(batt approx 50 min/day or 20 min/night
DC power supply failure or over voltage detected

note: with electrical circuit failure check fuse

Answer 3

check DC voltage gauge 
check GEN pushbutton ON
reset GEN 
- if unsuccessful, shed Gen circuits
continue flight - monitor voltage (min 22 volts)
land asapl

5000’ max if boost pumps off

Question 4

HORN

horn sounds when (4)

Answer 4

check horn pushbutton ON
horn sounds:

with HDY caution light when HDY Pressure drop < 30 bar
when N2 between 250-360 (continuous)
when Nr > 410 (intermittent)
when testing cw/l panel with rotor >350 Nr

Question 5

DOORS

Answer 5

reduce airspeed to 120 kts 
visually check doors
if open or unable to check, land or 
continue flight at reduced speed
maintain low slink rate and flat landing approach

Question 6

ENG CHIP

Answer 6

land ASAP

Question 7

TGB CHIP

Answer 7

land ASAPL

avoid prolonged hovering

Question 8

MGB CHIP

Answer 8

reduce engine power
monitor MGBP and MGBT lights

if MGBP light ON - reduce power - land ASAP
if MGBT light is ON -
press CWP Test to check MGBP light
if light does not illuminate - land ASAP
if light illuminates - land and check MGB oil level
if normal - fly to nearest base

Question 9

MGB P

min gb pressure

Answer 9

reduce power - land ASAP

Question 10

MGB T

max gb temp

Answer 10

press CWP Test Switch to check MGBP light
if light does not illuminate - land ASAP
if light illuminates - land and check MGB oil level
if normal - fly to nearest base

Question 11

BATT (yellow)
battery isolated from DC network
no longer charging

for batt only DAY ops
battery, fuel pumps, vhf, radio/nav

Answer 11

check battery pushbutton ON continue flight, monitor voltage

Question 12

BATT T (red)
max batt temp

Answer 12

switch battery OFF

land ASAP

Question 13

PITOT

Answer 13

check pushbutton ON

monitor IAS

Question 14

BLEED V
illuminates (BV open) when Ng < 93%
extinguishes (BV closed) when Ng > 97%

Answer 14

FLAG ON: BV remains closed with Ng < 93%
- possible surge or flameout
FLAG OFF: BV remains open with Ng > 97%
- increases fuel consumption & may limit power available
avoid fast power changes - land ASAPL

Question 15

ENG P

Answer 15

reduce power

check Engine Oil Pressure Gauge
if LOW or ZERO read Torquemeter
if Tq very low shut down engine 
if Tq correct land immediately 
if EOP and TQ correct - land ASAP

Question 16

Low Engine Oil Pressure on Guage

Answer 16

test EOP light in C/W Panel
if light does not illuminate:
check Tq reading
if Tq reading too low - shut down & autorotate
if Tq reading correct - land ASAP
if light illuminates
check Tq reading
if Tq reading too low - land ASAP
if Tq reading correct - land ASAPL
monitor ENG P light

Question 17

Engine Oil Temp High on Gauge - Low Speed/Hover

temp > 110C

Answer 17

land, shutdown, check cooler fan operation
if landing impossible, increase speed to 80 kts
temp should reduce - if not land ASAP

Question 18

Engine Oil Temp High on Gauge - in flight

(temp > 110C) has

Answer 18

reduce speed to 80 kts

temp should reduce - if not land ASAP

Question 19

Fuel Filter
 (clogging - impending bypass)

Answer 19

reduce power
if light goes out - continue flight at reduced power
if light stays on - land ASAP

Question 20

Fuel Pressure Gauge

LOW or ZERO

Answer 20

check fuel filter warning light

if fuel filter light OFF - continue flight (gauge failure)

if fuel filter light ON - reduce power
if light stays on - land ASAP
if light goes out - continue flight at reduced power

Question 21

Fuel

Answer 21

quantity < 60 L
B2 - 18 min at MCP

avoid large changes in attitude

Question 22

Fuel P
fuel pressure lower than 2 bar
on either or both pumps.

Answer 22

check fuel pressure gauge

if pressure normal, continue flight
1 pump failure
if pressure zero, continue flight below 5000”
(2 pump failure)

Question 23

Airframe Fuel Filter

Answer 23

check fuel pressure gauge

if pressure normal, continue flight

if pressure decreases, continue flight less than 5000 ft

Question 24

Low Inlet Pressure Annunciator

light with unexplained increase in T4
dirty/blocked filter, BV failure, poor turbine
t/o with light on prohibited

Answer 24

ENG ALT Air Switch - OPEN
if light extinguishes continue flight
service prior to next flight
if light stays on, monitor eng instruments
if pwr required can be achieved, continue flight, service prior to next flight
if pwr required cannot be achieved, land ASAP - service filter and do power check
