(3) (4) (5) (6) Open LRRA-1 and LRRA-2 system circuit breakers to simulate a radio altitude above 2500 feet, on LRRA-1 and LRRA-2 respectively.Ensure that present position latitude and longitude coordinates are entered into each INS (Refer to 34-41). Verify that the mode selector switch, on each INS MSU, is set to ALIGN.Ensure that gross weight of airplane is entered into the PMS.Select CRZ limit mode on the PMS limit select panel (LSP). Verify that the PMS limit indicator (LI) displays CRZ and some value of EPR limit (no dashes or blank display) indicating a valid EPR limit condition.
(7) Verify that the Captain's and F/O's FLT DIR CMPTR select switches are set to 'A'.
(8) Place the following switches on the A/P-F/D MSP to the positions shown:
Captain's and F/O's FLT DIR switches to ON.
TURB/SPEED switch to PMS
Auto throttle (A/T) Engage switch to ON.
(9) Place the Captain's and F/O's VOR-ILS/INS switches (on the P10 panel) to the INS position.
(10)
Push-in the command set knob on EPR indicator(s), to engage automatic command mode.
(11)
Position all engine throttle levers to the forward limit.
(12)
Press the PMS CDU STS/TEST key. Press the CDU line select 1 key, verify the key illuminates.
(13)
Press and hold the PMS CDU STS/TEST key and verify the following:
(a)
VERT ALERT (amber) annunciator on the pilot's panels illuminate.
(b)
PMS (amber) annunciator on the pilot's center instrument panel illuminates.
(c)
A/T (amber) annunciator illuminates (steady), on each FMA.
(d)
On airplanes incorporating SB 34-2193, PATH ARM (amber), PATH (green), SPD ARM (amber), SPEED (green) and T/HOLD (green) annunciators illuminate, on each PMS mode annunciator module (P72 panel).
(e)
On each EPR indicator; the EPR command index and EPR command counter, display an EPR command of 1.20 EPR.
(f)
Flight director (FD) pitch command bar on each ADI indicates a pitch down condition. (Pitch command bar below airplane symbol).
(g)
On airplanes incorporating SB 34-2193, glide slope pointer on each HSI indicates a vertical deviation of one dot (DOWN).
(h)
All throttle levers retard (in aft direction) at a rate of approximately 1.8./second.
(14)
Release the CDU STS/TEST key.
(15)
Verify that the glide slope pointer on each HSI is biased out of view.
