That should be standard practice. If there is a carb heat device fitted, it is there for a reason and that is to help avoid carburetor icing. By just dismissing it as not necessary is poor judgement and passing this on to students is poor management. Carburetor icing can occur at ambient temperatures up to 35 degrees under the right conditions. -
When I was a student over 40 years ago there were heaps of touch & goes with full 40 deg down to none & in a 172 the controls are quite heavy compared to many other training aircraft like a 150 or 152 & pretty much all recreational aircraft. The method drummed in to me was always carb heat cold, full power, yoke forward to counteract pitch while the electric flaps retracted & airspeed built up. There is quite a bit of pressure required to keep the nose angle down for speed to build while the flaps retract. Every now & then my instructor would yell something like "sheep on the runway go round" when on short/late final & the method was always the same. Like most students I got it wrong in the early stages sometimes forgetting the carb heat off on short final & retracting flaps before full power. What happened here seems obvious to me but I have no knowledge of the training methods, the instructors assessment of the students readiness, the students attitude, understanding, ability to react to change, etc.

A bit blurry but the rounded wing tips look like a cub though the tail after the fire is Cessna.

I assume he had flaps deployed when landing. If full that would be 40 degrees. If it was a T&G it should have been full power, yoke forward to keep the nose down, raise flaps & as speed builds, bring the yoke back to climb pitch. Simple enough but with other things like turbulence and the fact that this was an inexperienced pilot things get mixed up or forgotten & then the excretia hits the fan

I went for a Gyro flight a year or 2 back. It was a tandem seat open cockpit modern one (Don't know make or model) with a Rotax 912. Not sure of the model but it looked like the ULS one. Flying up the Clarence River and through the gorge plus some very narrow ravines etc was quite exhilarating & felt quite safe as you can put one down virtually anywhere. Not so with takeoff though. What I didn't like was the shuddering and shaking when in many different manoeuvres. It felt like it was going to shake itself to bits. Didn't worry the pilot though.

Better to deal with the problem head on and suffer any consequences than do a Boeing & not tell anyone.

Many EVs use heat pumps. Mine does. Some call them reverse cycle air conditioners. They are greater than 100% efficient. An internal combustion engine is about 30% efficient. Most of the energy from the fuel is converted to heat. Use that heat as best you can & an exhaust shroud is by far the most simple and effective way to do it.
-
An electric resistive heater is very power hungry although 100% efficient. A standard 1 bar household heater consumes 1 kilowatt of electricity at 230 volts or just over 4.4 amps. At 12 volts that would be over 80 amps. You would need 20 amps minimum and that wouldn't be that effective with OAT below zero. A simple exhaust shroud is the most effective IMO. The Jabiru one fits around the straight exhaust pipe and not the muffler which is similar to T88s RV on one exhaust pipe and much reduced risk of CO poisoning.

The video shows what appears to be the wing and a small piece of the fuselage with another piece separated from it & smoke coming from both wing tips. It doesn't look real or anything like a C130 to me. There are other reports showing the burnt out remains & Al Jazeera also shows the large ball of smoke presumably just after the fireball when the aircraft hit the ground. https://www.stuff.co.nz/world-news/360883218/turkish-military-plane-20-board-crashes-georgia

I'll fly her in and Europa on touchdown.

Wouldn't bother a Kiwi Ag pilot. Obviously a one way landing personal strip & the concrete is really only needed for reducing rolling drag for takeoff especially is the grass was wet & soft.

Wing Aviation Pty Ltd drones - coming soon to Melbourne

This is the beginning of the end for aerial crop spraying and top dressing by manned aircraft & the main reasons are cost and accuracy. My neighbour in NZ had an airstrip on his farm where the Crescoes had to takeoff & land on a hill under some 22kVA power lines. I went up with the pilot once and was blown away by his skills. I'd sit on my veranda and watch him dropping load after load of super phosphate. Each trip was only about 3 minutes. It is a shame that we will see the end of this but technology & electrification will see its demise. -
Just like the Mini in 1959. Engine gearbox & diff lubricant was shared.

