OLF PATTERN AND OPERATIONS
The following procedures guide you from OLF entry to in-pattern operations to OLF departure.
With no tower control, OLFs provide our most basic landing pattern training environment. A
Runway Duty Officer (RDO) and a crash crew are normally positioned at the approach end of the
runway. They safety observe pattern operations and provide traffic de-confliction/general
information for aircrews.
The procedures below are designed to provide a safe, manageable OLF pattern, supporting up to
six aircraft at one time. The basic geometric ground track and in-pattern operations are the same
for naval air stations, such as Sherman Field. Study well the following procedures and, although
a few of the radio calls are provided, review the Voice Communications Study Guide for
expanded radio procedures in the pattern.
OLF Break Entry:
1.
Determine the duty runway. Select the appropriate frequency and transmit, "Field name,
landing." The RDO/crash crew will reply with the duty runway.
2.
Diligently clearing for traffic, fly to establish the aircraft at the appropriate two mile initial
for the duty runway. Make the initial radio call and proceed inbound.
NOTE
At Initial, the aircraft should be on extended runway centerline and
heading (reference the EHSI) at break altitude and 200 KIAS.
3.
Approaching the airfield, offset the runway up to 1/4 WTD on the opposite side of the
break direction (i.e. offset to the left for a right break). As you offset, attempt to determine wind
direction (windsock, etc.). Begin intently clearing for pattern traffic on the downwind and/or
crosswind legs. Locate your "interval" traffic (the aircraft you will be following).
NOTE
You are "#1 upwind, with interval" for the break or crosswind turn
when: 1) the aircraft ahead of you is abeam or behind your
wingtip and has completed at least 90 of turn, or 2) the aircraft
ahead of you on the upwind leg has departed the pattern (thus
negating any "abeam" requirement to turn).
4.
When at (or past, if delaying turn for traffic) the upwind numbers and "#1 upwind, with
interval," transmit the break radio call.
5.
Simultaneously, roll into a 45 AOB level turn, reduce power to 10%, and extend the speed
brake. Trim for deceleration.
