1Purpose
This plan assigns geographic practice areas around KOGB (Orangeburg Municipal) so SEAS dual and solo flights do not conflict with each other, with the city of Orangeburg, with nearby airports, or with military special-use airspace northeast toward Shaw AFB. It follows FAASTeam guidance on reducing midair collisions in VFR practice areas: named areas, entry/exit corridors, altitude blocks, and mandatory position reports.
2Design logic
The airport sits 2 nm south of Orangeburg. Clean training air lies in the rural south–southwest–southeast arc. The north and northwest are closed to SEAS practice because of city noise, KXNO North AF Auxiliary (14 nm NW), and feeder flows toward McEntire JNGB and Columbia Class C. The northeast is constrained by Shaw AFB, R-6002 Poinsett, and the Gamecock MOA complex.
| Keep SEAS here | Keep SEAS out |
|---|---|
| Areas Sierra, Southwest, Southeast | Over Orangeburg city |
| Pattern south/southwest arrivals | Within 5 nm of 99N Bamberg when in Area SW |
| Area Echo only after MOA check | KXNO / north toward KMMT–KCAE |
3Frequencies
| Facility | Frequency | Use |
|---|---|---|
| KOGB CTAF / UNICOM | 122.70 | Pattern, taxi, within 10 nm |
| Practice area air-to-air | 122.75 | Position, altitude block, intentions in areas |
| Columbia Approach / Departure | 124.15 | Flight following, IFR; GCO 125.675 |
| KOGB ASOS | 118.525 | Weather |
4Pattern — KOGB
Max concurrent SEAS aircraft in the pattern: 4. Traffic pattern altitude approximately 1,200 MSL (confirm Chart Supplement / local SOP). Left traffic runway 17/35; note runway 05 uses right traffic. Remain clear of the city on downwind/base when using northerly patterns — prefer south gates for arrival.
If the pattern is full, hold in the assigned practice area or delay takeoff. Do not orbit the field or extend endlessly on downwind.
5Practice areas
5.1 Area Sierra (South) — PRIMARY
| Bearing / distance | 170°–200° true · 5–12 nm from KOGB |
|---|---|
| Altitude block | 2,500–3,500 MSL · use odd altitudes (e.g. 2,550 / 3,050) |
| Max aircraft | 2 |
| Use | Steep turns, slow flight, stalls, ground reference, basic commercial airwork |
| Landmarks | Rural farmland toward Rowesville / Branchville — clear of town |
5.2 Area Southwest — PRIMARY
| Bearing / distance | 210°–245° · 5–12 nm |
|---|---|
| Altitude block | 2,500–3,500 MSL |
| Max aircraft | 2 |
| Use | Overflow maneuvers, emergency landing practice, commercial airwork |
| Constraint | Remain ≥5 nm from 99N Bamberg County Airport (15.5 nm SW of KOGB) |
5.3 Area Southeast — PRIMARY
| Bearing / distance | 110°–150° · 5–14 nm |
|---|---|
| Altitude block | 2,500–4,500 MSL |
| Max aircraft | 2 |
| Use | Ground reference, dual cross-country legs, stage-check airwork |
| Constraint | End the area before the 6J2 St. George pattern (St. George is ~23.6 nm SE) |
5.4 Area Echo (East) — SECONDARY
| Bearing / distance | 070°–100° · 8–18 nm |
|---|---|
| Altitude block | 3,000–5,500 MSL |
| Max aircraft | 2 |
| Use | IFR practice with Columbia Approach, longer XC, instrument airwork |
| Constraint | Check Gamecock MOA / SUA status before entry. Not for first-solo VFR maneuvers. |
5.5 No-Go — North / Northwest
No SEAS practice between roughly 300°–030° from KOGB: Orangeburg city, KXNO, and flows toward McEntire / Columbia Class C.
6Corridors
- South gate: Depart active runway → climb runway heading to 2,000 MSL → after 3 nm turn south into Sierra.
- Southwest gate: Climb to 2,000 → turn SW · announce SEAS SW in/out on 122.75.
- Southeast gate: Climb to 2,000 → turn SE · remain clear of pattern conflict.
- Return (all): Enter the pattern from the south or southwest at TPA. CTAF calls at 10 nm and 5 nm. Never arrive from over the city as a standard SEAS procedure.
7Radio procedures
On 122.75 when entering or leaving a practice area, and every few minutes while maneuvering:
“SEAS [call sign], Area Sierra, 3,050, steep turns, remaining.”
State: aircraft ID · area name · altitude block · maneuver / intentions · remaining or exiting. Within 10 nm of KOGB, monitor and call on 122.70.
8Capacity & expansion
| Phase | School aircraft | Pattern cap | Area slots | Notes |
|---|---|---|---|---|
| Open (first class) | 4 singles | 3 | 4 | One aircraft per primary area + pattern |
| Grow | 7 singles | 4 | 6 | Two aircraft in S / SW / SE (altitude split) |
| Two classes | 12–14 | 4 | 8 | Open Echo; OSS assigns areas on the daily sked |
Expansion does not move boundaries. Split each primary area into low (2,500–3,000) and high (3,000–3,500) blocks and schedule by OSS so two flights never share one landmark at one altitude.
9Solo restrictions
- First solos: Area Sierra or pattern only, dual-briefed emergency fields, IP on CTAF monitor.
- Area Echo: dual or instrument students with Columbia Approach — not early solos.
- No SEAS solo in No-Go north/northwest.
10Coordination
Share this map with other KOGB operators and independent CFIs. OSS posts daily area assignments on the flight-room board. Review midairs, near-midairs, and noise complaints monthly under the SMS. Contact airport manager (803-928-1545) before changing published corridors that affect noise or transient traffic.
