I agree that the instruments you have nominated are not critical for safe flight, especially within the training (familiar) area. The ones you have not nominated are, especially for the student. Attitude, power & height are relativly easy for a human to judge. Not so airspeed (unless in an open cockpit), when in the circuit/on approach to land. It can be done of course but an ASI is a great help😈

FYI - On Fuel Filters For anyone wishing to upgrade from pleated "paper" media filters - I have a small number of Hengst H102 WK & H 103 WK, gauze media, fuel filters.

I wonder - does corrugated pipe have a greater flow resistance than smooth???😈

Very quick speed read - saw nothing that might justify ASIC being imposed on recreational pilots wishing to access small RPT airports. If you are able to point out the sections that relate to ASIC in the above context - please do so. 😈

Interesting - "..........overwhelming for many older students........" I am far from my first flush of youth and although learning is lifelong, not a student. I am flying a glass cockpit for the first time. Can't say the transition was easy and I still have moments of uncertainty but getting there! The biggest problem for me was knowing where to look and then interpret the diffrent format - time, eventually allows the geriatric brain to adapt. I am not sure that this is any diffrent from moving from one aircraft to another with a diffrent panel/switch /control/ layout. "Glass Cockpits should be an endorsement only, not a training platform." Hmm! If the student is more likly to be using a glass cockpits in his/her future, why not start them on what they will be using. Perhaps "steam gauges" will require an endorsement, for pilots wishing to fly vintage aircraft. "Only fixed pitch props as well." I would suggest that "ab initio" students, heading for CPL, start on complex aircraft/systems from the get go. For the most part they will adapt very quickly, the cost and time taken to qualify, less. While I haven't done the following - its seems that glider training/experince, will deliver lessons in energy management and keeping ahead of the aircraft, that will be a lifelong benefit to the CP (they may get to land a multi passenger glider on a disused (Gimli) airstrip or the Hudson River)😈

How many aircraft can you fit in the hanger?😈

The concrete floor is likly to be the single big cost - compacted earth very little. Your $60K is a luxury job, no doubt with power, water, sewage mezzanine living quarters and 2 aircraft with big wing span. I can comfortably fit my Sonex in a space 8 x 8m with plenty of storage room - Kit farm shed, about $8k (delivered) less on special/sale, self erect. 😈

Naaa! your okay - you just needed to contextualise your cloud base no fly comment😈

Simple - the thrust of this Thread seems to be about allocating blame - there are the pilots blamers and the system blamers. I am not so intersted in the facts of the case , more the commentary from Forum members. I am simply pointing out that the pilot had a history of indulging in activities that are inherently more risky than knitting. It is also likly there were some system failures, (instructor/RAA) which may be lessons that serve to modify the system (a good). Coroners often reflect societal /political expectations - not suggesting corruption, just bias. I think it likly that the pilot, once free of close supervision, would likly have done what he did sooner or later - he was a male!😈

Where does this 3000ft cloud base come from? What of training from airfields at almost sea level?😈

Some observations on human nature - in particular the male of our species (all?). I know very little of the incident that forms the basis for this debate however I ask you to consider; We are an inherently risk taking species. Our stories, glorify the macho man. Our courtship behaviour is often typified by displays of dairing. (look at me!) Pilots of all levels are mostly male - do you need to ask why? Motorcycle riders (of all ages) are mostly men - see above comment. While intensive training (CPL?) will often modify, at least temporarily, risk taking behaviour/personalities, it is unlikly to be a permanent fix. If you want to see videos of aviation risk taking & rule breaking - there are probably hundreds out there. This is classic (male) "look at me syndrome". Males are far more likly to die prematurely than females, in large part due to the testosterone in our veins and the tacit expectations of society. All modern societies spend a ridiculous amount of effort on trying to prevent male risk taking, instead of accommodating , redirecting and accepting the inevitable mortalities that ensue. Our supposedly primitive forebear were much better at managing our instincts. I support any investigation that seeks to determine why an incident occured. Not so that an individual will necessarily be exonerated (or crucified) but that his (usually) actions can be seen in a holistic context. From the little I have read (in this Thread) the dead man was on a mission to risk his life in many ways, before his poor judgement finally caught up with him. The part that instructors/organisation's (RAA?) played is likly a minor one - this does not mean that systemic & personal errors were not made, from which lessons may be taken.😈

"a vfr pilot taking off with a 2000 ft cloud base." Not an issue , IF (?) he is able to maintain 500 ft clear of surface.

Wow!😈

I agree it's a far from ideal situaton HOWEVER the biggest worry is the mindset of the VFR pilot. There is much that a VFR pilot can do to ensure a safe arrival - the Russian Roulette statement is pure alarmism, sorry if I offend.

