AIRPORT OP NUMBERS Flashcards
ILS approaches
Service volume
___ degrees either side of the course along a radius ____from the antenna
______ degrees either side of the course along a radius of _____.
GSIA (glideslope intercept altitude) is also the point at which pilot’s operating under part 121 would determine if the approach could be continued if newly reported weather goes below minimums
Intercept should be done from below the glideslope. If intercepting the glideslope from above, there is a possibility to intercept a false 6° or 9°glideslope above the actual glideslope. The 6° glideslope might have reverse steering. Both glideslopes would have a substantially higher descent rate than the actual glideslope.

Category I, II, and III ILS minimums
Cat I: DH_____ and RVR ______ (with TZ and CL lighting, _______ RVR ft)
Cat II: DH _____ and RVR ______
A Cat II approach to a DH below 150ft requires touchdown zone lighting, runway centerline lights, and RVR
A pilot may be approved for Cat II operations after that pilot has logged more than 100 hours in the make and model airplane under part 121 and made 3 Cat III approaches in actual or simulated IFR since the beginning of the preceding sixth month
Cat IIIa: No DH or DH below _____ and RVR not less than _______
Cat IIIb: No DH or DH below ____and RVR less than __________
Cat IIIc: No____________
CAT I 200ft 2400ft 1800
CAT II 100ft 1200ft
CAT IIIa 100ft 700ft
CAT IIIb 50ft 700ft but not less than 150Ft
CAT IIIc DH and no RVR limitation

Normal aircraft: ______ AGL traffic pattern, large/turbine: _____ AGL traffic pattern
Traffic pattern altitude should be maintained until the aircraft is at least abeam the approach end of the landing runway on the downwind leg
Aircraft should not be operated in the traffic pattern at an indicated airspeed of no more than_____ kts
Aircraft should not be operated within ___ miles of the airport with an indicated speed above____ kts

For all straight-in instrument approaches, to include contact approaches in IFR weather conditions, the approach must be stabilized before descending below _______ feet above the airport or TDZE.
For visual approaches and straight-in instrument approaches in VFR weather conditions, the approach must be stabilized before descending below ______ feet above the airport elevation.
For the final segment of a circling approach maneuver, the approach must be stabilized_____ feet above the airport elevation or at the MDA, whichever is lower. These conditions must be maintained throughout the approach until touchdown for the approach to be considered a stabilized approach. This also helps you to recognize a wind shear situation should abnormal indications exist during the approach.

How far apart do runways have to be to conduct simultaneous approaches to parallel runways?
An approach system permitting simultaneous ILS/MLS approaches to parallel runway with centerlines separated by 4,300 to 9,000 feet, and equipped with final monitor controllers. Simultaneous parallel ILS. MLS approaches require radar monitoring to ensure separation between aircraft on the adjacent parallel approach course.
What is an MORA?
Minimum Off-Route Altitude derived by Jeppesen. MORA provides known obstruction clearance 10 NM either side if a route centerline including a 10 NM radius beyond the radio fix reporting or mileage break defining the route segment.
What is the frequency range for a localizer?
The localizer transmitter operates on one of 40 ILS channels within the frequency range of 108.10 to 111.95 MHz. ALWAYS END WITH ODD.
