Question 2

ARO

Answer 2

Airborne RADAR Operator 5.22.2

Question 3

Answer 3

Final Approach Point located 4nm from the HEDA coordinates

5.22.2

Question 4

HEDA dimensions

Answer 4

Helicopter En Route Descent Area:
1- An area 8nm in diameter that is entirely offshore, and
2- Completely free of FIXED obstacles
5.22.2

Question 5

IF description, including altitude restrictions

Answer 5

Intermediate Fix:
A fix on the en route structure no more than 40nm from the HEDA coordinates.
No descent below 1500’ (MIA) until 20nm from HEDA
5.22.2

Question 6

When does the Intermediate Segment begin and what should be acomplished?

Answer 6

Begins within 40nm
Obtain weather if available (normally before 40nm)
Request cruise clearance 
May descend to 1500 MIA
Within 20nm descend to 900' MSL
Confirm RADALT and RADAR working

GOM 5.22.3

Question 7

When does the Final Descent begin?

Answer 7

Descent begins at 4nm at 900’ MSL

ARO confirms clear area and instructs pilot to descend
Before descent below 700’ MSL (min alt w/o RADALT) ARO confirms RADALT operational.

Question 8

Min ALT for HEDA with RADALT failed and operational

Answer 8

700’ MSL (failed) or 400’ AWL (operational)

Question 9

Min Altitude if RADAR target within 1nm of aicraft

Answer 9

900’ MSL

Question 10

Min Altitude without RADALT or RADAR or with

ANY obstruction in area (not within 1nm)

Answer 10

700’ MSL

Question 11

Min Altitude for HEDA (everything operational) and no obstacles in the HEDA area.

Answer 11

400’ AWL

Question 12

List four conditions for missed approach

Answer 12

1- Not VMC at HEDA coordinates
2- Failure of RADAR
3- Target in HEDA below 700’ MSL
4- Failure of RADALT below 700’ MSL

Question 13

Describe Missed HEDA Procedure

Answer 13

Climb on heading to 900’ MSL, then a climbing turn to 2000’ MSL to the HEDA and hold 3.0nm legs on final approach course, or as directed by ATC, remain with 10nm of HEDA coords

Question 14

Descent Below 700’ AWL is not allowed with either of the two following conditions:

Answer 14

1. Any obstructions in the HEDA

2. Radio altimeter inoperative

Question 15
