"Realistic Navigation" - yellow light

[Freelansir]

Gents,

We are getting off-topic here from the question.

This thread is not about ILS systems nor tutorials on landing as I am familiar with them in FS2004.



It is about a gauge that is in the B-25 in IL2 and what the yellow lamp means.



I have searched the internet for pictures of B-25 cockpits and have found none that show this gauge nor this lamp.

Ergo, my question.

I appreciate your interest though.

Blind Landing System for Royal Air Force Equipment

Top of page
Abstract

THE Air Ministry has announced its intention to equip all R.A.F. bombers and reconnaissance aircraft with the Lorenz blind approach system. If experiments during this winter prove this to be successful, the fighter class of aircraft will then also be so equipped. This follows the announcement that forty R.A.F. aerodromes would have the radio transmitting apparatus for this system installed, as mentioned in NATURE of November 26. The apparatus to be carried in each machine weighs 50 lb. and costs about £200. Its manipulation demands a certain technique, and pilots need, considerable practice before being able to use it in addition to the other movements and observations that are incidental to the operation of landing a modern high-speed aeroplane. A special ‘Link’ trainer is used for practice in the use of the Lorenz system, upon which approaches and landings can be simulated without leaving the ground. These are to be provided at R.A.F. flying schools, in addition to which each service station will carry one. The training of the personnel will be undertaken by special instructors, who will have already attended courses at the Central Flying School at Upavon, Wilts.

What I'm trying to explain is that the function of that light is the same as it is for the Lorenz system, I.E. it illuminates while you're passing over a beacon and then extinguishes.

I'm not claiming the AN/MRN-1 functioned like this in real life, merely that it is possible Team Daidalos implemented it in this manner.

I think that everyone is on topic.. you failed to identify the possibility that the ILS systems then, might have only had one indicator. This was when it seemed to be working the same way as today's 3 beacon indicators

This B25 has two instruments both with indicator lights, watch full screen.

jameson, I thank your effort in finding that video. You must've scanned many YouTubes. However, I already know those gauges are called I-101 indicators and I cannot see any lamp lit or unlit.




Pfiel, I was hoping to hear from the TD members who developed this wonderful feature and give them their due credit and thanks.

I will continue to pursue the mystery of the "yellow lamp" in the B-25J introduced in version 4.10.

Thanks to all who read my thread.

Take care,

I've marked them for you. They are clearly visible in the video full screen and highest resolution.

Freelansir,
The essential point of the indicator light is given in the system's name "The Lorenz BLIND landing system". I.e. unlike your fs2004 picture the system was used when you cannot see anything out of the cockpit, it's dark or you are in cloud with a low base. Having reached your airfield via the homing beacon, when the lamp first lights you begin the glidepath descent to the runway. The second time it lights. and here's the good bit, if you cannot see the end of the runway it's time to get the wheels and flaps up and get the hell outa Dodge to go round and have another go!

I suggest that you download and read the release notes from the 4.10 patch available here:
http://www.mission4today.com/index.p...etails&id=3996
which is when these features were added to IL2. You will find the relevant info under New Navigational Objects. There are also some pdf's in the game's folder together with the game manual which contain lots of useful info.

See http://www.usaaf.co.uk/forum/viewtopic.php?f=40&t=197 for explanation of the systems used by USAF in England during WW2. From there this image, is this in the game? click on images to enlarge.


Anyone whose wishes to learn more can download the Army Airforces' WW2 Air Navigation Manual from here:
http://aafcollection.info/items/deta...!1!title!up!20

You can download it in parts. The one most relevant here is:

Section 4: Supplementing Dead-Reckoning by Radio
The Radio Line of Position: The instruments and their use; Obtaining the uncorrected radio bearing; Converting uncorrected radio bearing to radio line of position; The radio fix and log; Other radio and communication equipment in the aircraft.

Additional Radio Aids: Radio range stations; Marker beacons.

and this page the most,


At about at the war's end the first completely automatic landing took place in England and is the forerunner of the system in use today. Some of you may not know but nearly all civil flights are landed today by the aircraft's onboard computer which may or may not make you sleep easier

Can be landed under certain conditions not too often met true, are landed wrong. 13 years in airline, only a couple autolands (dozens in the sim though).

Thanks for links, some interesting read there
