Why can't all Jeppesen Terminal Charts be sent to the Map on my device?

Jeppesen Terminal Charts (Approach plates), including VFR AERODROME CHARTS and VFR APPROACH CHARTS that have higher levels of detail (such as colors, or covering a larger than usual area), cannot be sent to the Maps on older iPads and iPhones with less than 2GB of RAM.

All newer iPads and iPhones have at least 2GB of RAM. Currently supported devices with less than 2GB of RAM include:


  - iPad Air 



  - iPhone 6/6+
