Introduction to Radio Instruments
NOTE: If a crosswind makes the DME difficult to maintain,
increase or decrease the number of degrees you let the head of
the pointer move ahead or behind the wingtip position.
C.
Arcing - angle-of-bank method
NOTE: The angle-of-bank method is usually used when the aircraft
is within 12 DME of the station. Although each method has been
identified according to DME limits, you can use either anytime.
1.
Tune and identify station
2.
Determine direction to turn
3.
Determine desired lead point (refer to Lead Point Calculation)
4.
Initiate turn when DME equals radius of arc plus or minus
desired lead
5.
Established on the arc, adjust angle of bank (AOB) to maintain
proper distance and keep the No. 2 pointer on HSI 90-degree
benchmark (wingtip)
NOTE: Adjustments to the position of the head of the bearing
pointer will have to be made relative to the 90-degree
benchmark to compensate for the position of the wind relative to
the position of the aircraft on the arc.
