Hi there,

Here is a little guidance list, giving the whole explanasion will be eventually writing a book, so I will just keep it to your request.

After confirming the right database on your FMS and confirming the right set of engines this is the steps you have to follow;

1) On the POS INIT "Position Initialisation" page, you enter the VOMM on the REF AIRPORT box.

2) After this you copy the GPS POS cooridnates and paste them in the SET IRS POS box. Keep in mind that your IRS selectors on the overhead panel need to be in NAV position.

3) After this you continue to the ROUTE page, here you enter the ORIGIN airport (VOMM, in your case). And in the DEST box you enter VOHY.

4) Then hit the NEXT PAGE button on the FMS and enter on the right top side the VOR MMV (You may have to confirm which MMV you want, because there could be more in the world with the same name), it is the first one with the coordinates "N12 59.2E080..." (I looked it up for you). And as final, on the second of the top right you enter the BODEL.

5) Now you have completed your route, you only have to press activate and the EXEC "execute" button.

6) And your final step is on the PERF INIT page, on the top right you enter 200, this will set your Cruise altitude for FL200. ENJOY!

In the real world operations, you have to fill out way more information, such as weight, fuel, departure and arrival routes, t/o performance and t/o config ect. Bit this is wat you asked for, the rest you can find in the manual or just search on youtube. If you want to do it the right way, look for a FCOM or a FMS training manual of the 767.
