True altitude = Indicated altitude + (ISA dev x 4 x Thousands of feet)
= 16000 + (-10 x 4 x 16)
= 16000+(-640)
= 16000-640
= 15360ft (on 1013.25)
Height difference is 1013-1003=10Hpa
therefore 10Hpa x 30= 300ft of height difference between 1013 and 1003
so 15360ft-300ft=
15060FT(1003hpa)
silly numerical man!!!
you made me remember my primary school days man thanks
