Stephen D. Hammack Primus Apex Apex Vertical Navigation (VNAV) Software v7.2
IMPORTANT NOTES This document should only be consulted after Apex Build 7.2 is installed Pilots should consult their aircraft flight manual or pilot s guide for OEM specific VNAV functionality Display indications may vary between aircraft Customer Flight Operations Support 59
VNAV (Vertical Navigation) The VNAV function gathers information from FMS flight planning, FMS Performance, the flight director, the guidance panel, ADAHRS, and GPS to calculate, display, and provide vertical guidance to a profile or path The FMS will control the aircraft to follow an altitude profile based on the altitude constraints defined in the flight plan which can come from the Navigation Database or may be entered by the flight crew The FMS relies on the existing flight director vertical modes and control laws (SPD, ASEL, ALT, VS ) to guide the aircraft in the vertical axis It can be used for all phases of flight (climb, cruise, descent, approach, and missed approach) Customer Flight Operations Support 60
VNAV Modes
VNAV Modes There is one VNAV button on the GP but five VNAV sub modes: 1. VSPD VNAV Speed Hold 2. VSEL VNAV Altitude Select 3. VALT VNAV Altitude Hold 4. VPTH VNAV Path 5. VGP VNAV Glide Path The V preceding these modes is intended to remind the pilot that the Flight Director is synced with the FMS flight plan Customer Flight Operations Support 62
VNAV Modes - VSPD VSPD (VNAV Speed Hold) The FMS controls the flight director to climb or descend at a pilot entered speed target while meeting altitude constraints and complying with the altitude pre-selector VSPD is called a Speed-On-Elevator mode The flight director will command to pitch the nose of the aircraft to maintain the speed target Pressing SPD sets the current speed as the target and it can be adjusted by using the NOSE UP/DN buttons Customer Flight Operations Support 63
VNAV Modes - VSEL VSEL (VNAV Altitude Select) Whenever the aircraft is changing altitude towards the FMS Altitude Target, the VSEL mode will be armed At a point where the altitude can be captured, the flight director will make VSEL the active vertical mode and pitch the aircraft over from climb or descent into level l flight Customer Flight Operations Support 64
VNAV Modes - VALT VALT (VNAV Altitude Hold) When the flight director has leveled the aircraft out at the FMS altitude li target, the VALT mode will become the active mode The FMS will transition from VALT to VSPD automatically when the position of the altitude pre-selector supports the altitude change and the FMS sequences a constrained lateral waypoint Customer Flight Operations Support 65
VNAV Modes - VPTH VPTH (VNAV Path Descent) The VPTH mode is a descent mode used by the FMS to guide the aircraft along a georeferenced path When VPTH mode is active, the FMS provides a vertical speed command to the flight director. The flight director will follow the vertical speed command using VS (Vertical Speed) control laws Customer Flight Operations Support 66
VNAV Modes - VGP VGP (VNAV Glide Path) VGP mode is a vertical mode that provides approach guidance based on: FMS barometric VNAV information GPS VNAV information (for SBAS/LPV approaches) Customer Flight Operations Support 67
General VNAV Rules
Climbs are flown using VSPD only General VNAV Rules Descents are flown using VPTH or VSPD Path guidance is always followed during VPTH descents unless the FMS transitions to speed reversion (VSPD) VNAV keeps the aircraft as high as possible for as long as possible VPTH angles are from 1 to 6 (default is 3º) FMS speed target management is provided manually by the pilot Thrust control is provided manually by the pilot Customer Flight Operations Support 69
General VNAV Rules FMS must be the selected NAV source and LNAV must be engaged for VPTH or VGP to be available. All other modes can be engaged without LNAV. VNAV does not function until all PERF INIT information has been programmed and a valid aircraft performance database is installed VNAV never passes through the altitude preselect Except in VGP mode so the Missed Approach Altitude can be set The pilot should set the altitude preselect to ATC cleared altitudes If the alt preselect is set above or below current altitude and VNAV is engaged, FMS commands the autopilot to begin climb (VSPD) or descent (VSPD or VPTH) Customer Flight Operations Support 70
General VNAV Rules For VNAV to engage a minimum amount of data must be available including: ADC Cand AHARS valid Valid Altitude Pre-Selector input (not blank or dashes) Present Position valid (not in dead reckoning mode (DR)) A closed flight plan (at least origin and destination) Performance data is initialized Fuel, Initial Cruise Altitude, passengers, cargo, etc Providing wind data improves the accuracy of predictions Selecting the VNAV button without the altitude selector being initialized or the performance initialization will result in the PERF-VNAV UNAVAILABLE message being displayed VNAV will climb or descend in a PPOS hold allowing you to gain or lose altitude at your current position if necessary Customer Flight Operations Support 71

Vertical Flight Mode Display There can be one ARMED and one ACTIVE lateral mode There can be two ARMED and one ACTIVE vertical modes Customer Flight Operations Support 77
Vertical Track Alert (VTA) The Vertical Track Alert (VTA) warns the pilot of an impending vertical-mode or vertical-track change by VNAV Conditions causing a VTA include: Before TOD while in VALT Before resumption of climb after a constraint Prior to resuming descent after level-off at the speed/altitude limit Before TOD or resumption of climb while in a holding pattern Before crossing a climb/descent constraint that does not equal the altitude pre-selector Customer Flight Operations Support 78
Pre-Approach Pointer The pre-approach pointer is displayed on the left side of the vertical deviation scale 60 seconds prior to the top of descent Indicates deviations from an FMS vertical path to a descent constraint waypoint White if VNAV not installed/active, or until valid deviation CYAN (armed) in VALT mode Magenta (coupled) in VPATH mode Customer Flight Operations Support 79

