CHAPTER SEVEN CHG 4
Pattern Interval. Determine the number of aircraft and visually acquire each aircraft to
determine the proper interval. You have "interval" when any of the following conditions
The aircraft ahead of you is abeam or behind your wingtip AND has completed at
least 90º of turn.
The aircraft ahead has departed in accordance with course rules or simulated Low
Altitude Power Loss from the Pattern (LAPL(P)).
At a tower-controlled field, the above conditions are met, AND you are cleared by the
At Navy Corpus: If the preceding aircraft is a full stop, the proper interval is 45º
behind your wingtip.
For AOA approaches (either you or the preceding aircraft), your
instructor will judge the proper interval for the crosswind turn.
Upwind. The extended runway centerline past the departure end.
Downwind. That portion of the racetrack pattern offset from the runway in the opposite
direction of landing.
Crosswind Turn. The turn between upwind and downwind.
Abeam. The position in the racetrack pattern abeam the intended point of landing at
180º Position. The position in the racetrack pattern opposite the intended rollout point.
11. 90º Position. The bisector between the 180 and intended rollout point. The aircraft should
be 450 feet AGL and perpendicular to the runway. Airspeed is dependent on the type of
approach. (Civil equivalent: BASE LEG)
12. Final. The extended centerline of the runway with 1200-1500 feet of straightaway at an
altitude between 100 and 150 feet AGL. Airspeed is dependent on the type of approach.
13. Intended Point of Landing. This is the point on the runway where you intend to touch
down. Many outlying fields have a box painted on the runway to assist in referencing the
position for landing. Touchdowns should be made on centerline at the intended point of landing
to 500 feet past that point. If a crash truck, wheels watch, runway duty officer, etc. is positioned
at the approach end of the duty runway, do not touch down prior to them. TW-4 exception:
Refer to local Course Rules for operations at Aransas County Airport. TW-5 exception: Touch
down prior to the RDO cart at NAS Whiting Field is allowed.
