ROL
- Route operating limitation
- Usually temporary due to hazard or restriction. Can become active or inactive.
- Found in table on chart.
- When considering altitude, first consider ROL, MSA, cruising levels, freezing levels before selecting altitude.
Onwards Clearance Time
The time an aircraft can expect to leave the holding location.
Expected Approach Time
In the event that an aircraft is instructed to hold at an initial approach fix, if the delay exceeds 5 minutes, an expected approach time will be passed.
Initial Approach
Begins at an IAF, brings aircraft from en-route to approach system, for alignment and manoeuvring.
Intermediate Approach
Begins at the intermediate fix or end of a reversal procedure, designed to configure and stabilise the aircraft for the final approach.
Vat
Indicated airspeed at the threshold.
Vyse
Best rate of climb speed with one engine inoperative (blue line)
Vxse
Best angle of climb speed with one engine inoperative.
Vmca
Minimum control speed in the air.
New Zealand FIR
Covers the countries domestic airspace.
Auckland FIR
Covers international airspace over the surrounding South Pacific, Southern Ocean, and Tasman Sea. Extends to Antarctica. NZ is responsible for oceanic flight guidance.
FIR
Flight information region
IAF
Initial approach fix
TAA
- Terminal arrival altitude
- The lowest altitude that provides at least 1,000 feet of obstacle clearance within a 25-nautical mile radius of an IAF or IF for RNAV approaches
MEA
Minimum enroute altitude
MRA
Minimum reception altitude
OCA
Obstacle clearance altitude
RVSM
Reduced Vertical Separation Minima. Reduces required vertical separation between aircraft from 2000’ to 1000’ between FL290 and FL410.
