3 Fundementals Skills Of IFR Flight
1. Instument Cross Check/Scan
2. Instument Interpretation
3. Aircraft Control
2 Control Instuments
1. Attitude Indicator
2. Manifold Pressure Guage
Manifold Pressure Settings For Desired Airspeed
1. 18-19" = Straight/Level @ 90 Kias
2. 21-22" = Straight/Level @ 110 Kias
3. 15-16" = 500 FPM ROD @ 90 Kias
4. 13-14" = 1000 FPM ROD @ 90 Kias
5 Performance Instuments
- Tells What The Heli Is Doing &
- Is It Doing What We Want

1. ASI - Airspeed Indicator
2. TC - Turn Coordinator
3. HI - Heading Indicator
4. VSI - Vertical Speed Indicator
5. ALT - Altimeter
Main Scan
(Selective Radial Scan)
AI-ALT-AI-VSI-AI-HI-AI-TC-AI-ASI-AI
Secondary Scan
- About Every 3rd (Main)Scan
- Do A Secondary Scan

1. Manifold Pressure Guage
2. All Other Guages & AUX Indicators
- Temperature Guages
- Fuel Guages
- GPS
- Warning LTS
- ETC...
T Scan
- Used To Minimize Wordload
- Every 3rd T Scan Include VSI & TC
AI-ALT-AI-HI-AI-ASI-AI
Turns
- All Turns @ Standard Rate
-> Standard Rate = 3 Degrees Per Second

1st Check The AI
-> Cherry Must Be On Horizon To Initiate Turn

AI-TC-AI-HI-AI-VSI-AI

- VSI Becomes Primary Guage For Pitch Info In Turns
-> B/C AI Is Suseptable To G-Forces & Gyro P.

*Roll Out 1/2 The Bank Angle Prior to The New Heading
Descents
1. Start @ Manifold Pressure Guage
-> Set @ 15-16" For 500 FPM ROD
2. Scan AI
- Wings Level
- Now AI Is Primary Guage
3. Scan ASI
- Pitch Fo 90 Kias
- Back To AI
4. Scan VSI
- @ Least 500 FPM ROD
- Back To AI
5. Scan ALT
- Desired ALT??
- Back To AI
6. Scan HI
- Desired Heading??
- Back To HI

NOTE:
Level Out @ 10% Of The Descent Rate Prior To Desired ALT
- IE: 15-16" = 500 FPM ROD: Level Off @ 50 Ft
- IE: 13-14" = 1000 FPM ROD:
Level Off @ 100 Ft
Climbs
- Set The Manifold Pressure Setting To Max Continuous Power (MCP)

1. Scan AI
- Level Attitude @ Starting ALT
2. Scan VSI
- Pitch For Rate Of Climb (ROC) @ Least 500 FPM
- Back To AI
3. Scan ALT
-
- Back To AI
4. Scan ASI
- Pitch For Desired Airspeed (60 Kias)
- Back To AI
5. Scan HI
- To Keep Desired Heading
- Back To AI
Inverted V Scan For Broken Instument Check
- Used To Determine Broken Instument
- Check For Power Failure Of 1 Of 3 Power Sources

NOTE:
3 Power Sources:
1. Pitot/Static
- ASI, VSI, ALT
2. Electical
-
3. Gyro
- AI, TC, HI

Inverted V Scan
1. Start @ The AI
- Primary V Scan Guage
- Seperate Power Source
2. Scan TC
-
- Seperated Power Source
- Back To AI
3. Scan VSI
-
- Pitot/Static System
- Back To AI
3 Problems With Scanning Methods
1. Fixation
- Biggest Of The 3
- Fixation On One Instument
Correction:
- Rememeber To Keep Scan Moving

2. Miss-Interpretation
- Reading Instument Wrong
-
Correction:
- Practice & Think

3. Skipping An Instument
- Most Commonly Skipped Instument Is The AI
-
Correction: Develope Good Scanning Habits
INCREASE THE SCAN
NOTE:
Anytime You Feel Something Is Wrong:
- INCREASE THE SCAN -
