How sacred are the sacred six?

[david joyce <davidjoyce@beeb.net>]

A big Amen to James Nelson's decision to make the sacred six into five. The DI
is an expensive , time consuming, power consuming, heavy instrument which IMHO
has become totally useless with the introduction of the GPS. It puzzles me how
many new Europas still appear with a DI mounted alongside a very expensive 
GPS,which
probably has a built in HSI facility, offering everything a DI does and
loads more as well.  David Joyce
