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 - |
