kilo- miles per hour...

Sub-jetstream = An unusual meteorological event resulting in extreme lower level winds!...

...apparently its turbulent.. thats what they said when we entered the jetstreams above japan.
Would you guys stop baiting the young folk.
They have initial Class One medicals to get through ...

Thanks Capt.
Where do you live anyway? I might pop over with a carton of eggs!

Groundspeed

My A320 feels like a Cessna 120 compared to you guys. wow 700plus knots! I give up! Tried to catch at least 600knots gs 2 nights ago but came up waaay short. Maybe when my employer gets a 777 and fly trans-pacific i'll get to post a worthy pic.

Anyways Doc, how did your Bonanza get that fast?

"Anyways Doc, how did your Bonanza get that fast?"

thrust clb - if you look back through the posts you'll see that I did explain it (sub-jetstream!). Was just having a bit of fun to illustrate that all may not be quite as it seems. I ran a GPS simulator program on the tablet computer that has my FliteDeck moving map program, and set the waypoints for YLRE - YBTL with a GS of 842 kts - and then took a pic of it.

I later did it again with the GS set to 10,000 kts - man does that cover some country!

To date the best GS I have had in the V35B is 204 kts on descent into Cairns last year. I was about to pull out and pass a Dash 8 when ATC noticed the rate of closure - and vectored me out to sea!

Now i get it! thanks! I remembered when i was flying in General Aviation, the first 200knot GS aircraft i flew was a Cessna P-210 (Pressurized Centurion), that's what it shows during descent. In cruise it does 175 GS. ATC always thinks i'm in a Baron.

One windy day I had an A36 up to 217 knots.. in cruise, from Port Lincoln over to Adelaide. Had almost 60knots directly on the tail.

Niiiiice.

G/S

As my name suggests, I used to be an F-111 pilot, Highest I have seen is 1405 Knots G/S Groundspeed (One Thousand Four Hundres and Five Kts G/S).....and yes it was at Flight Level 490...

...seen 705 Kts G/S at 100' Above the Water.


oh yes those were the days.

Out of Jandakot heading for Kalgoolie, September 2006 in a C402, saw 226 kts GS but only for about 1/3 of the way.

The rest of the flight to Alice Springs was much slower.

And they paid you as well to have that much fun.

How slow can you go?

There's a number of posts above regarding how fast one might go, so here's something at the other end of the scale. Taken whilst flying straight and level at a constant airspeed of 38kt IAS. One needle width slower and the nose pitches down with the old girl rolling gently off onto the left wing. If you can wind it back any slower, let's see it.

Used to drop meatbombs from a nice little 182 that would indicate about seven or eight knots below the bottom of the green arc, and still hold height perfectly well. Never got a groundspeed check - the only time I used the GPS was on my first day.

(The mad Dr bends down and picks the object up)

Yes, it is indeed a gauntlet - thrown down by a Pickled Parrot!

Had a negative ground speed many years ago, landed a sailplane into seabreeze and rolled backwards about 15-20 feet !

PLovett, it's not uncommon to get 250kts GS in a C402 or C310 between JT and KG during winter with a BIG cold front pushing you along.

As you said, the first 1/3 is the best, also the most turbulent. I'll have to work out how to get the photo from phone to computer.

Saw 194kts in the cruise in a C206 a few years back. Surfing a cold front from Broken Hill to Cootamundra.

Will try to beat the low speed record this weekend in the Tiger. Hang her on the prop and i reckon 30kt IAS should be do-able. Will take a camera!
