I'm an airline pilot and i figured how to make ILS interception calculations with the TADS computer.

During private pilote courese we have to manipulate a jeppesen slide rule for navigation. But the TADS computer is way more complete.

Cheers.

interesting i would love to see how you did that ATPL (finished a couple of months ago) is also what brought me more close to using sub-tools i would ignore previously. the attack disks feels similar to the E6B we used to have to do our calculations too general navigation is very similar too, so im in the process of maybe printing some maps on plastified paper so i can plop my routes using my beloved CP-RLX plotter
Clear skies and Good hunting keleun!

Sure! Here it goes.


Lets say you are going to intercept at the IF (intermediate fix) at 10 nm from the threshold and at an angle of 70 degrees.

Align the 10 of the speed scale (in this case the speed scale will act as distance) with the 70 of the degree scale.


Now heres the part that you have to have a previus knowledge of turn radius.

If you are flying at about 180kt ground speed, your turn radius is about 1nm.


Just look for 1 in the speed scale and read opposite to it the degrees, in relation to the final approach course, you have to start turning to be stablished on the localizer.

You can also do it with a calculator.

Arctan of turn radius / distance of intercept



If you are interested in mental math for pulots i would suggest the excellent book "M3 - The mile, The Mach, The minute" from Mike Roumens.
