Instrument Approach and Landing
Holding / Loiter
Holding patterns or loitering flight may be flown at most altitudes at 280 knots, using approximately 30° of bank.
Instrument Descent
This figure represents typical penetration pattern.
💡 Do not reduce thrust below 80% rpm (85% single engine) to ensure adequate windshield defogging/rain removal/engine anti-ice effectiveness. If the throttle is retarded to idle in heavy precipitation a lower than normal idle rpm indication may be noted.
💡 The pressure altimeter should be crossed checked with the radar altimeter to confirm terrain clearance at low altitude.
Precision Approach
This figure represents typical penetration pattern.
- Descend to GCA pick-up altitude and transition to landing configuration approximately 10 miles out on final or base leg (as appropriate).
- Maintain minimum on-speed angle of attack.
When directed to commence descent:
- Retard power to approximately 82-84% rpm.
- Adjust power and pitch as necessary to maintain desired rate of descent.
A straight-in TACAN penetration followed by a GCA or ILS final requires approximately 500-800 pounds of fuel. A missed approach followed by a second GCA requires an additional 1000 pounds of fuel.
Circling Approach
Recommended airspeed from TACAN final approach fix for a circling TACAN approach, is 180 knots with gear and flaps extended.
Missed Approach
- Throttles - MILITARY
- Gear - UP
- Slats flaps - NORM (minimum of 180 knots)
- Power as required to maintain 240-250 knots and maintain a 1500 to 2500 feet per minute climb.
- Follow published missed approach procedures.
