To indicate the probable accuracy of a position or bearing, an accuracy suffix may be added. These

Within a 2-mile radius — XRAY
Within a 10-mile radius — YANKEE
Outside a 10-mile radius — ZULU
From NAVSTAR GPS unit — GOLF PAPA
NOTE
There is no appreciable error unless otherwise stated.
b. ESM bearings:
Within 2° — ALFA
Within 5° — BRAVO
Within 10° — CHARLIE

NOTE
(1) Bearing accuracies are CHARLIE, unless otherwise stated.
(2) The word “CLASS” is inserted before A, B, C, and D.
2108 ALTITUDE OR DEPTH
When reporting positions, it may be appropriate to include an altitude or depth report.
a. Altitude. If an accurate altitude of any air track cannot be determined, estimated altitude is to be
reported using the appropriate APP 7/MPP 7 brevity code words (i.e., VERY LOW, LOW, MEDIUM,
