Tail strikes and larger aircraft types
Larger aircraft do not automatically mean that a tail strike is more likely to happen. However, stretched versions within an aircraft type can be at greater risk. Thus, the Avro RJ100 will have a greater risk then the RJ70, with the RJ85 being in the middle for tail strike risk. The A318, due to fact that it is the shortest member of the A320 family will have a low risk of a tail strike. By the same logic. the short version of the jumbo, the B747-100SP will also have a low risk of a tail strike.
I think the Q400 has also had its moments due to it length.
