Hi guys

 

I am getting a bit confused by all the different SAU modes and when to Use it.

So we have directional , automatic, stabilize and recovery. I read the manual but I am still confused about the first third ones

 

Lets say I am 100Km from my Airbase over the clouds:

 

I first set RSBN and PMGR station channel, set the course, set the switch to cloud penetration.

 

Which SAU mode should I engage so that the autopilot get the right sink rate? Or Do I have to use directional and adjust myself the stick?

 

Under the clouds, I then set the switch in middle position, which SAU mod will enable me change my position If I went off-course?

 

What is the difference between directional and stabilize exactly?

 

Once the PMRG signal is acquired and G , K flags are not red anymore , I can activate SAU auto for AP approach , disconnecting a few hundreds meter before the Runway threshold.

 

 

Thanks :pilotfly:

No help from SAU during cloud penetration, You have to adjust descent rate (watching needle on KPP) and glideslope (needle on NPP) yourself.

 

Which mode to use on final approach? That depends on Your preferences. In auto mode the AP will control roll and pitch of the airplane to put it on the correct glidepath (assuming PRMG signals have been intercepted, obviously). You only control thrust, flaps and gear then. In directional mode You have full control, but the AP gives You "landing tips" via yellow needles on KPP. So it's not much different than "manual" landing without SAU (just different instrument and needles to watch).

 

In my opinion, both modes are not really useful - the auto one has serious accuracy issues on some airbases, while in directional one you still have to fly the plane yourself, so why bother turning it on.

 

Stabilization mode is supposed to smooth out the control inputs and/or stabilize the chosen pitch/bank attitude of Your airplane, but I've never tested how well it's doing its job.

This is all correct.

 

Just flying PRMG is much easier than faffing around with the SAU in my opinion.

 

And if you miss the approach just fly a big box - being careful not to collide with the ground eg at Nalchick. Where you know there's terrain nearby would suggest turning on rad alt warning to eg, 100m and leaving gear up until you're confident you're clear or terrain.

 

One feature that would be REALLY useful would be ATIS at airfield with QFE and weather. Or failing ATIS the ability to ask ATC for QFE and weather info. At the moment it's a bit of guessing until you get final approach clearance!

Night approach, heavy rain and fog at 100m altitude?

Just do it yourself!

It's still the question of watching two needles on an instrument versus... ummm... well... watching two needles on another instrument :D :D :D. Hence my comment.

 

I'll admit however, that yellow needles are a bit longer and thicker than white ones, so from short-sighted fellaz' perspective, You might have a point ;).
