• "Cabin Altitude" (CAWS)
" annunciates through CAWS and headsets when cabin altitude increases between 10,000 - 12, 500 ft, when this happens aircraft should automatically deploy oxygen masks and following occurs: o Passenger oxygen mask boxes #1 & #28 open (contain prox sensor) o EMER OXY ON illuminates at FWD LM station (amber light above LM's oxygen regulator) o Cabin lights come on full bright white (incandescent and fluorescent) o Cargo compartment warning horn sounds (beeps until LM silences, Warning horn silenced with switches at FWD LM Station and AFT LEFT LM Station) o Personnel advisory signs come on (Seat Belt/No Smoking Signs) o RETURN TO SEAT message in Lavatory is inhibited (stays off due to masks being available in lavatory) o Two Green flow lights illuminate for sidewall and centerline seats at Fwd LM Station o Oxygen flow to passenger masks automatically starts to decrease when cabin altitude descends thru 10,000 feet o Oxygen flow to passenger masks should automatically shut off when cabin altitude reaches approx. 8,500 feet • Oxygen flow to passenger masks can be shut off manually using -1 emergency regulators (PULL TO SHUT OFF LEVER) or -501 Sidewall emergency regulators (move toggle stop to OFF) o Cabin lights remain full bright until mask containers 1 & 28 are closed o Following an intentional cabin depressurization above 10,000 feet, the cabin must be repressurized to less than 3,500 feet to reset the regulators. If the regulators are not reset, subsequent flight above 9,000 feet cabin altitude may deploy the passenger oxygen masks.

Packs -
• If one AC pack fails, the other will back it up • Hi-flow switchlight commands both AC flow control valves to high • Valves are normally set low/inflight and high/ground • Flow control valves fail to High Flow setting if electrical power is lost and bleed air is still avail • Compartment Air Flow Switchlight provides means to shut off conditioned air to flight deck, crew rest and cargo compartment without affecting avionics cooling in the event the aircraft becomes contaminated • Avionics Cooling Override Switchlight used to override controls of avionics cooling augmentation valve. When pressed, avionics outflow valve and avionics augmentation valve are driven open and ESC shifts both AC packs to high flow and sets left pack discharge temp to 40 +5 degrees
4) Hazardous Materials
• Items with more than one hazardous material or are classed based on the highest hazard presented by the materials or combination of materials.
4. Cargo loading limitations
• Max ACL - 170,900 lbs Non ER, 164,900 lbs ER • Lateral loading limit - 93,000# Lt or Rt of aircraft C/L • Max allowable compartment weight o D/ FS 347-578, 72,000#, E/ FS 578-1074, 170,900#, F/ FS 1074-1165, 35,000#, G/ FS 1165-1403, 40,000#
B. Forklifts
• Minimum tine length - 72" • Only forklifts rated at a lifting capacity equal to or greater than the pallet to be loaded shall be used. • Do not overlap the toes when using rollerized tines • Forklift operations may be performed inside the aircraft provided all Section IV loading/offloading limitations and forklift limitations are not exceeded. • Pallets in 88" orientation will be secured • When bare tine forklift loading, ramp toe rollers shall not be removed while a pallet is positioned over the toes. Ramp toe inner roller channels may only be removed prior to marshalling the forklift into position. • When bare tine forklift loading, outer ramp toe roller channels shall not be removed.
E. ADS rails
• No perm vertical restraint on ramp/last 60" of cargo floor • Rt locks (floor) - 14,800# fwd restraint, 7,500# aft restraint • Lt locks (Rt on ramp)- 14,800# fwd restraint, 15,533# aft restraint • Refer to -9 Table 4C-2 and 4C-3 for ADS rail system pallet(s)/platform(s) restrictions when loaded out of pallet position. • Manual release by removing plugs on top of rails near each lock and pulling cotter pins, Once pulled lock must be re-rigged by maintenance
L. Staging lights
• Operated from LACP • Illuminates 100' radius
C. Air deflectors
• Operation - 1st door, 10-15 degrees, 2nd door fully deploy prior to opening
D. Logistic rails
• PP 1, 7, 8, 9 have 1 lock each side only • No perm vertical restraint on ramp/last 60" of cargo floor • All locks - 20,000# fwd restraint, 10,000# aft restraint • Pallets loaded out of position in the Logistic rails do not have any weight restrictions except for the ramp pallet positions. Refer to -9 Table 4C-1 • Manual release by using tool, Lowers all locks simultaneously for each pallet position
• HYD Components o #1 & #4
• Primary flight controls • Aux pumps in Lt/Rt fwd main landing gear pod
F. Restraint harness/parachute
• Required to be worn when inspecting/opening doors • 2 harnesses stowed in LFCP stowage drawer • Connected to any tiedown ring at/fwd of FS 1188
H. Cargo ramp
• See -9, Figure 4B-1, Ramp Actuator Lifting Capacity • Raised ramp height - 156" hinge to 116" edge, see Fig 4D-9 • Ramp inflight load capacity - 40,000# • Inflight ramp opening - 29,000# (except when jettisoning) • Ramp blowdown - 20,750# • Ground support pad - 18" long x 30" wide
5) Emergency signals
• Six short rings (ditching, crash landing prep) • Three short rings (bailout prep) • Warning horn & "Bail out, bail out, bail out" over PA • One long sustained ring (implementation)
Avionics overheat
• Temperature in inlet rack has exceeded 90 degrees for more than 5 minutes - #2 & #3 load shedding relays trip off and AC/DC Avionics buses depower - Avionics Cool ORIDE Switchlight drives opens avionics cooling augmentation valve and avionics outflow valve - Compartment Airflow Switchlight directs all left pack air to avionics cooling - If overheat persists with Packs On turn avionics check valve handle to open (Fwd LM Station below table on fwd bulkhead)
C. Ramp toes
• The primary method of loading pallets into the ADS and logistic rails system is using the ramp toes. • If the ramp toes and roller conveyors/guide rails are used, ensure they are properly installed. • No cargo aft of FS 1390 with ramp toes installed • Low position, aft end not supported • Toes normally used in pairs (must have sensor - R.O./L.I.) • They can be stowed on the door or in the upright position for flight
O. Bridge plates
• Used for spanning the gap between K-loader and cargo ramp • 7,500# per or 15,000# axle for two
o Fuel-In-Tank Limits
• Will not exceed 3/4 tank capacity when placed on aircraft cargo floor and 1/2 full tank loaded on cargo ramp. • Engine powered wheeled support equipment will not exceed one half full tank. • If palletized, draining is required unless palletized to meet aircraft subfloor requirements. • Equipment mounted on a single axle disconnected from its prime mover and loaded with tongue resting on aircraft floor must be drained (purging is not required). • Engine powered ground support equipment (non-wheeled) must be drained, but no purging is required. This also applies to equipment carried as a "Secondary" load on trailers or vehicles.
