Мне в слепой посадке одно не понятно:
Как узнать курс полосы, если как только на курсо-глиссадке я его поймаю, он тут же убегает?

Учиться:

Thats a technique problem that is as real in real life and is a typical student Instrument flying error Attempts to dynamically track the AFN2 centre needle will result in out of control "slash" attacks on the Lorenz centreline and never quite catching it. If you use the right tecnique it works exceptionally well. So how do you do it ?

1. Know the exact Lorenz inbound course (QDM) EXACTLY
2. Set the Patin compass heading to the QDM EXACTLY (concentrating on the compass not the AFN2)
3. Get the aircraft configured for the approach early, Speed, Power,Gear and flap and TRIM (minimise power/Torque) changes
4. Intercept the Lorenz course and fly the QDM heading EXACTLY
5. If you drift off then make a SMALL (like 2 deg max) Heading change to intercept the course.
6. Just nanofart before it recentres turn back to the QDM.
7. If crosswind is present then you need to allow for that as well .. but again we are talking about small numbers.

Notes:
Setting up the Patin compass to the Lorenz inbound course is essential as you always have a datum then.
Catch deviations early. Only use about 2 degree heading changes. Only use a max of say 5 degrees Angle of bank to make the heading change (even less might be better). You must be slow and methodical. Make an adjustment and give it a second or so to see if the change is happening. If its not quick enough for your liking (careful) then maybe add 1 more degree to the correction. Then as you are just about on course smoothly turn back to get the Patin compass needle vertical. Throughout the approach 80% of your attention should be given to the Artificial Horizon 15% for the patin compass with the other 5% to the AFN2 to check on how things are going. Concentrating on the AFN2 needle rather than HEADING will lead to frustration and sloppy Instrument flying..... Be smooth be patient be cool

Also know how to fly a heading ! Firstly you must be trimmed out If you let go the controls and any flight parameter changes you just arn't trimmed ! A constant heading is flown by being Wings level (EXACTLY) and in balanced flight. 1 degree angle of bank on approach will rapidly result in moving off the course. Use both the Aircraft symbol and the Horizon line and the AH sky pointer to fly exact wings level.

TRIM TRIM TRIM TRIM .....Its the meaning of life

Mission Builders should provide the exact QDM for each Lorenz station in the Mission description. This is Real world published data. Without it it makes it very very difficult to fly the approach !