No it was designed and built by North American Aviation to the original specification provided by the RAF to the British Purchasing Commission. The commission was established in November 1939 to co-ordinate the purchase of war supplies in the USA. https://en.wikipedia.org/wiki/British_Purchasing_Commission

It's been called "The engine that won WW2" which is rubbish of course but it does say a lot about the fact that it was used in many different aircraft and other vehicles and had a legendary service life. The Mustang which was originally built to a British RAF specification performed poorly with its original Allison engine, but once powered by the RR Merlin became legendary itself. It began producing around 1000 HP & was steadily improved during the war outputting 2000 HP by the end of the war.

Hands & feet off your aircraft should fly straight & level. If not it is not trimmed properly. Vertical trim is a central trim wheel attached via bungees to the centre stick and adjusts the whole stabilator. I have no trim tabs at all & that was due to me being very fussy about side thrust and washout & making sure everything was balanced. Mt 3300A engine is offset 4 degrees which looks horrible with the cowl off & is 2 degrees more than recommended by Jabiru but exactly what designer Garry Morgan said when discussing engine positioning during my build. A rudder trim tab is what you need.

The record is for the youngest "Accompanied" person to fly around the world. 67 days most of which would have been waiting for good weather. Flying the magenta line & the odd radio call, different languages, cultures, aviation rules and airports would have some interesting parts but most of it would have been really boring I reckon.

The Aero club at Hamilton in NZ had an earlier Cherokee 6. Crashed and burned in a slmilar manner. Luckily that time they all got out.
-
The guns had been removed probably to save weight after adding the second seat (later versions had canons) & the prop looks to be composite not metal. Looks very repairable to me but won't be cheap.

From a design perspective the A320 is far more modern designed as Fly by Wire from the start. The 737 still has all the cables and controls that can be manually managed. The undercarriage is too short also so the engines have had to be steadily move forwards and upwards with a flat bottom cowl to allow the newer larger and quieter engines to be installed resulting in stability issues that had to be addressed such as MCAS which was largely the causes of the crashes in Indonesia & Ethiopia. This led to the grounding of the 737Max & the fallout for Boeing and its management culture has resulted in Airbus leapfrogging Boeing and the worlds biggest commercial aircraft manufacturer. Boeings reputation kept spiralling downward as many other issues appeared. If it wasn't for the US government military contracts Boeing may have gone bankrupt. Like all big US companies that screw up they get deemed as too big to fail & the government bails them out.

Correct. I use Thunderbird Email client which allows you to to view and download the message source which lists the trail including the email addresses, hosts and servers etc. I provided this to my solicitor who in turn sent details to their website providers. Whether anything could or has been done I don't know. It was the solicitors email that had been infiltrated and that is where they got my email address. They just lifted the logo off the website. The email asked me to deposit money into their fake trust account. About a year ago I got an email demanding money in the form of crypto currency. They had managed to get my email password & got in to my mobile phone account but got stopped there. I changed all my passwords & set up 2 factor identification & had to get a new sim for the phone but other than a lot of effort I lost nothing. About $2.74 billion was lost to scammers in Australia in 2023. Reported scams this year amount to $210 million so far but not all are reported. You can see the stats on the scamwatch web site.

The verification of bank account information is not done by email or web based information. Often you need to ring a trusted phone number, get info via text, check numbers with the bank etc or obtain a hard copy printout. Scammers are becoming increasingly sophisticated. When getting info from my solicitor via email, I got an email from a scammer using their logo. It was obvious to me but wouldn't be to many people.

That is already in place. I sold an investment property and my house and bought another house & everything was done on line with no paper at all using a system called Pexa that solicitors use and Docusign for signing contracts and property transfer documents. Both systems required that I provide IDs and I needed to upload photo scans (PNG or JPG) through another system called Infotrack. Once all the ID stuff is confirmed documents are signed without any witness being required as it had to be before.

I bought a $US6.95 3/8" snap fitting for my air riveter in 2011 from Aircraft Spruce when building my aircraft as the same item from Hawker Pacific here at the time was $60.00. Freight cost was $US59.00. Once bitten twice shy. After that the the only way to get a reasonable freight cost was to buy a number of things at the same time in a shared order with others.

China is sorting out their supply chain
kgwilson replied to danny_galaga's topic in Aircraft General Discussion
The F35 was supposed to be the aircraft of the future that could perform all functions of fighter, bomber, launch pad, stealth, performance etc. It was conceived in the mid 90s and had huge time setbacks & ridiculous cost over runs during development. The first examples cost more than $1 billion each. It has the best technology but in the end is a compromise. Like a jack of all trades it is a master of none.
