helicoper specific
GPS instrument approach in a metropolitan area
- 70 knots or less: helicopter approach and departure procedures and missed approaches use a 20:1 obstacle clearance surface
- Category A procedures: 90 kts or less
4800, 4722
initial pitch attitude corrections
to maintain altitude
should not exceed one bar high or low.
If further change is required, an additional correction of one-half bar will normally correct any deviation from the desired altitude.
- one and one-half bars is normally the maximum.
4841
pitch attitude on takeoff
1 to 2 bars
4846
AAAV for pitch
Pitch attitude should be corrected by reference to the
- altimeter
- airspeed indicator
- attitude indicator
- VSI
4873.2
"cleared to cruise"
- authorizes pilot to commence the approach
- once the pilot starts descent and verbally reports leaving an altitude in the block, they may not return to that altitude without additional ATC clearance.

Operation below DA/DH or MDA
where a DA/DH or MDA is applicable, no pilot may operate an aircraft below the authorized MDA or continue an approach below the authorized DA/DH unless—
(1) The aircraft is continuously in a position from which a descent to a landing on the intended runway can be made at a normal rate of descent using normal maneuvers
(2) flight visibility is not less than the visibility prescribed in the standard instrument approach being used
(3) at least one of the following visual references for the intended runway is distinctly visible and identifiable to the pilot...
