I need a reference to cover the following situation:
Enroute to destination airport, an aircraft loses communications. On arrival, pilot adheres to loss of comm procedures and conducts an instrument approach to minimums - but has to go-around due weather and divert to alternate.
From this point I cannot find concrete guidance in the regs as to what altitude he is supposed to climb to when diverting to alternate. My interpretation of the regulations is that he is required to maintain the MSA for the route. This would present serious problems with respect to fuel burn at less than optimum altitude and seems ridiculous.
So, anyone able to point me to the appropriate documentation??
Thanks
