Braking Action Unreliable 17th Mar 2003 09:35

Did 216KT in a Seneca II on IR flying Cardiff - Gloucester, suppose it was first MTW encounter, other than "Meteorology for Pilots" :D

timzsta 4th Apr 2003 04:45

Flew from LAX to LHR as a punter about 15 months ago in a BA747-400. 9 hrs 30 airborne. At one point our groundspeed on the inflight cabin things was 1300km/h (701 kts). St Johns to Lands End in 4 hours.

I saw a programme on the SR 71 recently. This bloke told a story of when they were flying over Libya post the air raids. A SAM was fired at them, they opened the throttle and out run it. No that must have been fast....

Back in the days when I was in the Navy as a "Freddie" I was sat controlling an FRA Falcon target tower in the south coast exercise areas from onboard a Type 42 (real warriors ships, air defenders rule frigate faggots). The Air France concorde made his usual morning appearance".
"Broadway 21, traffic SE, 25 tracks west, high, fast, concorde".
"Traffic in sight, trailing, do you have his groundspeed".
"600 knots".
"We can do that"
"Yeah but you cant get to New York can you"
"We could, it would take two days and a stop in Iceland"
"Oh rite, you wana know what his groundspeed is now 21"
"Sure"
"850, 875, 900, 925"
"We cant do that."
Fun of course interrupted by PWO and AAWO being killjoys "radio discipline Freddie blah blah blah"

A crab Freddie mate spun me a dit about a scrambling of the "Q" a few years back. VC10 going up the east coast like the clappers to refuel a couple of F3's. Never found out what the GS was, but apparently the mach meter was rumoured to be to the right of 0.90.

254 kts in a Mooney 201 Tennant Ck to Mt Isa is the best I've got.

Speed of Sound in PA28
 
I almost broke the speed of sound in a cherokee (PA28) once!

Well not quite the speed of sound but 171kts is pretty fast for a warrior. We were ahead of a fairly serious storm coming out of New Orleans and had about a 50kt tail wind.

I have photographic evidence if you don't believe me, can't work out how to put it on the thread though

Rattus 4th Apr 2003 06:35

Once got 390 kt out of a Diesel Astra on a single track road in Skye. GPS jamming trials do have their uses.:=

lowflare 6th Apr 2003 08:09

Maintain high speed, they said...
 
Once I had ground speed-252kts...

ON A 3.5NM FINAL!!!

18-Wheeler 6th Apr 2003 11:50

Prettt good, Lowflare!
I haven't managed that but I guess I've come close at times.
I also used to be able to turn base at about 250kts in the Metro 2 I used to fly on bank runs, not break any gear or flap speed limits and still slow down just fine to make the end of the runway.
A mate of mine used to drive a Westwind - It's a long story but he was clocked on radar on a straight-in approach into Cairns in Aus at 420kts GS at 7 miles.
He made the first taxyway!

visibility3miles 6th Apr 2003 12:24

I was flying a Cessna 150 long ago, turning from base to final, when the tower asked me to "keep your speed up" as a Lear jet was number two in the pattern.

I refrained from saying "in your dreams" and pointed it down (it was a long runway, so I knew I wouldn't run out of room.) Fortunately, the Lear figured out that the max speed for a Cessna isn't much, and gave me time to land... :D

witchdoctor 7th Apr 2003 21:07

Hey Turkish,

Got 186kts in a PA-28 over Arizona one winter according to the LORAN gs readout. Going the other way we only managed double figures though!:(

My names Turkish 9th Apr 2003 06:18

I will discredit you
 
Witchdoctor: whenever I chat to people in an FBO or flying school and they tell me they fly a PA28, I can always amaze with my story of 171kts. Its my only claim to fame and I want it back. Sad I know.

Therefore I must try and dismiss your claim unless you can prove to me that you did in fact go supersonic in the PA28. I have a photo what have you got?:D

witchdoctor 9th Apr 2003 18:22

Memories.......aaah!

When I was a lad.......during the war.....etc, etc;)

Jump Complete 9th Apr 2003 18:45

A couple of years ago flying a C152 up the east Florida coast to Jacksonville I was battling a headwind and glad I'd filled the tanks before take off.
A King air at FL090 above me asked for a GS read out.
"---- I show you at 120 kts.. but if it makes you feel any better I've got a cessna 150 below you showing 40kts!"

(Normal flight time was 90 mins. Took 185 mins. It wasn't a headwind, it was a cross wind, and it took almost as long to get back!)

My names Turkish 9th Apr 2003 21:28

No Photo then?
 
W.D: So no picture then? Guiness will never accept your claim to the world record without proof. So I win.

Somewhere someplace is the designer or test pilot of the PA28 laughing his ass off because he (probably) broke the two tonnne barrier....

Whisky 10th Apr 2003 22:22

Hi again,

On request of many of you I have expanded the aircraft database on this site.
I've now included a database for Executive Jets, (smaller) turboprops (like King Air, Twin Otter etc) and even a database for light twins.

So from now on everybody flying some kind of twin can sent in their pictures.

Enjoy!!!
Whisky

p.s. Don't forget your camera on your next flight!

ColdnFoggy 15th Apr 2003 01:55

430 kts INDICATED, upside down at night over the Barents Sea at 15000` The bird was a P-3.
Didn`t have the time to grab my camera as priorities where elsewhere
:eek:

Tim Zukas 15th Apr 2003 04:46

As for official records...
 
I know 633 knots is unimpressive, except that it must have been the average from brake release to touchdown, or something like that:
http://www.fai.org/general_aviation/...p=3&city=perth

Does any non-Concorde city-to-city record beat that?

Forgive my Ignorance....

Why is you HSI aligned to true not Mag?

If its obvious please disregard and do me the very great honour of not making me look like a total ass in front of all other PPruners

WOK 16th Apr 2003 01:22

Not so silly a question:

In common with other INS equipped a/c with electromechanical HSIs, the HSI is selectable to "Rad" or "INS" modes.

In "Rad" it works in the manner you are probably used to, and referenced to the appropriate compass. In "INS" mode it is referenced to True, the CDI is referenced to the desired track as required in the INS, and the beam-bar indicates linear deviation from track. (If you look you should also see a small "lin" flag on the HSI).

Very similar to the 747 and, I am sure, other types which first flew in the 70s.

Hi all,

I've just finished redesigning the website and also changed the adress.
It can now be found at:
