2P board #2 Flashcards
Def. of warning
Explanatory information about an operating procedure, practice, or condition that may result in injury, death, or loss of aircraft if no carefully observed
Shall
used only when application of a procedure is mandatory
Land as soon as practicable
Extended flight is not recommended. The landing site and duration of flight are at the discretion of the pilot in command
5 steps in emergency
Maintain control of the aircraft
Alert crew
Determine the precise nature of the problem
Complete the applicable emergency procedure or take action appropriate for the problem
Determine landing criteria and land as required
Cycle
If the circuit breaker is in, pull circuit breaker out, and then push circuit breaker back in. If circuit breaker is out, do not change condition.
Reset
If circuit breaker is out, push circuit breaker in. If circuit breaker is in, do not change condition
Max number of people in cabin
3, Can do more for emergency/SAR
Starter limits
OAT <16, on off 60 sec
on - off 60 sec
on - off 60 sec
on - off 30 minutes
OAT 16-52 on - off 60 sec
on - off 30 minutes
Start cycle defined as starter initiation, acceleration, and dropout
Backup hyd pump limits
With rotors static
OAT 33-38
24 on 72 minutes off
39-60
16 on 48 minutes off
Compressor section
5 stage axial and a single stage centrifugal rotor/stator assembly
Airflow of combustion
30% of total airflow for combustion
70% T2 P3 Combustor and turbine cooling engine oil seal pressurization
C-PWR
Sets max permissable TGT to 903, limits at 891+_10
Auto C power turns C power on when one engine is below 50% torque, opposite engine sets max of 891+_10
TGT limiting
When TGT approaches 878 EDECU prevents any further fuel flow. MRP prevents at 866+_10
LDS Malfunction
Roll pin failure or LDS cable malfunction
PCLs in idle - Ng 3-4 percent higher than other engine
PCLs fly collective full down - 1-2 percent torque diff, Nr and both Np 1-2% above 100
In flight - notice torque splits for certain flights, collective increase/decrease below 75%
Utility Module
Routes fluid from backup pump to 1 and 2 transfer modules, second stage of the tail rotor servo, rescue hoist, APU accumulator
Priority valve secures power to rescue hoist in the event backup hyd pressure decreases
Velocity fuse secures fluid to APU accumulator if flow rate exceeds a prescribed limit
Engine anti-ice/Start bleed valve
5th stage bleed air to the engine
Open during starts
Closes above 90 percent Ng
Can flameout engine with a temporary hangup of variable geometry with low collective settings
Malfunctioning ON with above 90 Ng or above 94 Ng if OAT greater than 15 Not ON below 88 Ng Not ON with switch being turned on No rise in TGT with switch ON
May reduce max torque by 18%
How to conserve fuel
Single up
Climb and slow up
Fly at max endurance
ECS - off
Contaminated fuel
Water contaminated fuel may cause fluctuations/surges in one or both engines
SEL JETT aux tank
Tank will not jettison for ALL STORE JETT if less than 40 gallons (272 lbs) fuel gauge in 50 pound increments so less than 300 must SEL JETT
1 Fuel Low
One tank less than 300 pounds
Land as soon as practicable
W: less than 600 pounds of fuel, fuel starvation may occur when balanced flight is not maintained and pitch exceeds 15 degrees
Categories of fuel
Primary-authorized for unrestricted use
Restricted- imposes operational restrictions
Emergency - may be used for a minimum time when no other primary or restricted fuel is available in case of emergency or operational necessity
Jet B / JP-4
Restricted fuel
Fuel is susceptible to icing
Static rollover
28 degrees
TGT in a hover
Saltwater power deteriation
Rise of 20 is an indication of degradation and possible salt encrustation
Rise of 40 for a constant torque is an indication of engine performance degradation, which may result in compressor stall
1 Input Chip
Main transmission malfunction emergency procedure-perform
Note: consideration should be given to returning the engine PCL to fly for landing
80T-122 permissable Lighting degredations aided
May be conducted in the event of a failure of more than one of the lighting subsystems required for ship’s facility certification provided all of the following criteria are met:
Visible horizon exists and is discernible through NVDs by HAC
Ships CO and Det OIC concur that the failed systems are not critical
Following have not failed
Overhead/forward structure floodlights
Deck surface/hangar wash floodlights
Associated lighting control panels
80T-122 permissable Lighting degredations unaided
Night unaided may be conducted in the event of a failure of not more than one lighting subsytem if
Visible horizon exists and is discernible through NVDs by HAC
Ships CO and Det OIC concur that the failed systems are not critical
