timshel - good idea this insurance info - I have a tecnam insured for 128 k and premium is $ 4300 - insurer seems to be 'Vero' - this is about my 3rd year and has reduced some - I have 600 hours and a $ 1,500 excess
the ratio of the 2 premiums are about the same - so I think (I guess) you have a good deal for the hours you say you have flown
no doubt all us 'insured' hope our 'insurers' will reduce their premium each year - if we have been good - I suspect for one reason and another and after a while it does not reduce much past a base level ?

FUEL COCKS
in Tecnam
summary ?
I know that if you keep the black tooth in the middle of the happy face (slip indicator ?) then flight is balanced ......
Even if I lie - the question remains the same - what happens towards the end of fuel supply ? To say you would n't use your 45 minute fuel reserve (or whatever reserve you are comfortable with) is something you can't say. Circumstances may make you want, or have to, keep flying and consume what fuel (or reserve) you have.
True, a record of actual flight time helps
I am not talking about airmanship or fuel stains on flaps
I'll try and find the technical answer and post it (the answer might be that fuel exhastion of both tanks occurs at the same time - towards the end of their volume they evenly empty at the same time )

FUEL COCKS
in Tecnam
Irrespective of what the operation manual says ?? - with the 2 fuel cocks in a high wing Tecnam, what happens when the fuel contents get real low ?
If you fly for say 2 1/2 hours, fuel consumption will be virtually from one tank - 1/4 full - whereas the other tank can still be say 3/4 full.
The fuel gauges also seem to read more fuel used than what is actually used - safety no doubt
So what say you had 2 1/8 full tanks (say you had to ...... or wanted to keep flying) - I'd bet the fuel gauges would be reading 'all but zero' - but with 25 litres you could fly for another 1.50 hours
Will all the fuel be consumed from both tanks before she 'splutters' - with both fuel cocks on ?
Has anyone had some 'real time' experience managing fuel with 'all but zero' fuel gauges ?

ozzie chasing plane in aircraft factory - very funny
Me 20 years bacl - kiwi - was in NZ and I did a quick flight before a flight exam test - Cessna 152 (or thereabouts). Flew for about 20 minutes and when landed noticed huge amounts of oil down, along and under the fueslage
Up till that point I had not even thought the that oil filler cap would have been loose or not in correct position
Into the hanger it was to hide from the visitng testing officer of the 'air' - all cleaned up and then pushed out ready for flight exam test - not a word was said to anyone - which in hindsight was pretty bad (there must have been some oil still on the stick so the decision was ........ get it ready !)
Past the flight test as well - I imagine the preflight was better the 2nd time round !

Cost ?
Guessing ........................
1.3 Sportastars
2.2 Jabirus
3.7 new Commodores
16.5 x 2001 Ford AU's
............... Plus wing struts
-
?
Looks like a Tecnam Bravo - P2004 - with remodelled windows and a main wing strut
I guess the smaller Cessnas have wing struts so Tecnam might as well have 'em too
I wonder what the diffrences and design philosphy are between the Bravo and this new model ?

Bums on seats
True - seats and bums should be equal - as always there are variations
Look at overloaded untes in the outback - rolling over.
Go to Vanuatu and see where people hang off utes
I can remember my Dad saying - in a De Hav Beaver - he flew it - him (the pilot) - the loader driver - a young me in the back behind the hopper - and 3 of my friends - I think thats 6 - theirs only 2 seats in a Beaver - plus the last load of superphophate for the day - completed the last spread and then went home
Its all a learning experience to stay on the right side of the regulation

That would be an interesting survey and good info, and, for the benefit of all - even the insurance companies might think this, I suspect - might be good for competition - after all, all aircraft owners have this information .........
Tabulation of:
Hours P in C - total hours - aircraft type - sum insured - insurance co - premium per year, etc, etc
Wouldn't know how to set the survey up though .......
???

Tony - gympie aircraft maintenance - ph - 07 5483 5170 - queensland ! - has the technology
Gympie to far ? - Tony will probably know of closer

Thanks aviators
I think the early concensus is - costs some money - not much extra top end speed (if any ?) - better take off and climb - smoother ride - more drag when you want it - lower cruise revs so less gas
I do 2 x 300 nm trips in a Bravo (Roatx 912) every month - for the past 20 months - and have found that 5200 rpm seems the best setting. The 300 mile trip from go to wo is usually 3 hours - so I'm happy about how I get there and always enjoy whats happeing outside the window
I'll sit back and watch the subject 'props' develop - and maybe make a change when the ball stops rolling - if it ever does
The best thing about these forums is that the 'user' can comment - and can be heard by lot's of others (users and potential users)

hey HPD
I'm thinking high wing Tecnam Bravo - say 100 to 115 knots
This thread could even apply to a Jabiru - about the same cruise and power
I'd like to hear from someone who's got one of those variable 'wood comp' (or similar) props - what does it do for climb or cruise ??
Are they much chop (no pun intended)

This is the thread I want
Some say a vaiable pitch on a Rotax 912 is ineffective (take off or top speed)
If you go fo a long fly - you just can't help thinking that if the blades were tweaked - something good might come of it ?
Anyone out there that wants to share their experiences
What efficencies can be gained - if any ??
-
I am not well versed at mechanics but i see a wealth of experience out there so here goes ......
the 912 i have up front - tecnam bravo - has now been adjusted to idle at about 2000 rpm - on the ground - departure is not a problem - arrival takes a bit more thought. before adjustment (i'd be guessing if i said old idle was about 1400 rpm) arrival was only a matter of closing the throttle and with use of flap - down she'd come - i'd have to admit there were some interesting noises from up front at 1400 rpm (reduction gear ?)
lets not degenerate this conversation into lift and drag - i'm interested in engine life
the theory behind 2000 rpm idle is no more interesting noises up front - which i think's good
so the question is - if you have a 912 with reduction gear (i guess they all do ?) what does it idle at and what about interesting noises up front ?
-
strobe lights gone ? - been there done that
Box of tricks generally behind rear vertical vinyl bulkhead behind seats
New box of tricks can cost about $ 650
Or alternatively - in this instance - tricks within box - theres probably a few - found dead capacitor - cost $ 40 plus labour
FUEL TANK DRAINS

FUEL TANK DRAINS
I need more tecnam chatter
If you read the AD / AN forum it says fit fuel drains to wing tanks - per revison 1 and 2a - where do you find these bits of paper ?
What is entailed, how much bother and time involved ?
thanks for any advice
JM