The Bing diaphragm carburettor, is nothing like the carburettors used by Ly/Con - hense my inquiry. BING: The movement of the diaphragm is controlled by manifold pressure (MAP) The diaphragm (working on the needle valve) controls fuel flow MAP is controlled by the throttle/butterfly valve connection (no mechanical connection to the diaphragm) AND the propeller, acting as a governor. My question is about the ability or not of the propeller to determined/control fuel flow in a BING type carburettor. By using wide open throttle (WOT) rather than another setting, I am attempting to remove the variable introduced by the butterfly valve.😈

Ditto - I was supporting your initial statement however went on to expand on the third party blame game😈

Disclaimer - My following comments are NOT about the incident being discussed in this Thread. "That said the attitude of the pilot is always a factor and as I understand it he was advised not to fly in such poor conditions but ignored the advice" We live in a time in which personal responsibility seems to have been sidelined in favour of blaming/suing thirds parties. I feel that there are two reasons for this: The various causation concepts (eg Swiss Cheese) which have rightly moved the focus on the individual (pilot)as the sole perpetrator/cause of the incident, to one that looks at the system that may have failed. The legal industry (ambulance chasers) who seek to make significant income out of bringing the matter to a court of law - popularised by TV programs & muckraker journalists. While I am in favour of concepts like the Swiss Cheese view of incidents, the PIC is and always will be, the one who is responsible for the decision to fly or not. Swiss Cheese should have the effect of proportional responsibility, not absolution (unless deserved). "in raaus you can fly lightweight slippery fast aircraft the will get you into trouble quicker than a lumbering old cessna so maybe our training needs to reflect the performance of these modern airframes. they are not draggy ultralight aircraft any more." This is a fallacy - RAA's covers a very wide range of aircraft types & performance. RAA'S instructors/schools can only deliver generic instruction. When changing to a diffrent type of aircraft it is the pilots responsibility to seek further instruction ON TYPE😈

Not asking for advice on how to operate prop/engine at altitude - asking for opinions on the effect/influence of prop, as governor, on fuel flow in a Rotax/Bing carburettor😈

Southeastern - Mexico?😈

Brains Trust stumped?😈

Scroll down to Aircraft General Discussion open Scroll down to Start Spare Parts List There is a lot of tangential debate , consider it educational. My recommendations are all for Gates hoses, most (fuel/coolant) of which can be obtained through REPCO, with the exception of the oil hose which comes from Hydrolink "For fuel line I use Gates Barricade EFI (also known as MPI) this is overkill for pressure rating but has slightly better temperature & permeability. This is compared with the Barricade Carburation Hose, which also meet the Rotax specifications. Comes in a range of ID's - there will be one to suit your application. Be sure to get the right size, cut carefully (I prefer to cut, so installed length is covering the whole length of the spigot at each end. Use a hose cutter for nice 90 degree clean cuts and blow through with compressed air before installation)." "Seems that there is nothing available (except from Rotax) in straight hose BUT you can purchase the following molded/shaped hose in 16.5 & 17 mm ID which can then be cut to the required lengths. Note: Most installations will require a little over 2m in total, you will have to purchase more than one of the preformed hoses, so be sure to compare the total price with Rotax supply. 02-1579 16.5mm 02- 1249 16.5mm 02-0912 16.5mm x 755 mm long 02-1415 17.00mm x 280mm long (see below) Gates Silicone comes in ID 16mm (5/8) straight & formed. Silicone hose is usually super stretchy, so I assume 16mm will push on to a 17mm spigot/barb. https://www.gatesaustralia.com.au/-/media/files/gates-au/heavy-duty/application-data-sheets/heavyduty-product-range--silicone-coolant-hose.pdf" "Check out Gates 01 -007, 03-0010 & 03-0011, multi fit, 25 mm ID, coolant hoses" "Oil - Gates 8- GTH hose from Hydraulink. Be sure to order correct ID for your application."

I see worrying matters in the above photos (Blue & IBob). The corrugated oil & coolant lines & the alloy coolant pipes require at least two additional joins /pipe, compared with a single "rubber" hose - this introduces unnecessary potential failure points. The use of "plastic" filters within the engine bay is strongly advised against. The use of pleated "paper" filters is also strongly advised against.

No ASIC! As a child, flew with my parents in a Comet (probably lucky to survive). Beautiful looking aircraft. Unexpectedly small interior. Love the pilot(s) flight cap & gloves - no recollection of these when invited up to the flight deck.😈

Hi Bobcharl, I have no comment on the corrugated metal hose supplied with some kits. All the information you need, to purchase non OM hoses, meeting Rotax specifications, can be found in "Started a spare parts list" for 17mm & 25 mm coolant hoses plus fuel & oil hoses. Unfortunatly there is quite a bit of tangential discussion to wade through but it's there. If you are can't find it/unsure - get back to me😈

Are you sure? - This is a Rotax 912 - there is no direct mechanical linkage to the fuel metering system (as in a LyCon). As I understand it, fuel metering is achieved through influencing the manifold pressure, which is a direct result of rpm. The RPM can be manipulated by the; throttle which is connected to the "butterfly valve ",No 3 in above diagram propeller pitch 😈
