Cross-Country Flight Planning

Objective

Upon completion of this lesson, the student will be able to plan a complete VFR cross-country helicopter flight with 100% accuracy, including route selection through complex airspace, performance calculations, fuel planning with reserves, and risk assessment. The student will demonstrate proficiency in using aeronautical charts, Chart Supplement data, and electronic flight planning tools to create a comprehensive navigation plan that meets all regulatory requirements per 14 CFR Part 91 and ACS standards FAA-S-ACS-15 PH.I.D.K1-K6, PH.I.D.R1-R7, and PH.I.D.S1-S5.

Content

Route Planning and Navigation Systems (PH.I.D.K1)

Cross-country flight planning for helicopters requires careful consideration of airspace complexity and unique helicopter operational requirements. Unlike fixed-wing aircraft, helicopters can utilize low-level routes and operate in confined areas, but this flexibility requires enhanced situational awareness.

Airspace Classification Review:

• Class A: 18,000 MSL to FL600, IFR only
• Class B: Major airports, surface to 10,000 MSL typically, two-way radio required
• Class C: Busy airports, surface to 4,000 AGL typically, two-way radio required, mode C transponder
• Class D: Towered airports, surface to 2,500 AGL typically, two-way radio required
• Class E: Controlled airspace not A, B, C, or D - most common for cross-country
• Class G: Uncontrolled airspace, surface to 700/1,200 AGL in most areas

Special Use Airspace (SUA) Considerations:

• MOAs (Military Operations Areas): Published times, contact controlling agency
• Restricted Areas: Check operating times in Chart Supplement, avoid when active
• Prohibited Areas: No entry ever (P-56 around Washington DC)
• Alert Areas: Unusual aerial activity, exercise caution
• Warning Areas: Offshore, hazardous activities

Navigation System Selection: Helicopters typically use combinations of:

• GPS (primary): WAAS-capable preferred for approach capability
• VOR navigation: Backup system, check NOTAMs for outages
• ADF: Limited use, mainly for approaches
• Electronic Flight Bags (EFBs): ForeFlight, Garmin Pilot for flight planning

Altitude Selection Factors (PH.I.D.K2)

Helicopter altitude selection involves unique considerations not applicable to airplanes. The relationship between altitude and autorotation capability is critical for route planning.

Autorotation Requirements: Helicopters must consider forced landing options continuously. Select altitudes that provide:

• Adequate height for autorotation energy management
• Suitable landing areas within gliding distance
• Avoidance of the “dead man’s curve” (height-velocity diagram limitations)

VFR Cruising Altitudes per 14 CFR 91.159:

• Magnetic course 0-179°: Odd thousands plus 500 feet (3,500, 5,500, 7,500)
• Magnetic course 180-359°: Even thousands plus 500 feet (4,500, 6,500, 8,500)
• Below 3,000 AGL: No altitude requirements

Terrain and Obstacle Considerations:

• Maintain 500 feet above highest obstacle within 1,000 feet of flight path (14 CFR 91.119)
• Consider MEF (Maximum Elevation Figures) on sectional charts
• Account for antenna farms, wind turbines, and unmarked obstacles

Wind Effects on Altitude:

• Higher altitudes generally have stronger winds
• Consider headwind/tailwind components for fuel planning
• Account for turbulence in mountainous terrain at various altitudes

Flight Calculations (PH.I.D.K3)

Accurate calculations form the foundation of safe cross-country flying. Helicopters have different performance characteristics requiring specific calculation techniques.

Time, Distance, and Speed Calculations:

• Time = Distance ÷ Groundspeed
• Distance = Time × Groundspeed
• Groundspeed = True Airspeed ± Wind Component

True Airspeed Calculation: TAS = CAS × √(ρ₀/ρ) where density decreases approximately 2% per 1,000 feet

Wind Triangle Solutions: Use E6B computer or electronic calculator for:

• Wind correction angle (WCA)
• Groundspeed
• Heading corrections

Estimated Time of Arrival (ETA):

• Convert local times to UTC by adding appropriate offset
• Account for time zone changes during flight
• Update ETAs based on actual groundspeeds

Fuel Calculations: Calculate total fuel required:

1. Flight fuel: (Flight time in hours) × (Fuel consumption rate GPH)
2. Reserve fuel: Minimum 20 minutes at normal cruise consumption (14 CFR 91.151)
3. Taxi fuel: 5-10 minutes depending on airport complexity
4. Contingency fuel: 10-15% additional for unexpected conditions

VFR Flight Plan Elements (PH.I.D.K4)

Per 14 CFR 91.153, VFR flight plans are required for flights over water beyond power-off gliding distance from shore, but recommended for all cross-country flights.

Required Elements:

1. Aircraft identification
2. Aircraft type and equipment
3. Departure airport
4. Route of flight
5. Destination
6. Estimated time en route
7. Fuel on board (in hours)
8. Alternate airports
9. Pilot information (name, address, telephone)
10. Number of persons on board
11. Color of aircraft

Flight Plan Procedures (PH.I.D.K5)

Filing Options:

• FSS: 1-800-WX-BRIEF or online at 1800wxbrief.com
• ForeFlight, Garmin Pilot, or other EFB applications
• DUATS (if still available)

Activation:

• Must activate within one hour of proposed departure
• Call FSS or activate through radio
• Flight plan automatically activated when departing towered airport

Closing:

• Must close within 30 minutes of ETA or search and rescue initiated
• Close with FSS, destination tower, or through radio
• Cannot close automatically at towered airports

Inflight Intercept Procedures (PH.I.D.K6)

If intercepted by military aircraft:

1. Maintain steady course and altitude
2. Follow intercepting aircraft
3. Land at nearest suitable airport
4. Contact ATC or FSS immediately upon landing

Instructor Actions

1. Begin lesson by presenting real-world scenario: “Today we’re planning a flight from [local airport] to [destination 150+ nm away] departing at 10:00 AM. This flight will take us through Class C airspace, over mountainous terrain, and requires careful fuel planning.”

2. Demonstrate sectional chart analysis: Point out Class B/C airspace boundaries, restricted areas, and terrain features. Show how MEF figures relate to altitude selection.

3. Explain helicopter-specific altitude considerations: “Unlike airplanes, we must always consider autorotation landing sites. Notice how this route keeps us within gliding distance of suitable terrain.”

4. Guide student through wind triangle calculation: Use E6B computer to solve for heading and groundspeed with given wind conditions. Emphasize accuracy in measurements.

5. Demonstrate fuel planning methodology: “Our helicopter burns 20 GPH at cruise. For a 2.5-hour flight, that’s 50 gallons flight fuel, plus 7 gallons reserve, plus taxi fuel.”

6. Show proper Chart Supplement usage: Look up destination airport information, fuel availability, services, and any special procedures or restrictions.

7. Walk through VFR flight plan form completion: Fill out each block while explaining significance and requirements.

8. Demonstrate EFB flight planning features: Show route planning, weather overlay, NOTAM integration, and fuel calculation tools in ForeFlight or equivalent.

9. Conduct risk assessment using PAVE model: Systematically evaluate pilot, aircraft, environment, and external pressures for the planned flight.

10. Present fuel recalculation scenario: “Weather now shows 30-knot headwinds. Recalculate fuel requirements and determine if additional stops are needed.”

11. Review intercept procedures: Explain recognition of military interceptors and appropriate pilot responses.

12. Assign student practice problem: Provide different route and conditions for independent planning with instructor monitoring.
