I try to find out what is the best speed to capture a LOC/G/S . Also is it possible that when approaching too fast that the LOC/G/S cannot get captured ?Thanks for your infoHerbert Werni

I would say between 180 to 200 knots.Important other parameters are the intercept angle and altitude.The g/s should always be intercepted below the g/s altitude.Approaching at a horizontal angle of greater than 30 degrees at highspeedcan result in the aircraft zig zaging down the slope and making a rough landing.Note on this aircraft on autoland,the align light comes on just prior to touchdown.Also,pay attention to crosswinds.Excessive crosswinds can negate autolanding as it may exceed specs.If you are using a STAR approach,it will generally set you in the right neighbourhood.Ron Service

Up to 220 should be just fine.

Most airport charts indicate a maximum of 180ias when establishing with the localiser and glideslope. Unfortunately the sim atc is lacking in separation control so you have to be a responsible pilot and adjust your speed accordingly.250kts at or below FL100 - 230kts in a holding pattern - from the holding pattern 210kts - descending to faf 180kts - outer mkr 140kts - vat (dependant on a/c weight)vololiberista

140 KIAS on the outer marker is very slow. I'll use EPWA TMA as an example; vectoring speed is 220 and there's a speed restriction of 160 KIAS and above until 4 miles from the localizer. It of course depends on the aircraft capabilities (you won't get to hold 220 in an ATR).
