INSTRUMENT FLIGHT RULES WORKBOOK

Example:

"HOUSTON CENTER, NAVY 6E432, LEAVING ONE SIX THOUSAND FOR EIGHT

THOUSAND."

Speed Adjustments

Advise ATC anytime cruising true airspeed varies plus or minus 5 percent, or 10 knots,

whichever is greater, from that given in the flight plan. When complying with speed adjustments

maintain an indicated airspeed within plus or minus 10 knots of the assigned airspeed. Holding

airspeed, enroute descent airspeed, and approach airspeed changes do not require reports.

Malfunctions

Pilots are required to report to the ATC controlling agency any in-flight malfunctions of

navigation or communication equipment, such as loss of VOR or TACAN or impairment of

communications capability. The report shall include aircraft's ID, equipment affected, the degree

to which the pilot's capability to operate IFR is impaired, and the nature and extent of assistance

desired from the controlling agency.

Weather (WX)

Pilots encountering unusual or unforecasted weather, weather on an IFR approach differing from

the latest observation, or weather below landing minimums which caused the pilot to execute a

missed approach are required to make a Pilot Weather Report or PIREP. The PIREP format is

contained in the Flight Information Handbook.
