Proceeding Direct to a Point via GPS
OBJECTIVE
Build trainees' ability to integrate GPS navigation for direct routing in a virtual simulator under VFR, combining ground knowledge with practical flight skills to maintain accurate tracks while managing aircraft control and situational awareness.
CONTENT
GPS Setup and Activation
- • Pre-flight: Enter waypoints into GPS unit, verify database currency, and perform RAIM check for integrity.
- • In-flight: Activate direct-to function, set desired track, and monitor CDI for deviations.
GPS SETUP CHECKLIST
□ Database current
□ RAIM check complete
□ Waypoints entered
□ CDI sensitivity set
Flying Direct Routes
- • Maintain heading to follow GPS guidance, adjusting for wind using crab angles; cross-check with ground speed and ETE readouts.
- • Integration with basic control: Hold altitude and airspeed while navigating, scanning for traffic and landmarks.
Scenario-Based Practice
- • Simulate routes to fixed points (e.g., VORs, airports), including en route adjustments for simulated ATC instructions or weather.
- • Multi-leg navigation: Chain direct-to segments, updating waypoints mid-flight.
Error Handling and Backups
- • Respond to GPS anomalies (e.g., signal loss) by reverting to dead reckoning or visual references.
- • Common pitfalls: Over-reliance on automation; practice manual overrides.
GPS FAILURE BACKUP
Revert to: Dead reckoning → Visual references → VOR/NDB if available
SORTIE TASKS
Pre-Sortie
- 1Plan a VFR flight plan with at least one destination waypoint (airport, VOR, or fix)
- 2Enter waypoints into the aircraft GPS and/or tune VOR as applicable; file flight plan on VATSIM and connect
- 3If ATC is online, obtain ATIS and contact Ground/Tower; if not, depart via CTAF self-announce
Sortie
- 4Depart and activate GPS direct-to or center the VOR needle on the planned course
- 5Maintain desired track using GPS/VOR guidance; cross-check with visual references en route
- 6Arrive at destination within 1 NM; update GPS/VOR for return leg or next waypoint
- 7Return to home field using GPS or VOR guidance; contact tower or self-announce as appropriate
Post-Sortie
- 8Full-stop landing and taxi to parking with correct after-landing comms
- 9Log the sortie in the vTAC flight log system
Approved Callsigns
COMPLETION STANDARDS
Trainees will execute GPS direct navigation in the simulator with minimal instructor input. Trainees must:
- • Arrive at waypoints within 1 NM
- • Maintain control tolerances (±500 ft altitude, ±20° heading, ±20 knots airspeed)
- • Handle two simulated failures correctly
Completion: Demonstrate proficiency with instructor sign-off
