FAA Sport Pilot Airplane (SPA)Airspace and NavigationHard
A pilot is approaching a non-towered airport with no other traffic in the pattern and no wind indicators showing a preference. According to standard traffic pattern procedures, how should the pilot enter the pattern?
- AEnter directly on a base leg at pattern altitude
- BEnter on a straight-in final approach regardless of other considerations
- CEnter on the upwind leg at 500 feet below pattern altitude
- DEnter on a 45° angle to the downwind leg at pattern altitude
Show answer & explanationAnswer & explanation
Correct answer: D. Enter on a 45° angle to the downwind leg at pattern altitude
Standard traffic pattern procedure recommends entering the pattern on a 45° angle to the downwind leg at pattern altitude. This provides the best opportunity to see and be seen by other traffic and is the FAA-recommended method for non-towered airport entry described in the AIM.
Why the other options are wrong
- A. Entering on base skips the standard entry point and increases collision risk from unseen downwind traffic.
- B. Straight-in approaches are discouraged at non-towered fields due to reduced traffic visibility for other pilots.
- C. Entering below pattern altitude on upwind is nonstandard and dangerous around departing traffic.
Standard Traffic Pattern Entry
The recommended way to enter a traffic pattern at a non-towered airport is on a 45° angle to the downwind leg, at pattern altitude, to maximize visibility of other traffic.
- Pattern legs: upwind, crosswind, downwind, base, final
- Standard entry: 45° to downwind at pattern altitude
- Left-hand traffic is standard unless otherwise indicated
