One of the problems with my '22 is that Comm 2 is nearly unusable because the signal is weak, both receiving and transmitting. I am curious to know whether this is a known problem and how many others have this problem. I’ve heard of at least one other '22 with a weak Comm 2.
I’ve asked Cirrus about this, but so far haven’t heard from them. My impression, and it only an impression at this point, is that they are reluctant to comment on problems which are common to a number of their aircraft.
One thing I learned recently is that the low fuel light in the '22 has a five minute delay. This was not the case the '22 I flew at Cirrus, 140CD, but that plane was really partly a '20, especially in the fuel system. My guess is that they added the delay so that the pilot wouldn’t be bothered by the low fuel warning light during turns/climbs/descents that move the fuel around.
I never saw my low fuel light come on, despite being well less than 14 gallons in both sides for some time (more than five minutes). But when the service center drained the tanks, looking for this problem to recurr, the light worked perfectly. So maybe the problem is intermittant.
