Re “Rubbish radar (As a result, frequent lightning strikes and turbulence encounters)” from Ghengis Cant, suggests that he should seek advice from the manufacturer on Lightning strikes, but as he appears not to be an operator that might be difficult.
Embraer had concerns that the 135/145 aircraft, which appeared to suffer more than the average (expected) number of lightning strikes and commenced a research / customer information plan in 2001.
The problem involves the A1/A2 B1/B2 ratios: - for the less technical minded in ‘Tech Log’ - the frequency and location of lightning strikes are proportional to the ratio of fuselage length and wingspan, the fuselage diameter and the window size; thus a long / thin aircraft might suffer more strikes than a ‘fat’ aircraft; as an example for Ghengis Cant the 757-300 could have more strikes than a 757-200.
The strike location is just as important as the total number i.e. composite structure and possible electronics damage.
Best practice in minimising lightning strikes by avoiding cbs does not require an exceptional weather radar, only a good crew.
