TABLE II.
ALTITUDE CORRECTION CHART
Corrections for altitude above or below altimeter readings of 450 meters.
Three values to be added to values from Table I.
EXAMPLE OF USE OF CHART
1100 + 900
Mean of altitude reading is
= 1000 meters.
2
Find intersection of 1000 M and wet bulb 60 F and interpolate between items,
giving approximately + 0.0007. Add this value to value obtained from Table I. 1.063
+ 0.0007 = 1.0637
Corrected altitude difference = (1100-900) (1.0637) = 212.74 M
