@KashFlow Getting this error 'The transaction log for database 'Keybooks' is full due to 'LOG_BACKUP'.' when logging in. Have your customer service agent updated you on the problem ?
Just plug in. That’s it.
Autocharge is now available on the GRIDSERVE network, taking the hassle out of EV charging. Once set up in the app, your vehicle knows what to do: no buttons, no cards, no waiting.

@ibrocksom Hello Ingo, thank you for reaching out. 😊If you experiencing errors in speed limits and cameras, please report them on MapShare Reporter: tomtom.com/mapshare/tools…. It will be reviewed by our Mapping team and updated once confirmed as an error. ^Nikita
@ListerLawrence And of course it wasn't just 3 minutes. You had to drive there, fill up and then walk to pay, queue to pay, walk back and drive back off the forecourt.
@KiwiEV Is it possible to convert the DC to CCS for better charging compatibility or would that just add too much additional cost. I see a few CCS to Chademo adapters are now available.
I’ve owned this 2011 Bentley Supersports for a 3 years. In that time it’s been fully operational without fault for about 2 weeks. Not even joking! Currently the roof has stopped working, the battery lasts about 2 days then loses charge and the suspension has a failure notice. 😩
@rwyrachel Whilst you mentioned the 10 antennae, you neglected to mention the huge banana at the rear of the aircraft and I feel this would be of more help in identifying the aircraft! 🤣 [To point out the bleeding obvious, this is not a serious reply!]
@MCCCANM In 1978 I worked for a division of Decca in the UK that designed and built 'experimental equipment' for customers. One project I worked on was to built a rugged data transfer unit. This was to update flight computers with a rising and falling path - pax didn't enjoy it though.
Do airplanes fly at a constant altitude?
Sort of. Our altimeters say we do, w/ variations of a few feet, more due to turbulence
If you could measure to the ground, though, we’d be all over the place. We’re just going with the (pressure) flow
This is how the altimeter works!
Altimeters provide a readout to pilots of how high they are in the sky. Large airplanes usually have three; one for left & right seats & a “standby” in the middle (often combined w/ an attitude indicator & powered by battery in case of an electrical issue)
They work based on air pressure. The higher you go, the lower the air pressure & temperature. We use a “standard lapse rate” to estimate these; from sea level, the temperature decreases 2°C & 1” of Mercury for every thousand feet you climb (Mercury, Hg, is used as our measurement for pressure, though most other countries use millibars)
The atmosphere is complex & dynamic, though; the standard rate isn’t perfect, but it’s a good general rule. We’re going to revisit that in a minute…
Altimeters use this concept by simply measuring the pressure outside & converting it into an altitude readout. They generally do so mechanically, though most readouts in modern aircraft are digital
“Static Ports” on the side of the aircraft allow us to sample the outside pressure. Don’t confuse them with the “Pitot Tubes”, which stick out & point forward…those measure airspeed!
The static ports are connect via a tube to the sealed altimeter, which contains a sealed, flexible metal chamber. In the illustration below, the chamber is the “Aneroid Wafers”.
As pressure increases (descending from high to low altitude), the chamber contracts from the pressure. As it does, a small spring moves with it, which in turn moves the long 100’ indicating needle on the altimeter. It measures tens & hundreds of feet
A second & third needle spin w/ the first, using gearing to spin at slower rates. Every time the first needle makes a complete revolution, the second only moves by one digit. This is the 1,000’ pointer. The third needle is the 10,000’ pointer (it sounds complicated but was easy when you got used to it…modern digital displays are very straightforward & just tell you the altitude). The whole thing works the same in reverse, when climbing
We have radar altimeters & GPS, too, but that’s how the primary system works. Now, back to the question…do airplanes fly at a constant altitude?
According to the altimeter, yes. There are small variations, but desired altitude is consistently bracketed
In terms of height above the ground, though, no. We’re all over the place! The atmosphere is dynamic & since our primary indication is pressure, we’re just riding at that pressure, up & down. You don’t feel it, but you can see it if you look closely
A related problem is that pressure at airfields vary day to day & hour to hour. If you couldn’t adjust the altimeter, you could land in San Diego at sea level & have it show you at an altitude of 300’. By morning, it might show -300’
Altimeters can be adjusted to correct for this. Airports broadcast the local altimeter setting on a weather frequency, updated at least every hour. San Diego tells you the local altimeter is 30.05” & you set that in as a baseline…now the altimeter is calibrated to read the proper altitude w/ the wheels on the ground
Since pressure varies widely & planes move quickly, we need some kind of standard when cruising. A bunch of airplanes crossing the country w/ wildly different altimeter settings is a recipe for collision.
For this reason, we set a standard of 29.92” when above 18,000’. Everyone’s altimeters read the same & we’re at the same absolute altitudes. My altimeter might say 35k’, but in terms of absolute altitude, I’m really at 34,754’ or something. Doesn’t matter because the other guy is at 35,754’ & we’re still separated
Once you descend back below 18k’, you set the local altimeter setting & everyone flies off that
Now you know the basics!
@TeslaBoomerPapa Lipo battery powered vehicles are doomed. The future is here now with Hydrogen-electric drive. R&D is complete and these vehicles are being produced now. Hydrogen gas converts to electrical current in a cathode/anode/electrolyte fuel cell. No more battery pollution.
It looks like (some of) the Bozos are starting to realize what's happening in the EV world, right?
Tesla's number were doomed catastrophic because they produced ONLY 430,000 this quarters (with 2 factories closed 3 weeks for upgrade!
What I said was: "it's going to be REAL funny when the CATASTROPHIC results of the "others" are coming out!
So: GM has produced 4,100 NEW Evs, i.e. HUNDRED TEN times LESS than Tesla and they are essentially postponing for ever new productions!
Tesla is EARNING billions while the "others" are LOSING billions
Tesla is RAMPING UP the others are "postponing" or "switching to Hybrids!
BUT "the competition is coming, the competition is coming"
