QDM vs QDR
 

Always get these 2 mixed up! which is which again, and any good ways to remember.

Got a sim check coming up soon.

For QDM and QDR I go alphabetical, so they end up:

QDM
QDR


QDM is the starting point, aircraft to the station and magnetic.
QDR is the station to the aircraft and magentic.

I visualize:

QDM -------->
QDR <-------



Are you set on QTE, QUJ?

I initially tried to remember the difference by saying that the aircraft flies a magnetic heading so qdM is Magnetic to the station. This didn't always work cause I found it to easy to think magnetic from the station. Now I remember the R for radial, which is radiating out from the centre, i.e. from the station. So far so good.

This sounds ridiculous written down but:

QDM - M Makes you go home/Mothers you...ie towards the station (and M for magnetic too)

QDR - R Rejects you...pushes you away..ie away from the station.

Not the slickest answer you'll see on here but I had to work it out myself..and I aint that slick.:ok:

Alternatively, forget all this 'Q' code stuff, and simply request a 'Steer'. ;)

What's wrong with 'bearing to...' & 'bearing from....'???

Dont laugh it works!
 

I like to think of a "true" cute atc lady "a cutey" sounds like QTE

Grouped with QDR, R for radio station amg from.

QUJ the completly useless one that no one seems to know what its used for!

QDM- M for magnetic. Strange but true I never get confused.
