Donny AKA ShalomarFly 2 ROCKS!!!When preparing a flight plan to an airport without an ILS after all waypoints have been created I zoom in on the destination airport till all runways become visible. This usually first happens when the range from top to bottom is about seven miles. I create another waypoint 6-7 miles from the destination runway that lines up closely with runway heading (as shown by the red line). Since the airport waypoint centers on midfield I zoom in much closer and place a waypoint at my plannned touchdown point. I cross the 6-7 mile waypoint at 2000' AGL. I then do the following calculation for a 3 to 1 glideslope: Take groundspeed (easily found on GPS), drop the last digit, divide by half 90 kts= 9= 4.5 and move the decimal point two places to the right. Thus my descent rate should be 450 FPM if I ramain at 90 knots. This trick also works well for descents from cruise. 250 knots= 25= 2500 FPM descent to acheive 3 to 1 glide slope. Of course when I get closer I look at VASI if available and try to keep the runway at the same spot in my windshield. If it starts to rise I am too low and if it lowers I am high.ATTENTION KEN: This method would work much better if I could use the OBS feature and reduce CDI scale sensitivity but I can't. Are these TRI bugs or am I doing something wrong???:-wave

G'day Donny,A 3 to 1 glideslope ?? Where are you getting this figure from? A typical glideslope is only 3 degrees. I haven't got a set of trig tables handy so I can't give an exact gradient.450 ft per min @ 90 kts = 1 in 20.27 glideslope. Your second example has a math error; should be 1250 ft./min.250 kts = 25 = 12.5 = 1250 ft per min. = 1 in 20.27 glideslope.Whilst having a simple rule of thumb is great for general purpose flying work it is not really going to cut the mustard when it comes to precision appproaches. After all, that's why ILS came into existance in the first place!If the runway has a localiser (but no ILS) then sure you could use the AP to capture the localiser (runway heading) and your rule of thumb to manually control the descent. Just allow reasonable minimums as there will almost certainly be a bit of adjustment required (using the VASI lights) on short final.Cheers,Roger

G'day Donny,> This method would work much better if I could>use the OBS feature and reduce CDI scale sensitivity but I>can't.

The CDI scale sensitivity in this instrument is selectable to either 5nm , 1nm , or 0.3 nm Cheers,Roger

For 3 to one, I meant traveling 3 miles for every 1,000 feet of altitude loss. I'll try out the CDI on the Cessna.Thanx.:-wave

hello!sorry for my bad english. i have a big fly!2 problem. after starting fly!2 and choose the graphik options, the screen flicker substantial. Only when i choose directx7 there is no flicker. but then, the frames and the graphik is very very bad.i have fly!2 version 2.5.240i use winxp sp2 with an ati x1600 graphik cardthank you for helping me!
