    There's probably one main reason why Jabiru are reluctant to endorse Lithium batteries - even LiFePo4 batteries. And that reason is - despite LiFePo4 batteries being advertised and regarded as "benign" and "completely safe", they will still go into thermal runaway at temperatures around 270°C. They do have a lower heat release signature during thermal runaway, than the other lithium batteries. However - this simple fact means that if you install a LiFePo4 battery and are unfortunate enough to crash, and have a fire start in the wreckage, then the LiFePo4 will actively feed that fire, once the battery reaches the above temperature. One could say, "Well, if you're on fire after a crash, you or your aircraft are finished anyway". However, there are many survivors of aircraft crashes which ended in a post-crash fire, and if one can reduce the on-board items which will feed that fire, then that must improve the chances for the survivor/s of the initial crash impact.

    I don't see the B 707 as ugly. On pods under the wing and forward is the best place for a jet engine. They are even designed to separate if the engine gets well out of balance. Having them in the wing is costly heavy and dangerous (Compromises the spar). One failing bigtime would take out the other and the wing as well The B 707 was the first really safe and reliable international jet liner based on a standard single aisle fuselage cross section that went on many models. Form has to follow function with an aircraft.. it's a compromise in many ways without making it look good for a desk model The wingtips could flex 27 feet without structural damage and that's well before Carbon fibre. Their cruising Mach Number is up with the latest. Lots of flap and spoiler action.. High airframe times are common. wthout angst. Nev

    Guys, This is all about the politics of Controlled Airspace Access and a higher MTOW. Did you note that RAAus are not providing information to any airport operator but only those that are members of the Australian Airports Association. CASA has a committee from the "industry" that provide advice to it on new regulations, called the ASAP. RAAus need that committee not to stand in the way of their request for greater privileges. The AAA won't endorse a regulation change that would result in their members not being able to send invoices to aircraft owners. RAAus's change in position is a quid pro quo for not opposing the CTA and a higher MTOW.

    This is the current method of control. No notice will ever be taken of the membership whilst total control of a roughly 10,000 membership organisation is vested in 4 people - just running their private agenda. Short of another General Meeting to regain control disagreement by members will continue to be treated as only NOISE. Electing 2 members each year will never accomplish change (as it was designed to prevent). General feeling of everyone I have spoken to is discust & annoyance but certainly not surprise. Seems to be an acceptance of an inevitable implosion.

    Looks like they will be used more for regional to city transfers from their bases with multiple patients, rather than actual outback pickups...

    They're fast, that's what the RFDS want. Distance is the killer in Outback Australia, a lot of people have died before they could get crucial medical attention. I'd like a ride in one, but not as a patient. If you crash your vehicle in a remote region, and are badly injured, you just might be very appreciative of the PC-24. I believe their biggest supporters are the people whose lives have been saved by them. I've no doubt, the RFDS has the condition and capability of every unsealed runway sorted, down to the nth degree - and they normally work on just landing at the closest suitable strip, and bringing the patient/s in by road, from the scene of the mishap.

    True the FIRST civilian jet airliner ever - commissioned in 1949. A few short years after WW2 and light years ahead of its time. Yes it did suffer from a fatal pressure vessel flaw (squared off windows). The Brits came up a a completely novel test for the pressure vessel (your water bath) found the flaw, corrected it and Comet flew on. Due to the time out of service Uncle Sam (who had tried to stop both the development of the Comet & its engines) had caught up and put the larger and very ugly Boeing 707 in to service. The Comet continued on in civilian service but could not compete against the much larger 707 and eventually found a new life in the military as the Nimrod surveillance aircraft. To my eye it is still the most a beautiful formed aircraft and I am proud to say I can remember flying in one.
