Low Drag ILS approach RYR
I have got an outdated Ryanair's FCOM for my PMDG 737 NGX
on this chapter and picture, is the A/C approaching the ILS or Localizer at the standard distance of roughly 10nm from touchdown? or is it infact intercepting the ILS at about 1200ft... https://www.dropbox.com/s/14kjzbd5cg...%2013.png?dl=0 |
What is the difference with a Low Drag ILS APP and a CAT I single channel manual approach
If i stand correct a CAT I ILS APP can also be a low drag - During a CAT I ILS, the standard is to use low drag techniques, meaning that you will delay flap and gear extension to optimise performance and noise characteristics. |
Ryanair's FCOM also mentions this
Landing Procedure Single Channel or Manual - Pilot Flying and Pilot Monitoring < RYR > At 4nm, but not later than 3.5nm, call “GEAR DOWN”, “FLAPS 15." Arm speed brake and check green light illuminated. Call “LANDING CHECKLIST DOWN TO FLAPS.” At glide slope capture, verify proper mode annunciation, check N1 reference bug at the go–around limit and verify missed approach altitude set. is this referring to the FAF - glideslope intercept or from touchdown? I thought glide slope capture would happen before 4nm... thanks guys just need these things cleared up. much appreacited, vernon. |
Sounds like two separate points to me.
4nm from touchdown gear f15 glide slope capture verify [...] not necessarily in order. |
Thanks for the reply.
Thats what got me confused |

Thanks for the response!
Also for CAT I Minima is RVR 550m and DA200 AGL Does cloud ceiling become a factor or is this just for NPA and VISUAL app? |
Only RVR for ILS unless the approach states ceiling required.
|
|
single crew can also go down to 550m with a coupled auto pilot.

Thanks!
Talking about approaches. I was looking at the minimums at LFLB, ILS rwy 18 and each one has a % next to it. Now this means the approach climb gradient and there is a few to choose from like, 2.0% 2.5% 3.0% etc. how can i work out what is for my AC? |
You need to get into the performance part of the flight manual and work it out. The FCOM may have some simplified information to make it easier.
Chances are some one at your airline has already done this, so ask around. Try your performance department. |
I don't work for an airline. So this sort of thing is going to be hard for me!
|
If you are flight simming, just use the lowest minima with highest missed approach gradient.
|
Yeh i used 1690ft as the minima. Think that was about 5% for rwy 36
Also how can i work out for a given speed over a certain distance, on when to turn downwind? Example : Fly the ILS approach on heading 176 and at point A turn left to point B on heading 135 for 2.6nm. Then turn right for downwind for xxnm How can i work out those distances to fly in seconds? So when i turn at those points i start my stop watch. Speed is 150kts max so gear down f25-30 at this point. I do have other visual aids like the highway A43 that pilots use for this approach, because i have european roads added to my flight sim. Thanks!! |
Do you have a link to the approach plate you are referring to?

Dropbox link isn't working

That's a special approach! In real life I'd be flying it visually during the day. Unfortunately a visual circuit is one of the harder things to do in a sim due to the lack of peripheral vision. At 150 knots you travel 2.5 NM per minute, but you also need to allow for the radius of turn. You could program some RNAV waypoints and follow those.
