VFR navigation
Hi all
When I did my CPL we had a formula that for every one mile we were off track we would turn left/right 30 degrees for x-amount of minute's. This was based on a TAS of 120 Knots, just wondering what is the formula to work it out for other speeds as I am flying a Grob 115 that has no GPS or DME and a VOR receiver that has a questionable accuracy! Just want to make sure that my nav is up to scratch before I make a dipstick of myself next weekend:ok: |
Nav Question....
Please borrow a gps as a back up...this is 2009, not 1959.
Just my thoughts. |
I dont see the point of this as you dont have any resource other than visually estimating how far off route are you. In that case, wouldnt turning towards your reference or making a visual correction would sufice?
Im a low tech flyer myself as I navigate with nothing but a mag compass (questinable acquracy as well) and a navigation chart. I limit myself to following things (railroads, roads, powerlines etc) no farther than 5nm depending on the situation. Works out pretty well for me. I guess I simply dont see how what you are asking for can actually become practical in real un-aided VFR navigation. |
