Direct to a NAVAID Procedure
Enroute
- Tune, Identify, and Monitor the desired NAVAID
- PFD Source = VOR
- Bearing Pointer #1 = VOR
- Turn the shortest direction to place Bearing Pointer #1 head under the Heading Indicator
- Set the current course in the CDI with the correct “TO” indication (Use the Press & Hold function of the CDI button)
- Track the new course
Tracking Procedure
Enroute
- Establish aircraft on the desired course
- Maintain heading = course until deviation is noted via the CDI center bar and the Bearing Pointer
- Determine Wind Direction using TAIL-RADIAL-WIND
- Turn to re-intercept the desired course using TAIL-RADIAL-TURN (or just turn the direction the CDI center bar is displaced)
- Set crab into wind to maintain course (use HDG bug to bud the WCH)
Six T’s
- TIME: Time could be noted, started, or not needed depending on the situation
- TURN: Turn in the shortest direct to a heading that will parallel or intercept the outbound course
- TIME: Time could be noted, started, or not needed depending on the situation
- TRANSITION: Initiate altitude, airspeed, or configuration transition as required by the situation
- TWISTERCEPT: Set the new course in the CDI with the “FROM” indication (Use the Double-the-Angle method which involves doubling the angle between the tail of the bearing pointer and the head of the new course arrow)
- TALK: Make any voice reports as required
Over-the-Station Intercept Procedure
Enroute
Known as the 6 T’s
- TIME: As required
- TURN: Turn in the shortest direct to a heading that will parallel or intercept the outbound course
- TIME: As required
- TRANSITION: Initiate altitude, airspeed, or configuration transition as required by the situation
- TWISTERCEPT: Set the new course in the CDI with the “FROM” indication (Use the Double-the-Angle method which involves doubling the angle between the tail of the bearing pointer and the head of the new course arrow)
- TALK: Make any voice reports as required
Outbound-Outbound & Inbound-Inbound Radial Intercepts
Enroute
- Tune, Identify, and Monitor the Station
- Set CDI to the new course (if outbound = same at the desired radial——if inbound = reciprocal of the desired course)
- Turn to the intercept heading by turning towards the deviation bar and placing the head of the course arrow in the top half of the HSI on a 45° benchmark
- Maintain intercept heading until you can turn onto the new desired course (when the CDI bar starts to close in)
- Track on the new course/radial
Outbound-Inbound Radial Intercepts
Enroute
- Turn onto new course/radial. Maintain the intercept heading until able to make a SRT onto the new course. The rate of the bearing pointer and CDI movement will increase close to the station due to radial spacing.
- Track on the desired course/radial.
Radial-to-Arc Intercepts
Enroute
- Proceed direct to the arc entry point
- Calculate lead point DME based on what kind of turn you’re using (SRT = 0.5% groundspeed or 1/2 SRT = 1% groundspeed)
- Determine turn direction at lead-point
- Start a SRT at the lead point to place the head of the bearing pointer on the 90° benchmark
How do you increase DME when arcing?
Put the bearing pointer head below the 90° benchmark
How do you decrease DME when arcing?
Place the bearing pointer above the 90° benchmark
Arc-to-Radial Intercepts
Enroute
- Use 60-1 rule to determine the number of radials per mile
- Determine the turn radius of the aircraft for a 90° turn
- Find the lead radial: LEAD RADIAL = LEAD DME x radials per mile
- Start a SRT onto the new course at the lead radial
Point-to-Point
Enroute
- TIM the Station
- Set the desired new radial on the CDI
- Turn to a HDG approx between head of the bearing pointer and head of the CDI
- Use pencil method to update the HDG enroute
Passing Through a VOR/DME Intersection Procedure
Enroute
- Establish aircraft on course to the intersection using the primary NAVAID.
- Track the primary course until the indicated DME reached the published fix DME.
- Note time, if required for reporting purposes.
- Continue tracking outbound from the fix on the same course used inbound.
Turning onto a New Course at a VOR/DME Intersection Procedure
Enroute
- Establish aircraft on course to the intersection using the primary NAVAID.
- Track the primary course until the indicated DME reached the published fix DME.
- Tune in the secondary NAVAID used for the next route section
- Set the new course into the CDI
- Maintain a wind corrected heading for the primary course until starting a turn onto the new course (Use lead DME calculation to lead the turn)
- Note the time when the aircraft is wings level and on course or when the correct intercept has been established
