RMI

Featured Replies

In the article that was discussed in today

The RMI is like having a heading indicator and an ADF mushed together.The arrows are called 'pointers', and like an ADF, and they point to a navaid. You can assign to pointers to VOR 1 frequency, the VOR 2 frequency, or the ADF frequency. There are little switches on the lower left and right hand side of the RMI, and switching those flip the pointer from VOR 1, VOR 2 and ADF frequencies.The RMI shows you the relative bearing of the station with respect to the nose of your aircraft. If the pointer was pointing straight up, the station would be directly in front of the aircraft. If the pointer was pointing sideways, the station would be directly off of your wingtip. If the pointer was pointing straight down, the station would be directly behind you.To use the RMI, first tune a NAV radio (VOR or ADF) to the desired frequency (and confirm the identify of the station by listening to the its morse code identifier), and then depress the small switch on the lower left or right hand corners of the RMI faceplate to 'slave' a pointer to the station you have tuned. The button on the lower left hand side controls the single-line pointer, the button the lower right hand side controls the double-line pointer. Switching the lower left hand button slaves the single-line pointer to either VOR 1 or the ADF, pressing the lower right hand button slaves the double line pointer between VOR 2 and the ADF.It's a very useful instrument. Hope this helps, Rudi

So to answer your question, yes, if you tune a localizer frequency in VOR 1 and you set the single line pointer to VOR 1, the single line pointer will point to the localizer transmitter.

...and if you "spin" the compass faceplate to your actual heading, then you can figure out what your "relative" bearing to station is...no? At least that is what I remember.

That's pretty close. Relative bearing is the number of degrees (going in a clockwise direction) from the nose of the aircraft to the station.The formula you are referring to is:Relative bearing + magnetic heading = magnetic bearing

If you guys (and others are welcomed) please answer this with reference to the two needle colors in you explantion.Here is the simplist way I know to ask my question.1. please read my initial post.2. Please help me with this example:A. In the defualt King Air.B. Nav 1 is set for ILS frequency. (I can do this and work the trottles watch guages and stay on slop, and use only FD (W/O) AP on Appr) and it goes well also. Thus what are the remaining options avalible for the RMI. And to what needle on the RMI avalible to be slaved or assined to. Please use the color of the needle you are discussing in the RMI.********************************************************************Rudi, if you could update your last comments in reference to neele * color or single or dbl needle that would really help.*********************************************************************OK here is the other way I am looking at this. Normally I use the (main center) HSI (defualt king air) and the main (I am the one calling it "main"), OBS. Then while tracking a VOR (this is before the first example I listed here). prior to getting in the range to input the ILS freq in the Nav 1. So while in air and I find the Vor freq for my airport or the nearest Vor freq and I input into Nav 1, I will track it using the OBS, ( you know twist spin and track, (I relize in some craft once the Nav 1 is getting a signal from the Vor you could hit the Nav buttom on the radio stack and it will do the adjustments and fly you there, but the comment is not for arguments sake its just to let those that use this feature I am aware of it). ******* So I am tracking a VOR at the field I want to and or have filed a flight plan for using the Nav 1 (it has the mentioned Vor freq input, all is going well, Since Nav 1 is slaved to the Vor I,the Vor to get to airport (at this point realize I will use fix, dme, the vor mentioned to put me in a position to track the ILS as mention in the first example).*********** So if I am in route tracking VOR I signal to my Nav 1 radio, what are the remaing options to use the RMI for. (please use the RMI needle color or the dbl or single needle).**********************************************************************************************************************************So the bottom line is this:EX 1. If using the ILS in the firsr example in this responce what are the remaing options for the RMI as Nav 1 is tied, slaved, whatever to the ILS freq. EX 2. If tracking a VOR signal in your nav 1 what are the remaing features for the RMI. I understand the various info positions of the RMI selector but cant firure out (I read the FAA section but it was not specific in example, but I am in this example almost every time I sim, LOL, (I really like staying in tune with VOR appr, "even though the FAA says they be gone in the near future"). Thus if the Nav 1 is tied , slaved to the Nav 1, then with Nav 2 only being left what are the different uses that can take place with the Nav 2, and the functionality of the RMI. IE, We got the Nav 1 (even with stand by tied/slaved to ILS or VOR example I mentioned, in the defualt King Air). So in each example what can we do in the (Defualt King Air) nav 2. Lets try to incoorperate the stand by in the Nav 2 of the radio stack and the Nav 2 main. With the ability to switch fuctionality in the RMI dose relate to the exact funcionality that there if we only used (please defualt King Air 350) we only used the Nav 1 radioIE, Now we (know for an ILS appr it must be in the Nav 1 to use (if avalible) to capure and fly any level of an ILS, ( as cat I, II of III. At least my understanding is it must be on the Nav 1 radio.

