Smoke – 2nd test

A bit if blue sky and yes… blxxdy freezing .. but hey lets try second attempt ..

Tried 1.4 instead of 1.5 on the mixture and smoke was a little less ‘full’

Smoke on …… go

Last Sunday we finally had a slight lull in the weather and .. having fuelled up … loaded about 30% of smoke oil into the oil tank.

Having started up and warmed the engine whilst waiting for the fueller to arrive I had a nice warm engine so was ready to taxi out pretty much straightaway.

I made a quick mobile call to Jersey ATC to request circuits and also advise that it would be a second test of the smoke system. There was a short delay whilst the clearance chap checked out with the tower and all ok.

Duly taxied out and lined up on runway 26 at Jersey .. with a nice warm engine … I had said I would probably do a full normal circuit before doing a long runway pass at say 700’ and try the smoke on and off serveral times.

Just after take off .. I banked out left towards Corbiere lighthouse and quick glance in my new small rear view mirror … thought .. let’s just flick the smoke switch for say 2 seconds and off…

RESULT …..

Lots of lovely white billowing smoke and stoped the instant you turned off. A few more on,off combinations and works a treat.

Clearly my previous setting of 2 full open valves on the mixture was way too rich .. Smoking Airplanes had suggested trying something between 1.3 and 1.6 .. I tried 1.5

Awesome smoke trail ..and BEST thing … if you waited for say 2-3 seconds and then looked back .. you could see the biplane wing wash and prop wash swirl beautifully symmetrically in the trailing smoke.

Will try a rear facing go pro on the next flight ….

Slightly fast approach….

Here is a slightly fast approach around August 2019 …

It was slightly choppy conditions but I planned a touch and go and … as you can see … the touch was ok but the starboard wing lifted a little as the approach speed was too fast .. 😊

Smoke – First

The other day was a very cold but at least clear day so I half filled the smoke oil tank with baby oil and ratcheted the securing strap up for its first proper air test.

I’ll need to source a better power plug connector .. these ones with crimped spades that push into plastic connector blocks are very weak … but should be ok for initial test.

Having run an initial 1 second ground test to make sure the pump operated from the rear cockpit switch I set off to get in and warm the engine

Getting in was its usual squeeze in the winter.. with around 5 layers on .. its cosy though and you soon dont feel the cold as everything gets going

I’d pre briefed I think it was Russell in ATC that I’d like to do a circuit just to make sure all fittings were stable and my feet remained clear of all fittings in terms of rudder access and pump … and then advised I’d like to do a straight pass over the runway at around 800′ to try the smoke …the idea being that if anything was to happen .. I could dead stick down ..

All went fine and setup the approach for the first 800′ overly… slight thing to factor was an ATR had just take off as I was on short final so I was advised to turn before I flew through his prop wash at the end of the runway .. not a problem as I usually turn just before the end to clear the centre line

Anyway … my little wing mirror I fitted a few weeks ago revealed zip coming out of the back .. tried the switch several times and nothing…

Did 4 more circuits and finished with a usual very tight 1 min circuit to land … the ATC controller was awesome as I called close downwind she cleared another FlyBe ATR to take off and he was pretty slow to move so I held a few more seconds until I saw him roll then wing over on a nice tight right base and touch down just a few seconds after his wheels left the ground…

Thanked ATC and wished a Happy New Year and taxed in to check why the oil wasnt working …

Checked all fittings and switches and fine …the realised.. doh … to prevent any spillage I’d turned the flow valve fully off … this means loading the tank is a nice dry affair ….

Anyway .. valve duly turned on and a hop back in and clear prop .. restart …and hey presto .. smoke … not as billowy as I’d like.. but smoke

Stopped the engine hopped out and found a very wet undercarriage…so it’s too rich

Turned mixture , flow down from 2 full turns to 1

Hopped on again …and restart… not much smoke.. but less liquid …

So need to check what flow valve setting is optimal and also emailed Smokin Airplanes in US to see what is best burn rate for oil on this type of.engjne … prob better at revs around 2700 vs on hard standing around 1800

Watch this space ….. 😊

Last flight of 2019

It’s been such rubbish weather during the past few months , and the odd day it has been good we have been in the U.K. ..

Top that with a drop dead CAVOK day with 3kts … and it was Christmas Day .. and Jersey airport was shut ….

Mind you .. we all need to count our blessings … the airport DID open … briefly …. to let a medivac aircraft fly in from Guernsey .. an Aurigny aircraft, to pick up a sick person then fly them to the U.K. .. usually Southampton .. fingers crossed all worked out ok …

A few shots from the last days flying of 2019 … pretty cold .. so usual 4 layers top and bottom … plus a life vest on top of a flying suit and sheepskin … that was tight in the cockpit !

Video learnings …

It’s really useful to study some of the earlier go pro footage from earlier in the year ..

Using stills from this you can see how accurate, or otherwise, you are in holding angles or turns …

The sun on the wings shows a straight line … but not quite 90’ with the horizon …

Local Photographer pictures

A local guy (Alan Carvo) in Jersey has a real eye for a different angled shot and very kindly sent me some images that he took at the static display at this years Jersey International Air Display … I’m hoping to arrange some nice clear landing shots with him in exchange for a flight and some fun flying around 🙂
