The Map vs the KneeboardAll the information needed to fly must be on the map! You hold the map above the panel to maintain a look out while glancing at the map. This technique requires practice but is not unlike the Straight and Level lookout technique: lookout, attitude, instruments (Map). The map must be folded and maintained track orientated. Map Planning - a finished leg.A typical low level route leg is pictured opposite. Note the minute marks are .5 Nm long to assist in track corrections.
Picking FixesFrom low level, 2000ft or below, your choice of fixes should be determined by 'vertical' structures. For example, masts, mountains, rail bridges with finer accuracy points nearby - you cannot plan to fly directly over a mast or you may fly into it at low level. In this case I have picked:
The flying technique requires visual corrections to track using big geographical features on or near track, funnel features or a standard closing angle for the aircraft - Heading change = 10o held for 6 miles for every mile off track. To correct timing, increase speed by 10kts for your speed in Nm/min to compensate for 10secs. |
