Max drift calculation

[BEagle]

Pre-flight - Dalton or its electronic sibling.

In-flight - MDR. Never a whizz-wheel!

In flight diversion:

Draw line from nearby landmark to diversion aerodrome using chinagraph and edge of checklist.

Measure distance using miles scale on back of checklist (which ours have as I designed them that way!) - write on laminated back of checklist.

Use checklist like parallel rule to nearest VOR rose - draw line through rose and read off track.

You now have track and distance.

Apply MDR wind to establish heading and groundspeed - you should have worked out max drift prior to flight and drawn a wind arrow on your chart.

My checklists have nice clear laminated backs upon which to scribble your sums. But don't forget to lkout!

Set off when ready; fly heading and time backed up by visual confirmation.

I agree that high speed low level techniques are not relevant to low speed medium level navigation.

In the Vulcan one had a navigator to work such things out. Two actually...
