What is touchdown zone elevation?
Touchdown zone elevation is the highest point in the first 3000 feet of the landing runway.
AFMAN 11-217V1, 6.5.4.4.2
How much fuel are we required to carry for a mission?
The T-1A will normally take off with a full fuel load from the home field. The aircraft commander will decide whether to take off at the home field or out base with less than a full fuel load. Factors to consider include weight and balance, mission requirements, aircraft performance, weather conditions and fuel conservation.
When may a PIC make changes to a route or destination not shown on the original
flight plan without refiling?
The format for making changes to a flight plan is printed on the back of the DoD IFR Supplement. Before takeoff, or while airborne, changes may be made to the original filed flight plan without re-filing provided:
- ATC/Destination is aware of changes; prevent erroneous SAR or unannounced arrival.
- The change does not penetrate an ADIZ.
- The controlling ATC agency approves the change for an IFR flight.
- The change complies with applicable host-nation rules.
AFI 11-202 Vol 3, 4.17.3
Weather priorities in order?
- Locally approved mission execution forecasts.
- Local military weather unit.
- Servicing Air Force operational weather squadron (OWS).
- Another military weather unit (Air Force CWT or OWS, Navy, or Marine unit).
- FAA weather forecast or flight weather briefing agency (or equivalent overseas).
- The nearest flight service station (FSS).
AFI 11-202 Vol 3, 4.12.1
What is a diverse departure? When can we not execute a diverse departure? What climb gradient is required?
- A diverse departure allows the pilot to execute a turn in any direction from the runway and remain clear of obstacles.
- Minimum climb gradient of 200‘/NM will ensure proper obstacle clearance.
- Diverse departures are not authorized when an ODP, obstacle climb gradient, or non-standard takeoff weather minimums are published for the planned departure runway
When do we file IFR?
Fly USAF fixed-wing aircraft under IFR to the maximum extent practical.
Pilots shall fly under IFR if:
- Weather conditions do not permit VFR flight
- Airspace rules require IFR flight (e.g. Class A airspace).
- Operating in excess of 180 KTAS within (not simply crossing) federal airways.
- Operating fixed-wing aircraft at night, unless the mission cannot be flown under IFR.
AFI 11-202 Vol 3, 4.15.1
When are we not allowed to do a procedure turn?
Do not execute a procedure turn or HILO PT in the following situations. (Many people use the memory aid – SNERT).
- S- “Straight-in” approach.
- N- via No PT routing.
- E- Established in holding, cleared the approach, and the holding course and procedure turn course are the same. NOTE: This generally applies if you are already established at the minimum holding altitude. If in doubt, query
- R- Radar vectors to the final approach course.
- T- Timed approach, when established in holding and given a time to depart the FAF inbound.
What are methods we can depart IFR?
SID, ODP, Diverse Dep, ATC instructions, MAJCOM certified, Non standard takeoff minimums.
What constitutes the runway environment?
Threshold, threshold markings or threshold lights. Runway end identifier lights.
Touchdown zone, touchdown zone markings, or touchdown zone lights.
Runway or runway markings. The runway lights. Visual approach slope indicator.
AFMAN11-217V1 12.1.2.2.2 thru 12.1.2.2.7
Standard holding pattern?
The standard no-wind holding pattern is flown by following a specified holding course inbound to the holding fix, making a 180° turn to the right, flying a heading outbound to parallel the holding course, and making another 180° turn to the right to intercept and follow the holding course to the fix (Figure 8.1). The holding pattern is nonstandard when the turns are made to the left. Unless otherwise instructed by ATC, pilots are expected to hold in a standard pattern.
AFMAN11-217V1 (8.1.1)
What is considered station passage for a TACAN, VOR, NDB?
- TACAN- Station passage occurs when the range indicator stops decreasing.
- NDB- Station passage occurs when the bearing pointer passes 90° to the inbound course.
- VOR - Station passage occurs when the TO-FROM indicator makes the first positive change to FROM.
What is established on course for TACAN, LOC, NDB?
- VOR/TACAN/RNAV/GPS: half-scale deflection
- LOC: Full scale deflection/ case break
- NDB: +- 5 degrees
Range of localizer and glideslope?
LOC: 18mi
GS: 10mi
Aircraft app cat based on?
Aircraft approach category is based on 1.3 times the stalling speed in the landing configuration at maximum certificated gross landing weight.
• A - Speed less than 91 knots.
• B - Speed 91 knots or more but less than 121 knots.
• C - Speed 121 knots or more but less than 141 knots.
• D - Speed 141 knots or more but less than 166 knots.
• E - Speed 166 knots or more.
AFMAN11-217V1 6.5.1.1
May USAF fixed wing pilots accept a LAHSO clearance?
No. Pilots of USAF aircraft may passively participate in LAHSO (land or take-off when another aircraft has been given a LAHSO clearance). The PIC is the final authority whether to take-off, land or continue a touch-and-go when a merging aircraft has received a LAHSO clearance.
AFI 11-202 Vol 3, 7.9.
What would drive approach to be circling approach?
- Final approach course is aligned with the runway centerline by an angle greater than 30 degrees.
- Approach not aligned with the runway
For a low altitude IAP, the initial descent gradient can’t exceed ______’/NM?
For a low altitude IAP, the initial descent gradient will not exceed 500 ft/nm (approx 5°); 1000 ft/min for a high IAP.
AFMAN 11-217V1, 6.5.4.2.2
Mandatory calls PNF?
Mandatory Calls for Pilot Not Flying (PNF). The PNF will make the following calls:
• Nonprecision Approaches:
o One hundred feet above MDA/DA.
o 3.13.1.1.2. “Minimums” at MDA/DA.
o “Runway in sight.” Call when the runway environment is in sight. Do not call too soon when obstructions to vision, such as fog, haze, low clouds, etc., are present.
o “Go around.” Call at the MAP if the runway environment is not in sight.
• Precision Approaches:
o One hundred feet above DH/DA.
o “Continue.” Call at DH/DA if the runway environment is in sight but the runway red termination bars or the red side row bars are not visible or identifiable. When using the “continue” call at DH/DA, the “land” or “go around” calls described below may be delayed until 100 feet AGL above TDZE to line up with procedures described in AFMAN 11-217. In order to call “land” at 100 feet, the red termination bars or the red side row bars must be visible and identifiable.
o “Land.” Call at DH/DA if the runway is in sight and the aircraft is in a safe position for a normal landing.
o “Go around.” Call at DH/DA if the runway environment is not in sight or the aircraft is not in a safe position for a normal landing.
o When flying an RNAV approach to LNAV/VNAV minimums, use the precision approach calls. For all other GPS approaches, use nonprecision calls.
• Climbout:
o Transition altitude.
o At 1,000 feet below assigned altitude.
• Descent:
o Transition level.
o At 1,000 feet above assigned altitude.
o At 1,000 feet above initial approach fix altitude or holding altitude.
o At 100 feet above procedure turn, final approach fix altitude, and any step down altitude inside the final approach fix.
• Deviations. The PNF the aircraft will announce heading deviations, airspeed deviations of 5 knots or more below desired, and altitude deviations of 100 feet or more from desired.
