Hi Does anybody have experience of using the ILS? Using Brize Norton as my airfield I am testing the ILS system and find that the Track seems to give reasonable results, but the Glide Slope seems to be non functioning: I get the green VLOC indicator on the HSI and (with some difficulty) can stabilize the aircraft at about 110 knots with flaps and U/C and can fly more or less horizontally into the G/S. Having done all of that she seems to ignore the glide slope instrumentation and either drop below or rise above the "needles". I can correct this to a certain extent with the throttles but that seems to defeat the object of the instrument. Does anyone have any thoughts? Best regards Mike

I can't do it either. I was using 23R at EGCC.
From what I can gather, establishing a stable approach speed was very important on the Canberra before engaging the GLIDE mode. The numbers are vital. For example, I was approaching on low tanks with the flaps down & the trim fully nose down, and the aircraft would only stop pitching up when the speed dropped to around 110 kts, with throttle at around 70% as stated in the manual. This is consistent with the chart on page 29 of the operating data manual. Then I engaged GLIDE but it overshot the glideslope. I used slew mode to move the aircraft back several times to re-attempt it but it wouldn't capture. Like you I could easily correct it with the throttles, but as you say, that defeats the purpose of having a GLIDE mode. One might as well fly it in manually. Are you using it with FSX or P3D? |

Hi Jason
I am using FSX Steam. I agree with all of your points - I have been guilty of flying too fast on the approach and I have learnt to disconnect the elevators from the autopilot before lowering the flaps (the Dive / Climb switch is not responsive enough to prevent a rollercoaster ride when the elevators are connected). I have mentioned the difficulty in locking onto the glide slope in a Technical Query that I raised on another matter. But because it was a secondary point I do not know whether Just Flight will follow it up at all. Now that I know that I am not the only person struggling I might mention it again to Simon at Just Flight. Otherwise I am very impressed with the 'plane and have a lot of fun with it. All the best Mike |

Hi Mike
I was wondering if it might be a P3Dv3 problem, but it would seem not as you are using FSX-SE. I'm not giving up yet - I'm going to try out a few other things, and if I can't get it to work I shall also log a technical query. I agree it is an excellent add-on - definitely ranking with the best available. All best to you also! Jason |

Hi Mike
Further testing has revealed to me that GLIDE hold, when activated, does in fact operate the elevator trim. When engaged, I could see the elevator position indicators fluctuating. /Jason |

That is good news indeed! I will try this myself as soon as I can. Mike |
