Principles of traditional Instrument Procedure design<br />

3. Fly-Over Turns<br />

y<br />

The protected area around a turn is necessarily greater than the sum of the track protection required<br />

to and from a fix: it must take into account<br />

the fix tolerance<br />

the time it takes a pilot to react to crossing the fix and establish the turn<br />

the effect of worst-case worst case wind pushing the aircraft to the outside of the turn<br />

the turning radius of different aircraft types<br />
