As an active IFR pilot, I have been trying to go paperless for quite a while. Finally with the advent of the iPad, this may be possible. After researching all the current products, I came to the conclusion the ForeFlight HD was the most mature and reliable way to go. So far, I am very happy with the approach chart presentation, but less impressed with the IFR enroute charts. These are OK until one enters a congested terminal area, where these charts are so cluttered they are unusable. Unlike the approach plates, the zoom feature of the iPad does not work with enroute charts from ForeFlight. Anyone interested in seeing what I mean can select the KPOC airport, then switch to the low altitude enroute chart and examine the airway structure just south of there. Does anyone think they could navigate through this area under IMC conditions with a little turbulence. Forget it! I have talked with ForeFlight and they don't seem to have a solution right now. The thing I most like about ForeFlight is the ease of keeping everything up to date. It can't be any easier. The product is also a bargain at only $75 per year. With a couple of improvements, I would gladly pay twice this amount. The same data from Jeppesen would cost ten times as much. Anyway, aside from the readability of enroute charts, I think ForeFlight is the pick of the litter.
