We now equate the larger of the two DME's with which we are working to the outer radius of
the RMI card. The other, or smaller DME, will be somewhere proportionally between the outer
edge of the RMI card and the center (TACAN station).
Your position: 130º R/20 DME
Desired position: 200º R/40 DME
Remember now, your position is on the 130ºR; therefore, it lies somewhere along the tail of
the #2 needle. Now note which of the two DME's is largest--40. Therefore, 40 DME is the
value assigned to the outer edge of the card. Our DME is 20, so it must be halfway between the
compass edge and the RMI center.
