How to use an RMI

I know for a fact that AM travels further, much further, at night. Here is one wiki source but if you need more I have no problem digging them up: "However, after sunset, changes in the ionosphere cause AM signals to travel by skywave, enabling AM radio stations to be heard much farther from their point of origin than is normal during the day."


Also, the stations in Europe are stronger than ours are, at least according to him this one was. Can anyone confirm high power NDB's in Europe?

The nightime part is true, dont know why I typed daytime?? I was thinking of the "night effect" before I started typing but had a brain fart I guess...
 
When I was driving truck I had a CB conversation with someone in Miami while I was driving in ND. If the conditions are right one can catch a skip a ways out.

Got me wondering....are CB's still in widespread use in the trucking industry?
 
Very true. Flying night cargo, and 40 miles from PHX, I coudn't pick up the local PHX AM news station, but could listen to an AM news station in LA clear as if I were right there.

We had an ADF in the O-2 and often I would listen to AFVN Saigon, same one as in "Good Morning Vietnam". Anyway, finished working a strike on a set of coords with bombs using delayed fusing and napalm. Blowing stuff up. Burning things down. Anyway as we finished the strike I noticed I had not turned the ADF off and playing was Jose Feliciano, "Baby Light My Fire." Coincidence to be sure. (fwiw, napalm was not that useful except in rare cases)

A fitting coincidence! Our current travel pods we use on fighter-type aircraft.....MXU-648 or something like that....I believe were old BLU-27 nape pods, converted with a panel door on the right side and turned into a baggage pod.
 
The RMI you will use is essentially a DG (although it is a slaved to the flux generator like the HSI, IE don't have to adjust it to the compass) with 2 needles in them. There are 2 buttons, you can select NAV (one needle for nav 1 and another for nav 2) or ADF mode (there is only 1 ADF so if you switch both to ADF mode they'll point the same direction, but you can have needle 1 on nav and needle 2 on ADF or visa versa, or both ADF to reduce confusion). Either mode the pointer on the RMI needle will point to the direction of the nav aid and the 360 position on the RMI will be whatever heading you're flying.

I actually have a tendency to use the RMI to do VOR approaches actually. The tail always points to the radial you're on, its kind of easy.

Also makes doing airborne VOR checks really easy.
 
Ok, so i'm pretty sure I understand. I know with a movable card I always just leave it on 360 and when its 45 degrees off, start turning to the inbound course.

With the RMI, your heading is for example is 305, lets say the inbound course is 350. Do you wait until the needle is on the 350 bearing to turn to it or do you lead it by the same 45 degrees? I can see how it works in my head I just want to make sure i'm right. In my head I almost see it working more like a LOC approach with an HSI. Where you are on an intercept heading and once the needle gets close to pointing to the inbound bearing you just turn to it and stay on it. Is that correct?

You wait until the needle is at (head falls to) the appropriate amount of lead course (akin to a lead radial), then turn towards it so when you get on 350, the head of the needle is pointing to the top of the case at 350 (no wind). Same principle.....same thing you're trying to accomplish......if you had a CDI of some type.

Correct for Courses-TO. Do the opposite with the tail rising, for Bearings-From.
