Question

Should an error in excess of plus or minus ________ of plus or minus ______ degrees be indicated through use of a ground check, or plus or minus ____ degrees using the airborne check while conducting VOR receiver checks, Instrument Flight Rules (IFR) flight must not be attempted without first correcting the source of the error.

A) 2; 4; 6
B) 4; 2; 8
C) 6; 8; 10
D) 8; 6; 12

Answer 1

The maximum permissible errors for VOR receiver checks under IFR are ±4° on the ground and ±6° airborne. If the error exceeds these values, the source must be corrected before IFR flight.

Step-by-step explanation:

The question asked relates to the tolerances allowed for VOR receiver checks under Instrument Flight Rules (IFR). For standard VOR receiver ground checks, the maximum permissible error is ±4°. When conducting an airborne check, the error must not exceed ±6°. These regulations ensure that the navigation equipment is functioning accurately enough for safe IFR flight operations. If errors in excess of these values are indicated, the source of the error must be corrected before IFR flight is attempted.

Thus, the correct answer is: A) 4; 6; and this can be remembered as the 4-6 rule for VOR receiver check errors.
