mkennard Posted February 18 Posted February 18 My aircraft POH Maximum Ambient Operating Temperature 38°C (100°F) Jabiru. 1

onetrack Posted February 18 Posted February 18 Don't all Melburnians go inside, and shelter under airconditioning, when the temperature reaches 37°C? 😄 1

djpacro Posted February 18 Posted February 18 Some traffic showing on Webtraks. I’m away at the moment but my guess is the wind per BOM observations stopped many. The temperature is not pleasant so some may have cancelled for that reason. Most of the airplanes there were certified to CAR 3 or FAR 23. No specific temperature limit in the POH/AFM even though performance charts may stop at 40 deg C. 2 1

mkennard Posted February 18 Posted February 18 I doubt the Jabiru would've crashed because it was 38C but the engine temps might've been high. 1
facthunter Posted February 18 Posted February 18 Easily fixed by raising the climb speed slightly BEFORE the engine temps get too high.. Nev 1

facthunter Posted February 18 Posted February 18 Not referring to this specific Incident. Just a general comment and density altitude must be allowed for Always. Best climb performance once airborne will be with flaps up. (Rate of climb). Nev 1 1

If that was normal, it can get quiet based on the law of averages; Just as I've thought the radio was out a few times three people in a row will talk. 1 1

Good idea though, I have the atis numbers on my phone. Maybe it was just a quiet day. They might have all been in the classroom with aircon as it suggested. When the they stop flying the silence is deafening. You get used to the sound being there all day and a lot of the night. Edited February 18 by BrendAn
facthunter Posted February 18 Posted February 18 Moor or lessabin. I goi inside when it's above 30 C. Mad dogs and Englishmen go out in the Mid day Sun. I hate Heat.. Ideal temp is 24. Nice day today. The Ulysses Boys were lined up ready to go at 10 00 as I went to the Men's Shed. Nev 2

An LSA 55 fully loaded would not climb well In that heat surely. I thought the j170/230 wing was developed to improve climb in Queensland heat. Cliff banks trialled the first one at swan hill.
mkennard Posted February 18 Posted February 18 I don't think that temperature is related to Density Altitude for this limitation. 2
facthunter Posted February 18 Posted February 18 I've flown a 230 at Ballarat as the owner was anxious to complete the training at 42 degrees ambient. It performed well enough but for the Occupants it is just Awful. You can't function in those conditions. It went back in the Hangar. fairly quickly decided by Me. . I recall some other small Plane was flying too. There was no issue with the engine temps if you climb at a faster speed. Ballarat is well above sea level Enough to affect performance significantly, Nev 1 1

facthunter Posted February 19 Posted February 19 You have to decide whether it will perform or it won't There's ways of determining that. Like what altitude will it easily achieve in those conditions. Some Planes wouldn't make 3,000 feet so I would not even try, The Lsa 55 Jab is a bit of a rocket with the small Motor also but just Off the cuff, I would think the 230 is Better. How readily it gets airborne is another confirmation of capability. The 4 seat Version struggles in hot conditions, understandably. Nev 1
