If the Mode C readout continues to be invalid:(a) Instruct the pilot to turn off the altitudereportingpart of his/her transponder and include thereason; and(b) Notify the operational supervisor-inchargeof the aircraft call sign.PHRASEOLOGY−STOP ALTITUDE SQUAWK. ALTITUDE DIFFERS BY(number of feet) FEET.e. Whenever possible, inhibit altitude readouts onall consoles when a malfunction of the groundequipment causes repeated invalid readouts.5−2−18. ALTITUDE CONFIRMATION− MODE CRequest a pilot to confirm assigned altitude on initialcontact unless:NOTE−For the purpose of this paragraph, “initial contact” meansa pilot’s first radio contact with each sector/position.a. The pilot states the assigned altitude, orb. You assign a new altitude to a climbing or adescending aircraft, orc. The Mode C readout is valid and indicates thatthe aircraft is established at the assigned altitude, ord. TERMINAL. The aircraft was transferred toyou from another sector/position within your facility(intrafacility).PHRASEOLOGY−(In level flight situations),VERIFY AT (altitude/flightlevel).(In climbing/descending situations),(if aircraft has been assigned an altitude below the lowestuseable flight level),VERIFY ASSIGNED ALTITUDE (altitude).or(If aircraft has been assigned a flight level at or above thelowest useable flight level),VERIFY ASSIGNED FLIGHT LEVEL (flight level).REFERENCE−FAAO 7110.65, Beacon Identification Methods, Para 5−3−3.5−2−19.