OK,Now is it the same for the single needle if you are using the vor to the nav 1 durring an ILS appr, as with the vor tied to the Nav 1 tracking in relation to tracking a VOR. Would you please also refrence the dolor, (also if its the dbl or single ndl when looking at the RMI).I appreciate all the help. I feel I spelled ouyt the question as plain as could be spelled out.I have read all the mentioned FAA and other text mentioned in the previous mentioned articles here as well as a few previous post.My goal is this:In the defualt king air,(at this point please use the two examples I listed in detial in the relation of having the Nav 1 tied/slaved to the (this means a vor to guide you to a landing field) and then the second example is say I am in a position to input the ILS inro the Nav 1 for omsturment appr.Thus please explain the functions that the Nav 2 can perform (as in the RMI), please use needle colore and the fact that the needle is dbl or single, this is to assist me to understand what you can and cannot do with the Nav 2 from your stack when slaving (the nav 2 ((please explian the other options that can happen with the nav 2 in relation to how they work if other than the RMI. I dont mean to be a pain but know that the defualt King Air panel can do a little of this and that. Its hard to read , study other lessons with different craft, ans apply when trianning planes have specific pannels for this. Those with all the guages sigle and whay not, and turn around and apply to an ai craft thats defualt, and a great planeSo the RMI in the king air (defualt, this is the question:As mentioned the Nav 1 is to VOR 1 or the ILS (when avalible), or say the Nav 1 is tied to the VOR from the airport.Thus the case what are the multiple function of the Nav 2 radio and what are the options to use the Nav 2 freq (king air defualts, please).If the nav 1 is used for vor tracking and nav 2 to another,(please fill in, only with king air defualt please).As in using the Nav 1 for so called secondary. Aka, isaw and read a coulpe examples to swap nav 1 to nav 2.This is my best way to ask:When using a defualt knig air and when the Nav 1 is tied to a freq, then whats left for the nav 2 that is tied to the nav 2 on the radio stack.Now the other way, say nav 2 is to the VOR at the airport other than, that as what would have been used as as nav 2.Please, With Nav 1 being that it is,then the Nav 2 tied or slaved to the nav 2 freq hoow do I use the RMI in the defualt kin g air to make some reason of the bilities of the nav 2 when nav 1 is for the ILS or the peimary VOR.I really appreciate the belp, and please note alkl the examples as they "come to the same example". If anyone can offer some help as I keep hitting my head please advise.I am relly confussed, I "welcome your all's" help.Thank you.Mark.I hope one day to help repay the group. I know you all are laughing, but may be I can help down the road.Thank you.Mark.

Please let me know if the questions are not clear. I ment them in the context of two questions.1. with ILS being used on the Nav 1.2. with the Vor being used in the Nav 1.Thanks,Mark.

Hi Mark:First let's make sure we are referring to the same instrument. The RMI is the instrument located directly below the airspeed indicator in the B-200.The Yellow pointer is the arrow with the single line. The Green pointer is the arrow with the double line.The yellow pointer can point to one of only two stations: the station tuned using VOR 1, or the station tuned using the ADF. The green (double) pointer can point only to VOR 2 or the ADF. The switch that controls whether the Yellow pointer is slaved to VOR 1 or the ADF is located on the lower left hand corner of the RMI faceplate. The switch that controls with the Green point is slaved to VOR 2 or the ADF is located on the lower right corner of the RMI faceplate. RMI pointers cannot be set to point to GPS or RNAV waypoints. They can only point to VOR or NDB stations.Hope this helps answer your question, Rudi

Rudi,Thanks.I still need some of the info cleared up, please.First, I was wanting reference the defualt king air 350, but I assume the insturments are the same in both planes. I know to not assume thu the question. I did not buy the payware plane. You stated,"The Yellow pointer is the arrow with the single line. The Green pointer is the arrow with the double line.*The yellow pointer can point to one of only two stations: the station tuned using VOR 1, or the station tuned using the ADF. The green (double) pointer can point only to VOR 2 or the ADF. The switch that controls whether the Yellow pointer is slaved to VOR 1 or the ADF is located on the lower left hand corner of the RMI faceplate. The switch that controls with the Green point is slaved to VOR 2 or the ADF is located on the lower right corner of the RMI faceplate."In the second paragraph I placed an * by it.Can you tell what you mean when you state: "station tuned using VOR 1, or the station tuned using the ADF"I am wanting to know what you saying. I am thinking that Nav 1 can be tuned to what, and Nav 2 can be used for what. Please understand I am not being an "####" I am still a bit mixxed up, and I think it is due to the baseline and base frame work in our references. Are you saying that the yellow can be slaved, or "tuned" to Nav 1 can only being tuned to a vor or a adf.And the green arrow to Nav 2 foo a vor or adf.In other words nav 1 is for the yellow and nav 2 is for the green.If thats the case, the it dose not matter what vor freguency is tuned in the nav 1 or nav 2, as lond as you know that yellow is for nav 1 and the green is nav 2.I hope this makes sence, and I appreciate your help and others input.Mark.

