6112A Flashcards
Scope of the NATOPS
contains flight clearance information, operating procedures and restrictions necessary for flight crews to effectively operate their aircraftno manual can address every situation completely or be a substitute for sound judgement
Takeoff power max
4700 hp at temps up to 39.4*C (104*F) at sea level no bleed air
max continuous power
4700 hp at 28.3*C (83*F) sea level with both a/c packs on
Overspeed protection
- Np >104.5% the overspeed governor diverts oil from PCU to increase blade angle and control overspeed
- Np >106% fuel flow is decrease
- Np >119% the FADEC shuts down the engine
- Ng >109% the FADEC shuts down the engine
AFCS Basic Operation
- -Used for 4-,3-engine operation during climb, cruise, descent and approach
- -Capable of intercepts of 90* (75* loc BC) 45*preferred
- -Autothrottles will not allow speed below 1.2 Vs
Autopilot Limitations
- T/o and LDG
- A/S > Vh
- ILS Below 200’ HAT, Below MDA on NPA, over localizer
- IPRA below 200’ HAT
- At or below 500’ non-app operations
- RVSM ALT plus/minus 65’
- Weight >164,000 lbs below 1,000’ AGL, config changes or approach operations
3 distinct phases of emergencies
- Establish and maintain A/C control, flt path clear of terrain, identify and verify nature of malfunction and complete memory items
- Complete ACAWS crew action items, engine-out considerations, determine COA (continue, mission abort, return to base/divert, etc.) and brief the plan
- Monitoring/managing degraded systems, prepare fro unscheduled LDG if necessary, employ crewmember at ACS`
Immediate actions and stabilization during emergency
- Regardless of altitude PF keep controls and maintain safe flight path until immediate action items are completed- <1000 AGL
- PM announce nature of malfunction (engine failure) and perform duties as required
- >1000 AGL PM state precise nature of malfunction (gearbox No. 1 no oil pressure), PF shall verify and verbally confirm malfunction, AC then calls for appropriate checklist/crew action
- AC should assume role of PM
Takeoff Abort Criteria<70 kts
- Abort if a major condition arises
- Abort with WARNING-CAUTION ACAWS
- Abort with any ADVISORY ACAWS associated with a malfunction
Takeoff Abort Criteria>70kts to V1 (Vref)
- Abort if a major condition arises
- Abort for a MASTER CAUTION/WARNING AURAL and VISUAL ALERT that threatens takeoff
- Abort for an engine failure, fire or serious directional control problems exists
Takeoff Abort Criteria>V1 (Vref)
- Continue takeoff unless airworthiness of A/C is in jeopardy
