I agree 100% with good lookout, but disagree with;
“Saints preserve us from those who rely on the radio to do their lookout for them ”
If you can get a RIS then it is a huge boost, particularly in poor VMC and it is your only protection in IMC. Getting a RIS when flying into the sun on a typical British summers evening with lots of haze is a really good idea, but you do not have to stop looking out as well.
And you've got the situation of a newly qualified, low hours pilot who asks for a RIS.
NOT so as to avoid lookout, but to provide another pair of eyes which may spot someone you've missed 'cos your workload is high and you're inexperienced....
