Missed approach structure
Missed approach point – MAPt
- the moment at which the aircraft will reach the DA/H at the end of the descent during a precision approach (ILS, MLS, GLS, APV)
- a radio-navigation means (NDB/VOR/Marker), a specified radial-distance from a VOR/DME or a NDB/DME, or a GPS waypoint ; during non-precision approach (LOC, VOR, NDB, LNAV).
Some non-precision approaches, in particular those to be performed without DME support, include a time-based missed approach point. The pilot will start a timer when passing the final approach point. It will compare it to a provided or computed timer until the missed approach point.
The concentration of the pilots should be focused on establishing the climb and changing the aircraft configuration (landing gear, flaps).
Types of missed approaches
Straight-in missed approach
Turning missed approach
Subtype: Turning point missed approach
Initiate a turn when passing 9.0DME of MEX VOR.
Subtype: Turning altitude missed approach
Initiate a turn when passing 2000 feet.
Regulatory flight parameters
Minima vary with aircraft one-engine inoperative climb gradient.
- Visual references are not acquired at minima or passing the MAPt
- Approach is not stabilized (runway axis, descent path, speed)
- Runway is not clear of traffic or obstacles
- ATC will not issue landing clearance
- ATC will command a go-around for safety reasons
About stabilization, operators will issue mandatory or recommended stabilization heights at which an aircraft must be configured for landing, in good position with runway, at a correct airspeed. Deviation values will exist to tolerate parameter variations due to environmental factors. If one of these values is exceeded, a go-around must be initiated.
- Stabilization height: 1000ft AGL under IMC / 500ft AGL under VMC
- Runway axis: 1 dot deviation on conventional approach / 0.5 dot on GNSS approach
- Descent path: 1 dot deviation above or below
- Airspeed: not below approach speed, no more than 5 knots in excess
Initiate a go-around
- a relevant pitch value necessarily positive, near the takeoff standard setting
- a positive rate of climb.
- very low or no climb at all
- rapidly decreasing airspeed bringing the aircraft near stall.
- You will need to adjust pitch and power/thrust
- You will have to adjust your aircraft configuration
- You will need to fly the published missed approach
- You will have to communicate with ATC
Since you had configured your aircraft for landing, you will need to configure it back to takeoff/climb position. This will take more or less resources depending on your aircraft complexity:
- Retract flaps if required
- Retract landing gear if possible
- Adjust power/thrust to normal climb power/thrust.
Then, consider your flight trajectory.
