Calculations

Question 1

Compressibility

Answer 1

= TAS/100 - 3

Question 2

The suitable altutude before turning to the final?

Answer 2

To remember angle x NM x 100 = 3 x 4 x 100= 1200 + Threshold =1900

Question 3

Maximum allowable Wind speed? q: 616046

Answer 3

CWC = WS x sin ( ° )
20 = WS x sin ( 100° - 063° )
WS = 20 ÷ sin ( 037° )
WS = 33 Knots
