We are 135 and use Fujitsu tablets, not sure of which model, put together by
ADR. The older units came with 0.5G RAM, they have been upgraded so now all units have 1G RAM. Our units all came from Bombardier in new aircraft.
I don't know what Class or software level. We are not approved for paperless cockpit.
Here's a synopsis:
Our EFBs are in our Lear 40XRs. There isn't much room in the cockpit, so it can be difficult to get the tablet in a position that is usable. The Lear yoke is always in the way, no matter where we move the seats. Strike 1: not easy to physically use the unit in
our aircraft.
Our Lears have XM radio, so the EFBs are hooked in to WxWorx weather service. This is, by far, the best part about the units for us. The ability to download current weather during a trip is very useful.
Almost none of our pilots ever bother with JeppView on the tablets. The software is non-intuitive and runs slowly on our tablets. We print paper copies of Jepp charts for all intended airports on the current trip before we leave the office so we don't need the JeppView for normal use, and if we need to divert, or change itineraries it is easier to pull out the NOS books than to fire up the EFB and wait and wait and wait for JeppView. Besides, the problem of limited room in the cockpit makes it difficult to use the EFB in any practical way while in the terminal environment.
Contributing to our non-use of JeppView is the fact that our units are not hooked up to a GPS, so we don't have present position shown on the charts. I know that our previous chief pilot spent a fair amount of time with a bluetooth GPS receiver but was unable to get it to work consistently in our aircraft. Probably because of the heated windshield. This is one area that would make our units more useable.
We have performance software loaded on the EFBs (UltaNav), and this gets a fair amount of use by the guys. It's nice to have an easy way to check second segment numbers in mountaneous areas, but some of the guys use it everywhere for calculating V speeds, take-off and landing distances, and such. I tend to only pull it out for the more difficult airports, but then again I don't normally turn the thing on unless it looks like it's going to be a bad weather day. The QRH in the Lear is pretty user friendly so the old fashioned way of getting numbers works just as well for me.
We used to have two EFBs in each cockpit, but have since pulled one out. They get used so little, and the cockpits are so tight, that just having one unit onboard at a time works just fine for us. It's easy to share the unit when looking at the weather.
The way that the USB cable plugged into the unit left the cord sticking out and prone to being knocked against things. We had a spate of USB port failures on the units because of this. Our MX guys found a neat little universal joint style
USB connector that allows us to route the cables tight against the end of the unit, then inside of the carrying case, and out the opposite end so they are much less likely to damage the connectors.
I'm not a big fan of the updating process. Our units do not have a built in CD drive, so we either have to bring the EFB inside and update JeppView wirelessly, or we make an update pack, install it on a USB memory stick, and send those out to the plane. Either way is a hassle. If we do the update pack thing, the desktop computer that we use has to have the same JeppView serial number software as the EFB. This means that we have a different desktop/notebook computer to match up with each aircraft. If I have to do multiple update packs I have to do it at different computers! I suppose the third option is to hook up a portable CD drive to the EFB while it's in the aircraft and use a disk to update, but I might as well just bring the unit inside as go through that hassle.
Our units have a power cord and a USB cord (for the XM radio connection) hard wired into the aircraft. I really wish that we had a location to mount (and use) the units in our airplanes. That, and more user friendly chart software, and we would use our EFBs a lot more. As it is, there are many, many flights where the units never even get turned on.
