What is a standard climb?
Standard IFR climb gradient is 200 feet per nautical mile.
What are the standard holding speeds?
0-6000 Feet: 200 KIAS
6001-14000 Feet: 230 KIAS
Above 14001 Feet: 265 KIAS
What is the difference between flyby and flyover waypoints?
Fly-by waypoints: Fly-by waypoints are used when an aircraft should begin a turn to the next course prior to reaching the waypoint separating the two route segments. This is known as turn anticipation.
Fly-over waypoints: Fly-over waypoints are used when the aircraft must fly over the point prior to starting a turn.
Fly Over is Circled on the chart
What is the reciprocal of 266?
86
Dumping fuel at 1500pounds/hour, how long to dump 16500 pounds?
11 Hours
How long to travel 90nm, with 190TAS and 60kts headwind?
solve as a proportion. 190-60= 130 knots groundspeed 130kts/60min = 90nm/X 90 x 60 divided by 130 = X 41.5 min
When should you start down from FL350 to cross fix at 12,000ft
3:1 Rule
69 Miles
No published hold on the missed, what entry, speed, leg length would you use?
Right turns.
0 to 6000’ 200knots, 6-14000 230 knots, above 14k 265 knots.
Below 14000’ 1 min, above 14k; 1.5 min legs.
What is an MSA?
The Minimum Sector Altitude (MSA) is the lowest altitude which may be used which will provide a minimum clearance of 300 m (1 000 ft) above all objects located in the area contained within a sector of a circle of 46 km (25 NM) radius centered on a radio aid to navigation.
What is an MEA?
The minimum en-route altitude (MEA) is the altitude for an en-route segment that provides adequate reception of relevant navigation facilities and ATS communications, complies with the airspace structure and provides the required obstacle clearance.
Put simply, the MEA is the lowest altitude to be flown in an airspace structure which assures:
- Reception of navigation aids necessary to navigate accurately along the required route.
- Two-way communication with air traffic control.
- Safe clearance from obstacles within the sector.
- conformity with any air traffic control procedures applicable within the sector.
**Provides 1000’ of obstacle clearance within 4 NM either side of the airway centerline in non mountainous areas
***Provides 2000’ of obstacle clearance within 4 NM either side of the airway centerline in mountainous areas
What is a MOCA?
Minimum Obstacle Clearance Altitude
The lowest published altitude in effect between radio fixes on VOR airways, off airway routes, or route segments that meet obstacle clearance requirements for the entire route segment. This altitude assures acceptable navigation signal coverage within 22 NM of a VOR.
What is a TAA?
Terminal Arrival Altitude is the lowest altitude that will provide a minimum clearance of 300 m (1 000 ft) above all objects located in an arc of a circle defined by a 46 km (25 NM) radius centred on the initial approach fix (IAF), or where there is no IAF on the intermediate approach fix (IF), delimited by straight lines joining the extremity of the arc to the IF. The combined TAAs associated with an approach procedure shall account for an area of 360 degrees around the IF.
From approach plate, what is the number inside the “()” brackets beside DA.
DH: Decision Height
This is measured in AGL while a DA (Decision Altitude) is measured in MSL.
Define MEA and a MOCA?
MEA provides 2 way ATC communication and NavAid coverage within the entire route section. It also provides obstacle clearance (1000’ non mountainous/2000’ mountainous). MEA is the first number shown on the airway.
MOCA
Provides obstacle clearance (1000’/2000’) while only providing nav signal within 22 miles of VOR
When would you want two alternates?
Destination and first alternate marginal weather conditions. Or 3585 exemption used, two alternates needed.
- *A second alternate is required (FAR 121.619) when the weather conditions forecast for the destination and first alternate are “marginal”.
**Exemption 3585 requires the use of two alternates
Why is localizer more sensitive on a back-course? On a back course approach, why do we put in the front course
We put in the front course to account to reverse sensing. Sensitivity is greater because the localizer antenna is closer to the airplane during a back course.
What is an OROCA?
Off Route Obstruction Clearance Altitude
Provides obstruction clearance with a 1000’ buffer in non mountainous terrain and 2000’ in mountainous terrain. This altitude may not provide signal coverage from ground based navigation aid, air traffic control radar, or communications coverage.
When is an alternate required?
1, 2, 3 Rule
Within one hour before and one hour after ETA, the ceiling is below 2000 feet, and 3 statute miles.
What are the requirements for a takeoff alternate?
Aircraft having two engines: Not more than one hour from the departure airport at normal cruising speed in still air with one engine inoperative.
When would you need a takeoff alternate?
Weather below landing minimums at departure airport.
When do you have to stop at an ILS hold line?
When requested by ATC or (weather below 800’ ceiling or 2SM vis {verify answer])
What is tower’s NORDO light gun signal to be cleared to land?

What are IFR fuel requirements? (domestic operation)
Fly to the destination, then the most distant alternate and then for 45 minutes at normal cruise speed.
Explain how a pitot static system works
The pitot-static system of instruments uses the principle of air pressure gradient. It works by measuring pressures or pressure differences and using these values to assess the speed and altitude.[1] These pressures can be measured either from the static port (static pressure) or the pitot tube (pitot pressure). The static pressure is used in all measurements, while the pitot pressure is used only to determine airspeed.
What does PJE mean in the NOTAMS?
Parachute Jumping Exercises
What is a Grid MORA?
GRID MORA provides terrain and man-made structure clearance within the section outlined by latitude and longitude lines. The Grid MORA value clears all terrain and man-made structures by 1000ft in areas where the highest elevations are 5000ft MSL or lower and by 2000ft in areas where the highest elevations are 5001ft MSL or higher.
What do you need when given a vector off a SID/STAR?
- Heading
- Altitude
- Speed (if necessary)
- Expect to Resume (SID, STAR, etc.) At (NAVAID, FIX, Waypoint)
