Planning.

9.   Selection of maps.  There are various types of maps at our disposal:-

     (a)  1" to 1 statute mile.

     (b)  ¼" to 1 statute mile.

     (c)  1/500,000.

     (d)  1/1000,000.

10.  The length and type of the sortie will normally dictate the maps to be
used. For route flying the obvious choices are (b) and (c). Alternatively
if the sortie is lengthy consideration should be given to using (d) since
joining maps produces inaccuracies, and it is not convenient to have several
maps or a large intricately folded map in the cockpit.

11.  The larger scale maps, 1" to 1 statute mile for instance, because of
their detail of relief and features, should be used to select approach to and
from the target and for actual pinpointing of the target itself.

12.  Ensure the maps are folded and stowed so as to be readily at hand.
Accurate low level navigation is difficult enough and the confines of the
average fighter cockpit does not lend itself to map sorting operations.

Sequence of Flight Planning.

13.  Study the Form D carefully checking exact target location and other
details appertaining to routeing.

14.  Obtain the latest weather forecast inoluding the winds and temperatures -
for the various areas and heights.

15.  Decide the maps to be used.

16.  Decide the route to be followed bearing in mind the following:-

     (a)  Decide the direction of attack and approach to the pull up point first.

     (b)  Plan to allow for weather factors and to give the greatest
     navigational assistance. This applies particularly to the last leg
     approaching the target.

     (c)  Plan to avoid heavily defended areas. Remember the size of an airfield
     or town is often much larger than the map shows.

     (d)  Plan to cross bomblines or well defended line features as near 90
     degrees as possible, and plan to cross these areas at a different point on
     the return.

17.  Draw in the tracks and the correct turning circles for the speed and bank
to be flown.

18.  Calculate the distances round the turns, measure the remaining distances
and tracks and record on the flight plan form. Each turn should be included in
the leg following it.

                                                         /19.
