry - me dim, a Q
I've posted this onto Tech Log but from experience Rotorheads is something of a centre of excellence with regards to technical stuff (I appreciate that the below is noddy) and so are hoping that mod will let is stay for a bit.
I am much confused but beginning to see the light with regards to altimetry. If someone could be kind enough to explain the solution to the below Q, it would go some way to completing my understanding of some fundamental concepts in altimetry.
I have worked on it and think I have the right answer - an explanation will confirm it and assist my general understanding. Thanks very much in advance.
Minimum safe altitude in an area is 12,000ft. QNH at a local airfield is 1030hPa.
Average temp of atmosphere is ISA+10. What will altimeter read at this safe
altitude?
a) 11250
b) 11520
c) 12210
d) 1730
