Basic ILS technique.
even before starting the ILS, know the following:
initial rate of descent is approximately 5 times your groundspeed in knots...Apch groundspeed 140 knots...your initial descent rate 700 fpm...make your calculation in advance. 600 to 700 fpm for most jets to start.
consider the winds aloft , its effect on heading required to make good the localizer and how they will change as you get closer to the ground. within 300 feet of the ground the winds change (also at base of clouds if defined based exists)...they swing to closer to what the tower reports.
step one:select course, tune and identify the ILS freq, make sure beacon receivers are on HIGH
Intercept localizer and make a good guess as to the heading required to maintain. split your scan between the needles and the basic flight instruments...don't chase the needles, try for the heading making refinements as you go
as the glideslope needle comes alive, configure the aircraft for landing so that by the time you are ON GLIDESLOPE, you are fully configured for landing and stable in your 600-700fpm descent...TRIM and set the power.
now, monitor your heading and descent (airspeed too) as your marker beacon starts to sound, select norm or llow.
when the marker beacon sounds again, OM, start your time in case you lose the glideslope, you could ocontinue with the localizer only apch....you do not need to TIME to the missed apch point if ONLY considering the ILS as DH is your missed apch point.
monitor and fly the apch, making small refinements if a calm day...on a rough day you will have to be MORE on top of things...as you apch DH adjust your heading to compensate for reported winds on the ground...also your rate of descent may slightly be reduced to maintain glideslope. AT DH, have your copilot tell you if he can see the 11 required items to continue, if he has them in sight, look up, adjust and scan between outside and inside as you acclimate to looking out the window...have copilot call speed and rate of descent to touchdown.
