The D-5 may be covered by Federal Aviation Agency regulations which
prohibit use of certain "portable electronic devices" on airliners, 
since these may possibly interfere with radio navigation instruments.  I 
would check with the airline before using it.  Assuming the unit is properly 
designed I doubt whether there would be a problem, but perhaps it's not.  
The prohibition does include AM and FM radios, since the local oscillator in 
these might interfere with ADF and VHF navaid recption.
