DME Slant Range Error | Does it Matter? | IFR Training

Would the vor depicted in 00:30 have reverse sensing? Shouldn’t the pilot be heading TO vor?

AIM 5−3−8. Holding specifically addresses slant range when using a suitable RNAV system (viz, GPS): Use of RNAV Distance in lieu of DME Distance. Substitution of RNAV computed distance to or from a NAVAID in place of DME distance is permitted when holding. However, the actual holding location and pattern flown will be further from the NAVAID than designed due to the lack of slant range in the position solution (see FIG 5−3−7). This may result in a slight difference between RNAV distance readout in reference to the NAVAID and the DME readout, especially at higher altitudes. When used solely for DME substitution, the difference between RNAV distance to/from a fix and DME slant range distance can be considered negligible and no pilot action is required.

Lol just happened to be looking this up the same time you posted it

Dan, after you finish the lesson the video continues for minutes on a silent black screen. lol

[@MateuszPerlak]

I think that is Slant Time Error :-)

Can't monetize it under 10 minutes

[@DNModels]

If you look at it from percentage-point-of-view, it quickly becomes obvious that it is irrelevant.
