Hades,. .. .Just to add a bit more to Moleslayer's message. . .. .As he said you can either type in a point to go direct to, or you can bring a waypoint on the legs page to the top of page 1 and this will then go direct to this point (I'm talking Boeing so maybe a 'Bus person will help if it's any different). With most aircraft, when a wpt is brought to 'the top' an 'abeams' option is given. If accepted this will then create wpts along your new direct route abeam the original wpts. So if your original route went a,b,c,d and you were cleared direct a to d then abeam b & c would appear on the straight line between a and d. Hope I heaven't caused confusion. So if one is cleared direct Timba and presses abeams then Bexil's abeam will remain on the route. Unfortunately they normally drop any restrictions, so the pilot would have to put back the FL150 restriction on the 'new' abeam Bexil wpt.. .. .It's not a difficult job to put back wpts. They can either be typed back to their original place or one can pop them in a 'fix' page. With this option they then appear on the map with a green circle round them. One can select abeam the fix and then put this position back into the legs page. It's more logical than it sounds.. .. .So, overall, no it's not difficult but it may take a few seconds sometimes to type in. Due allowance should be made when asking us to route back to original point <img border="0" title="" alt="[Wink]" src="wink.gif" /> . .. .As far as speeds are concerned the kit will do the speed reduction for you, so long as you're in VNAV (the 'Bus people prefer to be 'managed'). With this engaged the autopilot will fly the vertical profile you've 'attached' to the wpts, so long as ATC let you descend (or ascend). So if we were told to leave FL350 when ready and be at Bexil at 250 kts and FL150, so long as we were actually cleared to descend to FL150 or below then the machine will do it. If we were only cleared to FL200 then this would go into the mode control panel and the autopilot would level the aircraft at FL200. If it's taken out of VNAV, then pilot is basically doing it all him/herself.. .. .BA still run famil courses for ATC so try and get on a flight. All will be explained much more easily when you can see the kit in action <img border="0" title="" alt="[Razz]" src="tongue.gif" /> . .. .And...... .. .Recover
