I live on a flight path to Gatwick airport , i would guess its about 10 miles away . How fast would the aircraft be going ,coming in to land ? I can see the aircraft flick on their landing lights 2 1/2 – 2 3/4 mins before they go over my house . Trying to work out how far away they would be when i first see them !

It's a calculated value based on aircraft weight among other factors; generally in the range 120-150 knots.

If you have a smartphone get the app Flightradar24. It shows all details of all aircraft in the area, including height, speed etc. It even shows what the ground looks like underneath the selected aircraft.

Usual call for the sort of aircraft you are looking at would be "160 to the marker". That's maintain 160 knots until the Outer Marker (a fixed reference point indicated by a radio beacon). Once past the marker, speed can be adjusted to whatever is type specific for the final approach. The landing lights come on with gear down selection and that, again, is usually at a standard point in the pattern – so, for instance, the 747 would usually hold 210 knots (Air Traffic dependent) until coming up on the final turn and then the call is "Gear down, Flap 20 , Landing Checks". That's how it was when I was 'in the business' but I doubt things will have changed much since then.

While not an aircraft enthusiast, I occasionally visit this part of the forum if I see an interesting post.

It occurred to me that those regularly posting on this topic might be interested in two books I have in my collection which I am willing to give away.

One is a guide to the Moorabbin Air Museum in Melbourne which I obtained on a visit about 20 years ago. It is a 24-page A5 size soft cover booklet with each page containing a b&w picture and half a page of info on each item.

The other is a 72-page B5 size soft-cover b&w picture book of all aircraft used by the RAAF since its formation in 1921. It has pictures only with 2 pictures per page, no info on each plane other than the make and model. It is undated but the last entry is the Phantom F4E which would give some idea of the date.

Anyone interested please send me a message. I am in Brisbane Australia if you are wondering.

Hacksaw – interesting photo. I have to admit that. even having been in 'the business' for close to 50 years, I have never actually seen a marker beacon. If that is what is shown, it would mean that every approach to the runway that it relates to would pass directly overhead. It does, however look like a standard VOR installation – (more an area nav. than approach aid). Could, of course be co-located but very unusual, if so.

A bit of Googling produced this …

I don't have Aeronautical charts to hand nowadays, but would your daughter's place be somewhere near Mayfield?? There is/was a Gatwick routing VOR identifier MAY.

That's what I though too, but didn't like to put my foot in it just in case it wasn't. I'd always assumed that marker beacons were essentially Yagi-like directional antennas on poles on the extended runway centreline.

I'm not aware of any co-located VORs and markers, although VORs are often co-located with DME. The Mayfield VOR is still there on my current half million chart.

I'll plead ignorance.. I was only told it was an aircraft beacon for Gatwick ! Few miles from Mayfield , it's at High Hurstwood perrymans lane .

Word " Doppler " was mentioned?

If I stood under it with a strip light, would it light up ? Will the horses get tumours? It certainly helps rabbits breed , there's lots of them…

Probably not, because the suspended grid is a grounded counterpoise to the radiating antennas.

Doppler VOR is more accurate than normal VOR due to better handling of spurious reflections, but is rather more complex electronically.

An Electricaly powered Aircraft has been developed by Siemens, it was featured on the BBC News this morning.

Two seats and apparently rechargeable with something like 30 minutes flying time.

I have linked here to the video of the reporter taking a flight.

Now that screams for a "Hybrid" conversion. Nowt like a bit of back up having just watched out of my kitchen window a diesel powered fork lift pushing an electric (or not) powered version. Hope there's a decent fire blanket wrapped round the A/C battery, look what problems Boeing had with Lithium batteries and Hammy was lucky with his latest escapade.

Regards Ian.

Yes I think the actual original item I saw on the news mentioned hybrid possibilities.

Siemens seem to be very active in the field of electric aircraft propulsion, I have been doing a little research since seeing the item and have come up with a new link to Siemens for this. I found it very interesting.

I guess those plug in battery packs on the news item might have other possibilities who knows, electric vehicles?

The icon used to represent the Airlander in the NATS application ticked my sense of humour… A large, twin-engine aircraft flying around Bedfordshire at 19 knots?

Hacksaw, what is that people with horses have against rabbits? A lady at work who has horses keeps pestering me to go around and shoot them where the horses are, do they carry infections or something? Sorry for going off topic, so Jaguar GR1 used to land at 160-200 depending on config.

Dr Dave,

Was that track today, I've been home all day and it passed close by to my village and I didn't see or hear anything.

Martin,

Yes, the"Flying Bum" was out this evening from about 6 to 8 pm. Compared with some airships, the Airlander is quiet.

Ian, the rabbits dig holes and the horses can break a leg if they step in one.

Rabbits are delicious in pies, although apparently some people prefer stew.

The little b*ggers delight in undermining the support pilars at out track. We used to have a chap with a ferret who came and reduced their numbers every now and again, but no longer I fear.
