Systems (Book 2)

Question 1

DMC

Define

Answer 1

Display and Mission Computer

Question 2

SMP

Define and explain

Answer 2

• Stores Management Processor
• Informs DMC’s of current stores inventory & status

Question 3

DMC modes

Answer 3

• Primary: PDMC is avionics bus controller, drives the HUD & both DEPs (SDMC act as a remote terminal on the bus)
• Secondary: SDMC has failed (PDMC sweet)
• Reversionary: PDMC has failed, SDMC has taken over as Avionics bus controller

Question 4

What datalink channel will be set after a PDMC reset

Answer 4

102

Question 5

Which DMC’s manage which MFD’s

Answer 5

• PDMC manages front cockpit
• SDMC manages rear cockpit

If a DMC fails, the other will manage all six

Question 6

When is MENU2 boxed amber

Answer 6

When the MDLRS has 20min recording time left

Question 7

Which systems are powered when PROBES switch is on

Answer 7

• AoA probe heaters
• Pitot/static heaters
• Smart probe heaters

If weight-off-wheels:
- TOAT probe as well

115VAC

Question 8

What does a VV with a vertical fin, fixed on the LFD indicate

Answer 8

Drive data to aircraft symbol invalid

Pitch ladder still valid

Question 9

At what altitude will “STD” be displayed in the HUD millibar display

Answer 9

> 28,800’

1013.25 used above this even if 1013 is set

Question 10

MFD stuck key indication

Answer 10

If stuck for >10sec, the MFD indicates FAIL on the Status page. Only the stuck key is inoperative though

Question 11

MDLRS

Define

Answer 11

Mission Data Loading & Recording System

Comprised of DTC and MDLRU

Question 12

MDLRS Record time capacity

Answer 12

180mins

Question 13

CSMU

Define

Answer 13

• Crash Survivable Memory Unit
• Contains FDR and CAR

FDR: 10hrs, CAR: 1hr

Question 14

What flight/config conditions are required to enable autopilot engagement

Answer 14

• LG selected up
• Speed 200-500KCAS/0.85M
• Altitude between 1,000’ and 48,000’
• Pitch <35deg
• Roll <70deg
• Vertical speed <18,000fpm
• No autopilot failure

Question 15

When will autopilot automatically disengage

Answer 15

• A/P failure
• If in ALT hold, deviation >+-200’
• Roll angle >70deg

Question 16

How to electrically isolate the autopilot

Answer 16

Raise the standby trim cover

Only works inflight (isolation inhibited on the ground)

Question 17

General input limitations when Autopilot engaged

Answer 17

• Must be trimmed before engagement
• Stick/rudder inputs prohibited (unless SFCO is necessary)
• Pitch trim inputs not permitted
• Combat flap is the only flap setting allowed

Question 18

Default radio/antenna allocation

Answer 18

• COM1: upper
• COM2: lower

Question 19

How long will ident squawk after pushing ID

Answer 19

Approx 30sec

Question 20

TCAS assumed pilot response delay time

Answer 20

• Initial instruction : 5sec
• Change to a previous instruction: 2.5sec

Question 21

TCAS display inner ring size

Answer 21

2nm radius (regardless of scale)

Hidden on 40nm scale

Question 22

TCAS RA inhibit time post GPWS warning

Answer 22

10sec

Question 23

TCAS vertical scan extent

Answer 23

+/- 12,700’ from ownship alt

Question 24

When is TCAS forced into TA mode

Answer 24

• Alt <1,000’AMSL
• Greater than +-45deg AoB for 0.5sec
• Greater than +-60deg pitch for 0.5sec
• During/10sec after a GPWS activation

Question 25

Manouvering TCAS fail triggers

Answer 25

• Altitude change of >325’ in 5sec
• Abrupt climb/descent >11,700fpm

Question 26

Limitation on TCAS use with pylon mounted stores

Answer 26

TA mode only

Due unachievable RoC above 22,000’

Question 27

Parameters for disregarded TCAS contacts

Answer 27

• <10,000’AGL: closure above 500kts disregarded
• > 10,000’AGL: above 1,200kts disregarded
• Contacts <200’AGL
• Mode C aircraft at low level
• Contacts with RoC greater than 10,000fpm

Answer 28

2m omnidirectional

Except RADALT: 30deg downwards, all round

Question 29

Caution regarding MASS and AIM9L seeker head

Answer 29

Risk of damage to the seeker head if MASS is set to SAFE inflight
