Lack of pictures also strikes me as a danger sign.
It’s a bit sad for sure in general, but this one is the first advertisement I’ve seen from behind the barbed wire fence! Hilarious!

Hangar options are much better. Plus, If you want to open those supercharged engines up and do 200 kts, the long wing is just getting your way until above 11,000’
My emoji’s don’t work, but insert a couple of ear to ear grins.

Environmental and Pressurization / Re: Enviro Mass Flow
« Last post by schrambow on July 10, 2024, 01:17:49 pm »Hi guys,
in my 980 (enviro) for the last 6 plus months, i have been using mass flow all the time above 7K or so. It would give me max differential all the way up to 28K perfectly. I know i have a few cabin leaks and used it continuously for the past 6months, and now the bird is in the shop for a 150hour and to fix these cabin leaks. Hopefully, they find and fix all the leaks so i don't have to use the Mass Flow, but it is a nice feature to be able to take some of the bleed air if needed due to a leaky cabin, until one can get it into a shop to fix. If fixed, maybe i can see more bleed air to the power plant and more speed, lol? It would also be great to see alot more -5 or -10 ISA too!

« Last post by Bruce Byerly on July 08, 2024, 12:39:22 pm »The gauge sending unit looks like something out of a 1949 Packard. I wouldn’t trust it but it does have value and works fine when it works fine. Sticking the tank probably works above 100 gallons - I need to make a new stick but I also have extended range tanks that are interconnected so won’t be useful data to share especially considering some hold 10+ gallons less than 156.
The problem with the gauge system is that it can fail mid range and that has caused some bad outcomes. Lots more to the stories but need to be careful. With all the info that a flow meter can provide and careful tracking, I can usually predict down to a gallon or two what I have burned and verify that with a true top off when convenient. I do the same with turbines so I have confidence in the system.

« Last post by donv on July 08, 2024, 12:35:08 pm »This was interesting, from Facebook:
There’s an issue with the cannon plug for the fuel quantity sender. Gary Gadberry explained it when I bought my 500B. In the plug are two pins. If one pin becomes disconnected, the fuel quantity indication will stop at approximately 80 gals. If both pins fail to make contact, it will then stop at 30 gals. I may have some of it wrong, but I always watch for this. It would behove everyone to make sure this has been safety-wired after maintenance on this system.
