d. N Ramp:
(1)
Aircraft must stay on the taxi lead-in line while on this ramp, to avoid taxiing over deteriorated pavement.
e.
All jet aircraft are prohibited from taxiing or conducting engine runs on the asphalt portion of the E and W ramps due to the deteriorating pavement.
f. General information:
(1)
The tower will advise C-130 and larger aircraft to taxi with outboard engines at idle.
(2)
Turns be made to avoid blowing foreign object damage into the arm/de-arm (Rwy 08 requires a right 180° turn at end of runway, Rwy 26 requires a left 180° turn at end of runway).
(3)
No aircraft shall be taxied, towed or parked behind aircraft larger than a C-130 (within 1000’) while the engines are running.

2. CAUTION -
a. BIRD ALERT - Large concentration of birds in vicinity of airfield during inclement weather. Expect bird flocks on and in vicinity of Langley AFB (KLFI) during migratory season and intense bird activity. Fall migration S begins in October with the peak period between November-February. Peak spring migration N runs from February-April. Expect short notice Bird Watch Condition SEVERE and/or short term airfield closure.
(1)
Bird Watch Condition SEVERE. Heavy concentration of birds on or immediately above the active runway or other specific location that represents an immediate hazard to safe flying operations. First Fighter Wing aircraft will not normally conduct operations in an area declared SEVERE. The area declared SEVERE shall be open only by specific pilot request and after thorough evaluation of mission requirements. All aircraft should delay departure, arrival or divert until the condition is downgraded. If F-15 and F-22 landings are directed or must be made, plan on full stop single ship landings. Non-first Fighter Wing aircraft will be advised of the Bird Watch Condition and asked to state their intentions.
(2)
Bird Watch Condition MODERATE. Concentrations of birds observable in locations which represent a probable hazard to safe flying operations. This condition requires increased vigilance by all agencies and extreme caution by aircrews. If possible, departure paths should be planned to avoid bird concentration areas and the necessity to conduct multiple approaches should be thoroughly evaluated. F-15 and F-22 formation takeoffs, approaches, and landings are not authorized. Non-first Fighter Wing aircraft will be advised of the Bird Watch Condition and asked to state their intentions.
(3)
Bird Watch Condition LOW. Normal bird activity on and above the airfield with a LOW probability of hazard.
b. SPECIFIC HAZARDS IN THE LANGLEY AFB (KLFI) AREA
-
Seagulls provide the largest threat to flight operations in the airfield area. Several subfamilies are permanent residents of the bay area and others pose a migratory hazard as well. Langley AFB (KLFI) lies along a major migratory route and its open spaces attract numerous species for rest and feeding. Large game fowl transit the area seasonally and are particularly dangerous because they fly at night, at altitudes below 10,000’ AGL. Much of this activity is observable on radar. Migrating waterfowl are particularly dangerous to flight safety due to the large numbers and generally higher altitudes flown by waterfowl enroute to breeding and wintering grounds during spring and fall. Huge flocks may stop along the route awaiting favorable weather conditions to continue. Migrating birds are most active from sunset through midnight, with numbers decreasing in the early morning hours. October and November are the most hazardous months. Prudent flight planning can especially reduce the exposure to bird strikes from large birds between mid-September and early December.
