2. Traffic pattern for main runway, rectangular 3000’ MSL and
overhead 3500’ MSL. When DZ/LZ W of main runway is in use E
overhead patterns may be directed. Expect 3-4 hours refuel delay
during alerts and high density traffic periods. Fleet service is
available on 24 hour prior notice. Payment is initiated with an AF
Form 15 or suitable substitute from the respective branch of
service. No drag chutes available. Inbound aircraft with
hazardous cargo call Command Post 20 minutes prior to landing.
No transient alert services available 0500-1300Z++ daily.
3. Transient aircraft desiring use of Marrion Drop
Zone/Landing Zone/Extraction Zone for training will request
briefing on local procedures through Tactics. Assault operations
on assault strip 2900’ W of main runway. Fly rectangular pattern
at 2500’ MSL. Single and multiple aircraft paradropping heavy
equipment from altitudes up to 3000’ MSL. Final approach to the
drop zone parallels within 2000’ the final approach to main Rwy
34. Use of assault strip requires 48 hour prior coordination with
TACTICS, DSN 461-2794.

4. WEATHER OBSERVING VISIBILITY LIMITATION -
a. Primary Observation Point Visibility Restrictions: East
through southeast visibility is restricted due to permanent
structures.
b. Secondary Observation Point Visibility Restrictions: South
through West visibility is restricted due to permanent structures.
(AFFSA/AFFSA FIL 06-294)
5. CAUTION -
a. Bird Watch Condition (BWC) - Bird activity on the airfield
is relatively low. Few migratory birds frequent the area during the
year and most bird populations consist of those indigenous species
adapted to desert life. Aircrews can monitor ATIS or contact Base
Operations to obtain the current Bird Watch Condition. No
comments on ATIS when the condition is LOW. Bird Watch
Condition Codes are as follows:
(1) LOW - Normal bird activity, fewer than 5 large birds
or fewer than 15 small birds, on or above the airfield with a low
probability of hazard.
(2) MODERATE - Increased bird population, 5-15 large
birds or 15-30 small birds. Concentrations of birds observable
that represent a possible hazard to safe flying operations. This
condition requires increased vigilance by all agencies and
extreme caution by all aircrews.
(3) SEVERE - High bird population, more than 15 large
birds or 30 small birds. Concentrations of birds on or immediately
above the active runway, taxiways, in-field areas and other
specific areas that represent an immediate hazard to safe flying
operations.
(AFFSA/AFFSA FIL 05-122)
b. Report all bird and animal strikes on or in vicinity of Dyess
AFB (KDYS) to Base Operations, 7 OSS/OSAA DSN 461-2515 or
Pilot to Dispatcher 139.3/372.2 in accordance with AFPAM 91-212.
(AFFSA/AFFSA FIL 02-19)
c. BASH PHASE I - All months not designated as Phase II.
Wildlife activity is generally LOW during these periods with the
primary threat resulting from occasional concentrations of
swallows and pigeons.
d. BASH PHASE II - In effect from April to June and
September to November. This phase represents heavy bird activity
associated with the migratory season. Dyess AFB (KDYS)
experiences large concentrations of migrating swallows,
meadowlarks, large raptors and blue herrings during this phase.
Although most of these birds are smaller in size, they pose a
potential threat due to their numbers. While the USAF Bird
Avoidance Model has the area in and around Dyess AFB (KDYS) in
the MODERATE Phase for most of the fall and winter, our local
historical bird strike data shows a dramatic increase in bird strikes
during the Phase II season. Use caution during this phase,
especially when transitioning at night.

6. CUSTOMS/INTERNATIONAL WASTE -
a. All aircraft arriving from non-CONUS locations will
require Customs. Dyess AFB (KDYS) will provide Customs

b. All aircraft will contact Security Forces 72 hours prior to
arrival for Customs coordination at DSN 461-2131/2132, C325-
696-2131/2132.
c. Aircraft will contact Base Operations on Pilot to
Dispatcher when aircraft is 30 minutes out.
d. International Waste Disposal inspections are available.