Try this simple exercise Mark:1. Create a new flight using the default B-350. Start from KISP on runway 6. Don't take off or fly, just keep the airplane on the runway, facing east.2. Tune NAV 1 radio to 117.2. That's the Calverton VOR station (identifier CCC), located about 12 miles to the east of KISP, directly off the nose of the aircraft. Notice that the yellow arrow on the RMI is pointing up. It's pointing in the direction of the CCC VOR.3. Tune the ADF radio to 366. That's the LOKKS NDB located 5 miles to the southwest of KISP, directly behind the aircraft.4. There is a button on the lower left hand corner of the RMI faceplate. Click it. Notice that the yellow arrow (single) changes orientation - from pointing up to the CCC VOR, to pointing down, in the direction of the LOKKS NDB. In other words, clicking the switch on the lower left hand corner of the RMI faceplate changes which radio station the yellow arrow is pointing to - it can point to either 117.2 (the VOR), or it can point to 366 (the NDB). Clicking that button again sets the yellow arrow to point to CCC VOR.5. The green (double) arrow operates in exactly the same manner, only the green arrow points to the station tuned in NAV 2 or the ADF. Dial 117.7 into NAV 2 radio. That's the Deer Park VOR (DPK) about 10 miles west of KISP. Notice that the green arrow is pointing towards the DPK VOR. 6. There is a button on the lower right hand corner of the RMI faceplate. Click it. Notice that the green arrow is now pointing towards the LOKKS NDB. Click it again a second time and the green arrow points to the DPK VOR. Doing this exercise will give you a sense of the functionality of the RMI.The RMI has two needles because you can determine precisely your own location if you know the relative bearing of two different transmiting stations. It's not possible to do that using just one needle alone.Again, hope this is helpful - good luck!

Thank you.I will give it a go.Is it possible to address the specific two questions I had in responce to your kind post here. I belive it was the one before this one.I would really appreciate it.You really have been a big help. I dont mean to be so pickey, but dont want to assume anything.If you think it would help, I would be happy to jump on Team Speak. This in an effort to simply save time and effort on your part. If you have a preference then let me know. I am on the reciving end here, and feel obligated to ake the offer in responce to your kind efforts.Agian, I referenced the following the time before and would greatly benifit fron you reszponce, in conjunction with the exersice you Rx (prescribe) here.Here we go,"In the second paragraph I placed an * by it.Can you tell what you mean when you state:"station tuned using VOR 1, or the station tuned using the ADF"I am wanting to know what you saying. I am thinking that Nav 1 can be tuned to what, and Nav 2 can be used for what.

Sorry I cannot edit, dont know so I will go with what I got.The question I hope you do address is the one of this subject matter. I ask your patentce as the edit I tried was lost thus 20 min where shoot.The main thing I want to know is this:On Nav one what are the options avalibe when using the rmi to display the freq inputted into the nav one. You mentioned reporting station. I was under the thought that the freq was inputted into nav one or two. Thus if a freq is inputted into nav one what are the options for the RMI ti inturpet for you. Also what are the choice of freq's that can be put into the nav one, at this time I understand a vor and a adf, this may be wrong,?Thus I dont use the terms reporting station. From the lessons in the sim I left with the framework that a freq number is put into one of the two radio nav areas. (please be aware I am somewhat knowing that you input the B- presure into a different area and a few others).In dealing with the radio stack nav one and Nav two and the abilit's, in relation to the RMI, I ask this.If a freq is in the nav 1, what are all the options for the fuctions of the RMI.If a freq is in the nav2, what are all the options for the funtions of the RMI.I thank you agian for the baseline knowledge of the RMI and the intentions of the functions.I am really wanting to know the specifics of the rmi when used in relation to the freq in nav 1, and the same for nav 2. The reason I am so specific in my quest is that it took me a long time (I will blame this on being left handed, ((all those who want and or be offended, its just a joke from a southpaw, take it easy)), LOL), I say agian a long time to realize the nav one and nav 2 can track different vor's, (((the freq in the nav one, and the freq in the nav 2))), but did not know for a bit ((((when getting started that nav one was the only nav that coould be used to intercept and follow an ILS)))), agian I am left handed, LOL.My hope is the text I have posted here gives you and others who can help a framework to allow you to know where I am comming from.I really appreciate the time you have taken, and am sorry the origional responce I made, was lost (I konw its my error), but I look forward to gaining the knowledge. Again, "I sure owe ya",Mark.

"If a freq is in the nav 1, what are all the options for the fuctions of the RMI."- the yellow (single) needle will point to the NAV 1 VOR"If a freq is in the nav2, what are all the options for the funtions of the RMI."- the green (double) needle will point to the NAV 2 VORI encourage you to try the little exercise described above. I tried it myself just now, and found that I had to slew the aircraft up to about 500 feet in order to be able to receive the radio signals from CCC, LOKKS and DPK.To slew an aircraft in MS2004/2002, press 'Y' - that puts you in slew mode. To raise the aircraft up vertically, press 'Q' a couple of times. To slow upward movement, press 'A'. You will see the RMI needles move and you can do the exercise while the airplane is in slew mode.
