Normal Procedures Flashcards
Daily Inspection
In-flight pitot and anti-ice.
What gauge changes when on?
Turn on in visible moisture and OAT < 4.4C
TOT will increase when anti-ice is on.
Prolongued low-power approaches
During prolonged low power approaches, RPM overspeed may occur (due to flat pitch)
- Control by slight increase in collective and/or beep N2 back down to 100%
- Remember to beep N2 back up as collective is applied
Fuel drain procedures
FUEL SUMP
- Boost Pumps —– OFF
- Fuel valve —– OFF
- Battery —– ON
depress fuel drain and take sample
A/F FUEL FILTER
- Fuel valve —– ON
- Boost Pumps —– ON
- Caution lights —– ON
open filter drain valve and take sample
- Fuel valve —– OFF
- Battery —– OFF
Abort Start
Starter —– keep pressing
Idle release —– press and close
[ING ENG] —– Pull if you have time
Wet Start/Hung Start
Hung start = engine fails to accelerate and RPM stays low. Uses up battery, engine slows, combustion chamber becomes hot
Wet start = flooded engine and igniter failed to light fuel. Wait > 5 min and vent engine. Use APU next start.
Make sure throttle is FULLY CLOSED before hitting starter to avoid a hot start.
N1 value to hit starter?
12% (OAT < -18C)
13% (-18C < OAT < 7C)
15% (7C < OAT)
Starter limitations 206 B
Starter Cranking after Shutdown
To avoid overheating, limit starter energizing times (battery):
ON 40 sec, WAIT 60 sec
ON 40 sec, WAIT 60 sec
ON 40 sec, WAIT 30 min
Cranking engine to force cooldown after shutdown is only acceptable if another start is required and TOT > 150C
(forcing cold air through hot engine can cause cracking from thermal shock)
How to identify a weak battery
If battery is charged, there will be < 1% change in loadmeter when BATT is switched off
Monitor fuel pressure as you press starter. If it drops to zero, battery is weak.
If load meter remains high during flight, possibility of a short circuit
Power check procedure
[ANTI-ICE] [GEN] —– off
Collective —– Raise to TQ or TOT limit
Record —– OAT, TOT, PA, TQ, N1
May be performed in a hover, in stable 60 mph (52 kt) climb, or in level flight
- Only conduct in hover if altitude, temp and gross weight permit safe hovering height.
- More accurate checks above max cont TOT (738), which generally means being >5000’ to avoid exceeding TQ limits
T/O power limits:
- Max TQ: 100% (5 min)
- Max TOT: 810 (5 min)
- Max N1: 105%
CONFINED AREAS - How to check hover power before landing
Fly straight and level at 70 kts ~500’ AGL.
- you will need +20% TQ to hover IGE
- you will need +30% TQ to climb back out
If adding passengers or luggage, add 3% TQ for every 100 lbs
CONFINED AREAS - Recce and Exiting
High Recce- flown at 1000’ AGL
- General suitability
- Power available
- Wind
Low Recce - flown at 3-500’ AGL
- Size
- Shape
- Surrounds
- Sun
- Surface
- Slope
- Wind
- Wires
- Wubbish
If high winds, only to recce into wind (not downwind)
When exiting, try not to pull full pitch unless necessary –> If engine fails, higher pitch bleeds RPM faster (more drag)
Before Starting
- Check weather and legal dark (if applicable)
- Check next due on flashcard
- Open Flight Itinerary
- GW and CG calculations (get passenger weights, etc)
- Connect battery
- Complete DI (exterior and interior)
- Passenger briefing
- Logbook, first aid kit, survival kit, startstick, tie downs, plugs, zoleo, ipad and charger onboard
