Re: Twin Otter - prop lever usage?

Right, thank you. Only thing is, there's a mixture of terms being used: 'high'/forward'/'back'/'coarse'/'low'/'fine', but I think I see your meaning! Throttles and props in turbines is not like in pistons. Props set high rpm for flight, low for ground, line up go to high rpm, clear the runway, go lo...

Re: Twin Otter - prop lever usage?

Search is your friend... Rarely my friend - I spent half the evening looking around (the internet generally) with not quite the results I was looking for. That thread did not come up within that time... Thank you, I'll read it carefully, though at first glance most of it seems to describe the theor...

Twin Otter - prop lever usage?

Would anyone be able to explain to me, please, the 'normal' usage of the prop levers during a 'normal' flight... that is, how they are usually positioned by pilots, (course/fine), at engine start, taxi, takeoff, climb, cruise, descent and so forth...? I have watched a few videos explaining the techn...

Re: Concorde & engine startup?

"the logistics and safety precautions of moving a GPU and two Airstarts out onto the taxiway is something I would not like to see." No, I didn't really think this was an option! :-) So you would start all four engines before pushback? I imagined the most likely scenario would be pushback w...

Concorde & engine startup?

I think I once knew this, but am now confused (trying out the amazing new Concorde in X-Plane!). So maybe someone can help. Can Concorde start its engines without a GPU (there being no APU)? Assuming not (if so, how?), do - or, I should say, did :( - the pilots therefore have to start up one (or was...

Re: When is the A/P disengaged on landing?

Thank you very much. I have certainly seen some nonsense (on some other forums) on this subject, as I suspected.

When is the A/P disengaged on landing?

OK, assuming we are not switching of the autopilot 'early' to hand fly to the runway, at what point would a pilot disengage the A/P for a full autoland? Perhaps there are options, but according to videos I have seen the A/P is often switched off a short time after the nosegear is on the ground.Seem ...

Re: Question re. Antonov An-148

I did try that - there doesn't seem to be a 'push' function though, in the JD aircraft at least. Thanks.

Re: Question re. Antonov An-148

There is a switch NAV1/NAV2/GPS, which suggests that there must be a way to set LNAV and switch it to ILS at arrival, but there is no NAV button per se, at least in the JarDesign incarnation of the aircraft - which does seem to be the same as the few pictures of the cockpit I have found, though as w...

Question re. Antonov An-148

Anyone know how this a/c engages its lateral mode (LNAV)? I haven't been able to find a close-up photo quite detailed enough to confirm, but although there is a VNAV button on the MCP, I am pretty sure, I don't see one for LNAV. Similarly, one incarnation of this aircraft for X-Plane has no LNAV fun...

Re: Remember Dave Allen?

Grew up watching Dave Allen, greatly missed.

Remember Dave Allen?

Not sure which forum this might go into, but I'll post the link here: it might amuse some of you!

Re: Why are the APU GEN & APU BLEED usually left on?

Re. the 737 that's what I had expected (from what I have seen): thanks for the confirmation.

Re: Why are the APU GEN & APU BLEED usually left on?

Thanks a lot for the replies. Flying 'training level' aircraft in X-Plane 11 (in particular the ToLiss a319 and the FF B767) I am trying to get this as near to the 'real thing' as I can! I have long appreciated the different ways that Airbuses and Boeings deal with these things - the Boeings, in gen...

Why are the APU GEN & APU BLEED usually left on?

The title says it all, more or less! Why do these switches tend to be left on for the whole flight (certainly in all the real-world cockpit videos I have seen), even though the APU itself has been turned off after engine startup? Is there a difference between Airbus and Boeing general practice in th...

Re: No 07L/25R EDDF Procedures?

Hi.. thanks. Yes, you're right about the SIDs of course, I had forgotten that it's a landing only runway!

No 07L/25R EDDF Procedures?

Just wondering if anyone knows why runway 07L/25R at Frankfurt has none at all (SIDs/STARs, that is), whilst the others, 07C/25C & 07R/25L have many.

Re: Flight numbers?

