Check the approach charts for the runway you are landing on to see the glideslope intercept altitude as well as near what waypoint it is captured.įor example, if you take a look at this ( ) chart for an ILS approach for runway 27 at KIAH, it has a helpful visual representation of what altitudes you should be at when you reach certain waypoints. As far as I know, the most companies SOP doesn't allow fly the airplane without Flight Directors except for raw data ILS and recycle on final app.I don't know how the QW 757 works, but in the PMDG 777, I follow the STAR towards the runway, engage the localizer, and then at around 2000 feet and less than 10 miles away from the runway, the glideslope is usually captured. It is very important especially when you flying night and IMC conditions. So now, you can fly the airplane with correct FD guidance and later I would communicate with about missed approach procedure. then select proper roll mode and pitch mode, retract gear and flaps as scheduled When you did it, app mode will disengage and plane will revert CWS R and P modes. But in this case, the GA altitude is below current altitude so it is not correct. so there are two option:īut when you press TO/GA, it will always show you to ''pitch up'' command. Because, as you said, you can't disangage the APP mode after it was engaged even if you push app or recycle the F/D's. Really good answer but you missed that this question exactly for 737NG.

Other times, the turn towards a holding patern is immediate after the missed approach point. Usually, but not always, the missed approach procedures begin with maintaining runway heading after the missed approach point until a certain fix or radio-navigation aid (VOR/NDB) or radial and distance, and then turn towards a holding patern. In this precise case, I understand your machine was configured to use the autopilot to intercept and follow the localizer and glidepath (beware that in Europe, when landing is forbidden to keep the autopilot engaged below 500 ft and all pilots are expected to disengage the autopilot at or above 500 ft and always land manually the airplane). In your case, You are expected to set the flight management computer to already know what are the next segments to fly (missed approach in this case). The machine must always be set ready for the next step to do. The instructions of air traffic control supersede everything published, so in your case even if on the chart the missed approach point is indicated at 1500 ft, and the ATC instructs to begin the missed approach procedure, then the pilot is expected to begin the missed approach procedure immediately, not continuing descent to 1500 ft and then start the procedure. Unless the ATC instructs otherwise, the missed approach procedure or any other procedure, should be executed as published (see Jeppesen charts, or the ones in the AIP). First of all: your question is independent of aircraft type, Boeing, Airbus, Cessna or whatever other aircraft one is flying is irrelevant.
