Explain Class I & Class II Navigation
–Class I

–Class II
•Any enroute operation not defined as Class I navigation.

Each individual procedure conducted during Part 135 IFR flight, must be explicitly approved through operations specifications.

–Part 29
•Certification of Transport Category Rotorcraft
–91.205(d)
•Aircraft Minimum Equipment Requirements
–Rotorcraft Flight Manual
•Chapter 1, Limitations
•RFMS
•Minimum Equipment List
What equipment is required by part 91 for IFR?
GRABCARDD
–Generator
–Radio/Nav Equipment
–Altimeter - Sensitive and adjustable
–Ball - inclinometer
–Clock - Hours, minutes, seconds, or digital
–Attitude Indicator - Pitch and bank
–Rate of Turn Indicator - Turn coordinator or turn indicator
–Directional Gyro - Gyroscopic compass
–DME - For flight above 24,000ft (FL240)
If there is inoperable equipment found prior to flight, how should that be handled?
Consult with maintenance & MEL
What checks should be completed prior to crossing any waypoint en-route or on approach, anytime you receive an ATC clearance, or anytime you feel a little overwhelmed?
SIX T’s:
Turn - course or heading
Time - start/stop timer as needed
Twist - heading bug or CDI change
Toggle - Mode Select Panel, GPS sequence, FD changes, etc
Throttle - target altitude
Talk - ATC or copilot comms/requests
What are the Non-flying-pilot callouts that should be briefed?
Waypoints
- Call out 2NM, 1NM, and 0.5NM from waypoints. The 2NM call is often omitted during
approach phases due to proximity of waypoints and workload.
Course and Heading
- Readback all ATC Courses and Headings. The flying pilot will then repeat the clearance over
ics, confirming they heard the instructions and have set their HSI accordingly.
Call out any deviations beyond 5 degrees off course or heading.
Altitude
- Readback all ATC altitude clearances. The flying pilot will then repeat the clearance over ics, confirming they heard the instructions and have set their VSI Bug, Altitude Hold, or manual climb gradient accordingly.
- Call 500’, 200’, and 100’ increments, prior to reaching assigned altitude.
- Call out any deviation beyond 50’ off assigned altitude.
Airspeed
- call out Vtoss, Vy, and target airspeeds as applicable
- call out any deviations of 5 knots from target airspeed
What briefing should be completed prior to reaching IAF?
IMARTHA
Identify the plate
Missed approach procedure
Atis information
Radio frequencies, nav and comm
Timed approach
Heading of final course
A Ititude of MDA or DA
ICE ATM
Identify - frequency & Morse or load GPS approach
Course - set inbound course, external annunciator
Entry - full or vectored
Altitudes - initial, step downs, MDA/DA
Time - if needed
Missed - run through inductions
WISP
Weather - obtain
Instruments - verify
Stack - verify avionics
Procedure - brief
What is the DECIDE model?
•Detect
•Estimate
•Choose
•Identify
•Do
•Evaluate
Com failure
–Check systems first
–The problem usually sits in front of the radio
–Transmit into the blind
–Squawk 7600
–VMC: remain in VMC and land as soon as practicable
–IMC “AVE-F MEA”
91.185 – AIM 6-4-1
What route & altitude should be flown if lost coms IFR?
•Fly the route (in this order)…
–Assigned – as in your last clearance
–Vectored – to where you were being vectored
–Expected – what you were told to expect
–Filed – what’s on your flight plan
•Altitude (the highest)
–Assigned
–MEA
–Expected
How far can you continue along your route with lost coms? (ie clearance limit)
IF clearance limit is an IAF
–Hold at the clearance limit
–Start descent at EFC or ETA
IF clearance limit is not an IAF
–EFC time – leave at EFC to an IAF and begin approach
–No EFC time – proceed to an IAF
–Start your approach as close as possible to the ETA
Gyroscopic Instrument Failure
–Fly the aircraft
–Identify (and cover) the affected instruments
–DECLARE EMERGENCY!
–Report and request assistance
–Fly timed turns
–Request MVA
–Request vectors to VFR conditions
What’s the minimum airspeed in IFR for the 107?
55 kias
Transitory during takeoff for IFR in IMC: 40
What is the max airspeed for IFR operation in IMC in a 107?
120 or Vne (whichever is lower) limit in GOM
(125 kias or Vne limited in RFMS 7)
Airspeed limits for IFR operation:
Transitory Vmini IMC takeoff 40 KIAS
Vmini IFR in IMC 55 KIAS
CHI company Vne 120KIAS
Vne for IFR ops in IMC 125 KIAS
-Further limited by company Vne
-Further limited by DA (RFM Vne chart)
What are the flight restrictions & limitations for flying the 107 under IFR?
•SAS must be operational
•Speed trim must be operational
•Cyclic Mag brake must be engaged during all IFR IMC flights
•Flight into IMC with inlet screens installed prohibited with OAT 5C or less
•10 degree yawed climb prohibited under IFR conditions
•Bank angles in excess of 30 degrees prohibited
•Rate of descent in excess of 1000 feet per minute prohibited when operating under IFR conditions
SAS failure
Reduce speed to 80 kts or less
Never closer to Vne than 10ths
Be cautious of 55 kr Vmini
Don’t exceed bank angle of 5 degrees
AC and DC Fail
•Unlikely
•Aux bat can power stby attitude indicator
•90 minutes if fully charged
•9 more minutes with no power
•Equipment blower fan light on canted console
What are the requirements for multi engine helicopters to conduct IFR over the top?
Multi engine helicopters carrying passengers off-shore must be able to climb at least 50 fpm with OEI at MEA or 1500 msl. 135.181
VFR ON TOP
IFR flight plan, while remaining in VFR continuous
All ATC for clearance for
VFR over the top
No clearance required
Visual contact with the ground not required
VFR cloud clearance must be maintained
CHI GOM permits
- if forecast is VFR @ ETA & 1 hour after
- must be able to maintain OEI
135.181
- requires single engine climb of 50 fpm at MEA or up to 5000 ft
- multi engine helicopters carrying pax over water 1500 msl OEI maintain 50 fpm climb
