History
Aérospatiale introduced the B1 variant in the mid-1980s to meet operator demands for better altitude and temperature performance; the Arriel 1D1 engine delivers approximately 20% more power than the original B's engine.
Variants
Slots between the B and B2 in the Écureuil family; the B2 further increased power with the Arriel 2B engine.