Cross Dialog Box Cross Dialog Box The Cross Dialog Box enables the pilot to apply, ppy, modify, or remove conditions and constraints affecting waypoints contained in the waypoint list Checking the Vertical Dir To checkbox indicates to the FMS a vertical direct-to t is performed to the indicated altitude. A vertical direct-to cannot be performed to predicted altitudes Manually entered angle constraints, can be entered to reduce or increase the required rate of descent Customer Flight Operations Support 83
FMS Messages Customer Flight Operations Support 84
VNAV Profiles
VSPD Mode VSPD is used during all climbs and (unless a path is defined) during descents When in other modes of VNAV, a transition to VSPD is made by setting the altitude preselect to other than current altitude and pushing the SPD button on the Flight Guidance Panel 86 Use or Disclosure of information contained on this page is subject to restrictions on Page 2.
VSEL and VALT Whenever the aircraft is capturing the altitude target, the VSEL mode is armed The altitude target may be an altitude constraint or the altitude set by the altitude selector on the GP, whichever is limiting When the altitude target has been captured, the FD mode will transition from VSEL to VALT Pressing the ALT button will also force VALT mode If VNAV is disengaged while in VALT mode, the FD mode becomes ALT mode 87 Use or Disclosure of information contained on this page is subject to restrictions on Page 2.

VNAV Vertical Path (VPTH) In the VPTH mode the aircraft is controlled along a geometric path downward to a waypoint altitude constraint The path angle may be either an FMS computed value, procedure specified or pilot entered If VNAV is active and the altitude preselect is set to a lower altitude, the autopilot will automatically capture the path and the aircraft will descend Customer Flight Operations Support 90
VNAV Vertical Path (VPTH) The aircraft will automatically level off at the altitude preselect value and return to VALT mode Path descents are identical to ILS providing a constant angle descent During VPTH operations the aircraft speed is allowed to increase/decrease to maintain the path Customer Flight Operations Support VNAV does provide speed protection and will pitch the nose in a MxSpd condition and then reacquire VPTH 91
VNAV Path (VPTH) Descent Profile VALT TOD 1. Prior to TOD, PSA set, aircraft captures vertical path 2. Aircraft levels off at FMS altitude 3. New TOD is calculated by FMS, VTA displayed, transition to VPTH 4. Transition to approach mode (VGP) PSA VALT VTA TOD FAF 1 2 3 4 Destination Customer Flight Operations Support 92

VNAV Transition to Pitch (PIT) The following events result in loss of VNAV and an automatic transition from the active VNAV FD mode to the default vertical FD mode of PIT: BOD waypoint or altitude is manually deleted on the flight plan LNAV is disengaged while in VPATH mode LNAV sequences the final defined leg of the flight plan Customer Flight Operations Support 98
VGP Mode
General VGP Rules Approaches to DA minimums (SBAS/LPV, LNAV/VNAV) are flown using VGP mode Approaches to MDA minimums (VOR, NDB, LNAV, etc) should be flown using VPTH or VSPD (not VGP) The altitude pre-select should be set to the MDA so the aircraft levels off To use VNAV or the VSD display Q NH must be used below the transition altitude Q FE is altimeter adjusted to display height above ground level Q NH is altimeter adjusted to display height above sea level Customer Flight Operations Support 100
General VGP Rules DR The navigation mode cannot be Degrade (DGRD) or Dead Reckoning (DR) DGRD Customer Flight Operations Support 101
Vertical Glide Path (VGP) VGP allows the crew to manage the altitude preselect during FMSmanaged, nonprecision approaches so the approach is similar to a precision approach VGP is annunciated on the PFD Once VGP is active, the altitude preselect can be reset to the missed approach altitude Customer Flight Operations Support 102
Vertical Glide Path (VGP) The VGP sub-mode provides approach guidance based on FMS baro VNAV information as well as GPS VNAV information for LPV approaches When an FMS-managed approach is activated (LNAV/VNAV), the vertical deviation pointer is labeled VNAV When an SBAS/LPV approach is activated, the vertical deviation pointer is labeled LPV The goal during the descent is to keep the indicator centered (similar to a glideslope indicator) BAROMETRIC DATA GPS DATA 103 Use or Disclosure of information contained on this page is subject to restrictions on Page 2.
Vertical Glide Path (VGP) Once VGP is active (as shown here), the altitude preselect can be reset to the missed approach altitude The aircraft will fly a path from the FAF altitude to 50 feet above the TDZE Note: The aircraft will NOT level off at 50 but will continue to the ground if the autopilot were to remain engaged (which is not authorized) ) Customer Flight Operations Support 104
Vertical Glide Path (VGP) VGP is armed (shown in white above the ADI) when the APR button is pushed on guidance panel AND FMS is selected NAV source Non localizer-based approach is activated Aircraft is in terminal area (<30nm from destination) Approach contains missed approach point angle/altitude Nav database specified angle and altitude at MAP have not been changed by the pilot FMS VNAV arm criteria has been satisfied (FMS performance data entered in FMW) DR and DGRD are not displayed d Customer Flight Operations Support 105
Vertical Glide Path (VGP) VGP mode is engaged or active (shown in green above the ADI) when: LNAV is captured (NAV is shown as lateral FD mode) Active waypoint is final approach fix (FAF) or MAP or the flight plan distance to the FAF is <5nm Aircraft is within 75 feet of VGP path or existing path-capture logic to VGP path is satisfied Customer Flight Operations Support 106