Hi .. I had always taken it that it is the IATA code that would be used in the FMC (just to stick with that example of the usage I am talking about - not ticketing, callsigns and so on), but maybe not then. So for flight BA238, BAW29G, not BAW238 would be the flight number entered into the FMC. I su...

Flight numbers?

I realised just now that something I had taken for granted I was familiar with is, now I think about it, not as clear in my head as I thought, so may I ask.... What prefix does ATC (and the pilots) use to identify their flight number. I am not talking about their callsign... For instance, British Ai...

Tsaradia DHC-6?

Is anyone more able than I have been to trace information about Tsaradia's Twin Otters? Are they in their own livery, or Air Madagascar's? (The ATR's have their own livery, with the lemur - very nice). Any real-world photos? Looking for reg numbers too - I think they use Air Madagascar's a/c? Thanks...

Re: B737 - normal use of DC power knob?

OK... I'll watch that video more fully when I have a moment (half an hour or whatever it is)... Maybe the other questions I had will be answered there. Thanks.

Re: B737 - normal use of DC power knob?

Moving the knob to different positions does not alter anything on the airplane itself, the selector just picks up the DC voltage from the selected bus and indicates the voltage on the display above the knob. That rings a very loud bell in my head (and I feel a bit daft for having asked the question...

Re: B737 - normal use of DC power knob?

... I didn't phrase some of the last part quite correctly. Given that Standby DC power comes via either the GPU or the APU, under what circumstances would the selector be moved to other positions (like BAT)?

B737 - normal use of DC power knob?

I am looking at the 737-400, but I guess that 737NG are the same in this respect (?) I'd firstly like to ask what the functions of the various positions of the DC knob on the O/H panel actually are (STBY PWR; BAT BUS; BAT; TR1; TR2; TR3 & TEST). When would each of those positions be selected by ...

Re: Max speed while banking?

OK, that's clear. The SID I enter into the FMS doesn't have this elevation restriction, so the a/c accelerates after FL100 of course (the a319 climbs quite powerfully when I engage CLB and has reached that altitude before D313H).. I need to enter this manually I think (and yes, probably a speed rest...

Re: Max speed while banking?

One example - the SID SSN2C out of LEBB - the a/c I am flying (an a319 here) has no chance of making the tight 180-degree turn at D313H (it's at 300kts by then). Basically, you folks are saying that, if there are no speed restrictions indicated, then the much wider turn is fine? (In this case it's o...

Re: Max speed while banking?

Haha! Turn, yes, not bank of course. Brain on autopilot again... I was supposedly asking about doing turns at high speed. I suppose if the bank angle is always small, there's no issue. But in the real world, when pilots know that there is a big turn in a SID, especially if the aircraft would be norm...

Max speed while banking?

I often find that I arrive at a sharp turn in my flight plan (or more usually SID with a long first 'leg') when the aircraft (I mean a320/b777 or the like, not c172) has climbed beyond 10000' and, being in CLB/VNAV mode, has already accelerated to 340kts or whatever. (Talking X-Plane here BTW, not p...

Re: Use of GPU to start engines?

Great replies, as so often on these forums. Many thanks for your time and effort... Aircraft is powered by external electrical power ("ground power"). 1. Switch on batteries. Aircraft is now electrically powered from external power. 2. Start APU by using external electrical power. Aircraft...

Re: Use of GPU to start engines?

Thank you for the replies! Yes, for me 'APU' refers to an onboard power unit, and I am familiar with it and its usage. The ground equipment I have always rather taken for granted (in FS9, FSX and now X-Plane) and wanted to understand the various options better. I'll carefully read through what you h...

Re: Use of GPU to start engines?

Thanks... unfortunately, the term 'APU' is confusing me, because here it is referring both to the onboard APU and, apparently, one on the ground. Assuming that for whatever reason the aircarft's own APU is not used immediately and initial setup is done using ground power... I wonder if you could exp...

Use of GPU to start engines?

Could someone kindly explain which ground support equipment is most usually used on jet aircraft? Is the GPU used alone, or in conjunction with a High Pressure Unit.. or can the HPU be used alone?? Is the GPU a gas turbine unit, or a diesel compressor? Googling hasn't really helped, so hope someone ...
