Day 6

Question 1

Ground control approach

Answer 1

A radar approach system operated from the ground, may be conducted with surveillance radar only or with both surveillance and precision approach radar

Surveillance radar provides 360* coverage out 60 NM

Precision approach radar antenna detects and displays azimuth, elevation, and range about aircraft on final approach

Ground Controlled Approaches CAN be executed away from established airfields (mobile radar vehicles - Tactical GCA)

Question 2

GCA availability

Answer 2

3 ways to determine if destination aerodrome has GCAs:

1) IFR supplement
2) Index of Instrument Procedures in the TLA, or index of terminal charts in the TPP
3) May be noted in the communications section of the approach plate (least desired way, not all “PAR”s are shown this way)

Landing minimums for these GCAs are found in RADAR MINIMA section of the TPP/TLA

PAR’s (and ILS) descend to a Decision Altitude (DA)

ASR’s, PAR’s w/o Glideslope, Circling Approaches use a Minimum Descent Altitude (MDA)

Circling MDA and Weather Minima to be used are those for the RWY to which THE FINAL APPROACH IS FLOWN, not the Landing Runway

Pay attention to the notes/subtext

MDA means minimum altitude you cannot cross until missed approach point where you can then either descend to land or execute the Missed Approach

Question 3

PAR

Answer 3

PAR - Precision Approach Radar Approach classified as a precision approach utilizing surveillance radar from initial Ipick-up to just prior of the final approach course. Has DA and a glideslope (Radar PLUS altitude guidance). NOT DEPICTED GRAPHICALLY

Whatbis provided with a PAR?

• Azimuth
• Glideslope
• Range

Pilot’s report of “runway in sight” or “visual” is NOT A REQUEST to proceed visually

ATC will discontinue PAR when

• requested by pilot
• anytime the approach to landing threshold is questionable
• aircraft passes the landing threshold
• the pilot reports the runway/approach lights in sight and request to or advises the he/she will proceed visually

Question 4

GCA emergency

Answer 4

No-Gyro approach

• used when A/C nav display, RMI, or HSI is inoperative
• pilot is instructed “turn left, stop turn, turn right, stop turn” as necessary
• use half standard rate turns on final when instructed

LOST COMMO (FIH section A-6,7)

• while being vectored to final approach course, you must hear controller at least once per minute
• you must hear from the ASR final controller once every 15 seconds
• must hear from PAR final controller oncer every 5 seconds

When PAR safety limits are exceeded, or radical deviation is observed, pilot will be advised to execute a go-around

Radar Monitoring automatically provided when:

• weather is less than 1000’ - 3
• when requested by pilot
• at night (N/A at US Army Airfields)
