    to fix those mistakes than a computer s mistakes I am not arguing that technology is bad all I am saying is that we shouldn t completely rely on technology as much as we do now Reply Submitted by Martin on November 18 2015 1 59 pm You say this as you are on technology saying that relying on machines is dangerous Technology is not going to fade away no matter how much a nation believes that it is dangerous The best you can do is trust the technology Then you might not become those people who get creeped out by every single bit of new harmless technology Reply Submitted by Rich Linder on November 1 2014 12 28 pm I believe the Electronic Chart Bag ECB is actually better easier to use and lower in cost than paper charts But it must include a backup for IMC operations I use an IPad app called Foreflight and all critical for flight information is backed up in my IPhone as part of the Foreflight concept Two IPads would be even better and even that you ll pay for itself if you fly frequently Paper charts are unwieldy in a small cockpit and they get expensive if you re flying takes you all over the country or planet For about 150 bucks a year you get ALL the charts for both IFR and VFR flight including departure and approach plates for the entire USA and they are automatically kept current each month It don t get better than that One of the very few good deals left in aviation these days Reply Submitted by Marlyn Velez on October 19 2014 10 52 am I think that the technology and science is so advance that anything can happened The paper maps are important too in case of emergency for back up Reply Submitted by Payten on October 2 2014 3 16 pm no Reply Submitted by Gabriel on October 2 2014 2 38 pm No I don t feel safe because what if the computer goes down You won t know where to go Reply Submitted by Jacob crowder on October 2 2014 2 32 pm I believe that all the jobs are cool and all involve navigation Reply Submitted by Scott plain on August 31 2014 9 24 pm Electronics are becoming more effective efficient and durable than hard copies Paper can be misprinted lost torn and ruined Pilots best be using their experience and maps for backup I trust the pilot not the navigation aids Thus keep what the Pilot prefers Reply Submitted by Celestial Navigator Joe on June 29 2014 10 27 am Depending on one system alone is to invite disastor Why wouldn t there be a back up system available I am not suggesting using a bubble sextant but there are other methods available Cruise ships relying on GPS alone have run aground and hit rocks due to malfunction of GPS antenna problems Reply Submitted by Heidi on
