In Canada, aircraft at uncontrolled airports usually cross the airport at midfield at pattern altitude from the upwind side, turning onto the downwind leg. Although joining straight in downwind is also a possibility.[5] At controlled airports, the tower typically directs aircraft to join the downwind leg, base leg, or straight into the final leg.[6] In the UK, South Africa, and New Zealand a standard overhead join is recommended.[7] In Europe, aircraft usually join the pattern at a 45° angle to the downwind leg, in the beginning of the downwind leg.[citation needed] Fast aircraft, for example military jets, may enter the pattern with a run-and-break (in the US, overhead maneuver or overhead break). The aircraft flies at speed along the final leg, and makes a sharp, high-G turn above midfield to lose speed and arrive on the downwind leg at pattern altitude and in landing configuration.
