Figure 4.15. Point in Space Approach.
4.5.1.5. Review Missed Approach. Review the published missed approach departure
instruction to ensure you can achieve the published climb gradient. For copter only
procedures, the missed approach is based on a climb gradient of at least 304 feet per
mile; twice the angle used for fixed-wing instrument approach procedures (IAP). If a
90 knot missed approach is performed, then this climb gradient equates to a 456 foot
per minute minimum rate of climb, no wind.
4.5.1.6. RNAV Departure Procedures. Helicopter-only GPS departure procedures
are to be flown at 70 knots or less since turning areas and segment lengths are based
on this speed.
4.6. Altimeter Setting Procedures. The altitude indicated on the altimeter may be in error
if the altimeter check is conducted with the rotors turning. This error is due to the difference
in pressure caused by the rotor downwash. The difference in pressure causes the altimeter to
