Ajajay Skybound!!

Let me explain! If my normal cruising speed in a headwind is 70km/h, with the fairing it's now 65km/h. And with a tailwind normal is 100km/h it's now 110km/h!!!!

Hope this explains it better!! :D :D

Got You some more information via Hazzard

The one guy that has bought an aircraft is 6"41/2" and he fits in without any discomfort as Ive built this aircraft.

The next guy that came round was 6'6" and only had 1" spare between he's head and the top boom bar.

We have looked into this and can lower the seat by 3" if we take the rear control column out and can lower the seat by 2" if we change the type of elevator push-rod, which would give the 6'6" guy a 3" clearance from he's head to the boom bar.

Apparently should one need some more elbow space one can build swell doors which bubble out a bit.

1) All the prices are on the www.cgsaviation.com in US$ and have most prices attached

We have only freight, agents, and crating fees added on to those prices, which is dependant on the exchange rate used at the time of purchase.

Airframe and covering U.S $ 13237 R83394.00

Engine mount for 582 Rotax U.S $ 175 R1103.00

Wing tanks If Required U.S $ 424 R2672.00

USA Packing U.S $ 300 R1890.00

Freight and Agent fees Rands R11179.00



Total needed to get flying is R95676.00 and a bit of work if you supply the 582 and instrumentation from your trike.

I am missing you somewhere. Not sure what you are referring to as cruising speed. Most mean air speed when using that term.

Air speed is air speed irrespective of tail or headwinds. Your airspeed, given a set trim will never change irrespective of where the wind blows from. You will always travel through the air at the same constant speed. The only variable is ground speed and that will be determined by the wind strength and direction.

I think you are saying that you may have lost a bit of air speed by fitting the fairing. This loss in airspeed will be equal whether travelling into a headwind or travelling with a tailwind. Your aircraft does not know if you are flying headwinds or tailwinds.

[Smiley]

Ground Speed changes.

Airspeed
Your airspeed can definitely also change! If you have a headwind your airspeed increase and groundspeed decrease, and visa versa!

This is the way you determine the windspeed while in the air.

Scenario
Flying "north" you encounter a headwind. Let's say your airspeed indicator shows 95km/h and the GPS grounspeed shows 80km/h. Thus a headwind of 15km/h!!

Flying back "south" you will find in the same conditions your airspeed will show 80km/h and grounspeed will be 95km/h which means you have a tailwind now of 15 km/h!!

Airspeed will never be constant, it's always relative to the wind!!

Semantics boys, semantics

Actually Smiley, SkyboundER is right. If your plane cruises at 65mph with a certain throttle setting your indicated airspeed IAS will show 65mph irrespective whether there is a moerse headwind, no wind or a tailwind. What will be different will be your ground-speed. An increase in headwind cannot increase your IAS. Turbulent conditions or gusting will temporarily show as an increase or decrease in IAS, however if the wind increased from 10 to 25mph headwind and then stayed there the IAS will show 65mph, but the GS will decrease from 55 to 40mph

However the addition of the fairing has introduced a level of drag which is why your previous cruise speed was 70 and is now only 65. This could be due to the extra weight or the design. I would have thought the addition of a fairing would streamline the plane and reduce the mechanical drag, thus giving you better performance.

Helolo friends in flying :D :D

After speaking to a couple of pilots I understand your comments! Oops, sorry, I wasn't thinking.

Please find a place in your hearts to forgive me!!

No forgiveness necessary. I can guarantee you that there will be others to confuse airspeed and groundspeed.

Recall a few years back that there was a moerse debate on the SAMicro list where even some experienced pilots that got the two confused. Was a debate about landings.

When you are in the air, you are IN it, you can not move faster or slower in IT at the same trim, no matter headwind or tailwind; you are IN it and move relative to it. I know our perceptions might fool us.

There is also the related myth and old dreaded down wind, base leg stall problem that "old" pilots talk about: "Watch out for it when coming in to land in a strong headwind!" :D . The difference of flying downwind and then turning into it, somehow miraculously causing the aircraft to stall. It is just our perception relative to ground that plays with our minds...

PS: That said it also sometime seem to me that I fly slower/faster than other aircraft in the group depending on head wind/ tail wind. But who knows what the other pilot is doing at that time of my evaluation.

[Bennie Vorster]

Aa Ha, got a faring second-hand from my friend Rene in Newcastle. He still has some spares left of a Laser XR that he is breaking up to sell bit by bit.

No accident Damage. And at R1500.00 it was a barging. I think

Two trikes groundspeeds can differ depending on the difference in their individual aerodinamics and therefore the slicker of the two's groundspeed will be faster traveling into a headwind

I hope I haven't opened the debate again

I once heard that polishing the bars on a trike actually makes it slower - told the Golf ball effect. This came from a instructor a few years back, was he yanking my chain? He also mentioned the rougher the bars the better. Logically to me slicker and smoother would be better, but after reading some history about the golf ball and WW2, I dunno also I'm vaguely aware that before competitions some pilots polish their planes...

From what I understand it has got to do with the shape of the object in question, round bar = rough, pod larger so = smooth? I've seen on some trikes the bars tend to be oval, thus lengthening the airflow, so it needn't be rough?

Someone in the know care to comment?

[Smiley]

I know the cleaner the surface, the cleaner the airfoil!! Thus less drag and a lower stall speed, if you look at the wing!

[PMarshall]

Smiley- Airspeed is the speed that the craft is travelling through the air. So if you have a craft that is a bit more slipery it will have a higher airspeed than the craft with higher drag. Groundspeed is only a vector of airspeed. Performance of an aircraft is always measured in airspeed. Groundspeed is only relevant for navigation. A gps can only give us ground speed so can only be used for navigation. An airspeed indicator by itself can not be used for navigation by itself without a lot of calculations. Thank goodness for the GPS

Keep Well

Yip, that's what I was trying to explain, the more aerodinamic of the two trikes will be faster.
