V+ Design - Audible Warnings

feature author: Paul Halliday


The V+ worksheet for Audible Warnings is a big one with many models in it. The total worksheet is too big to display in one figure and is divided into three figures. Figure 36 contains models for the Ground Proximity Warning System (GPWS). Figure 37 contains more GPWS models. Figure 38 contains miscellaneous models for the following.

  • Traffic Collision Avoidance System (TCAS) voice messages

  • Altitude alert warning

  • Decision height warning

  • Overspeed warning

  • Stall warning

  • Landing gear warning

  • EFIS auxiliary warning

  • Standby ADI auxiliary warning

Each of the models, except as noted below, has an input from the host and either a One-Shot FXDirect Player or Looped FXDirect Player object. Most of the players are looped because the warning message continues until the host trigger turns it off.

There are two slightly more complicated models: GPWS TERRAIN PULLUP and GPWS NORMAL SELF TEST. These voice messages are composed of two different WAVE files. The One-Shot object plays the first part of the message, and the Looped object plays and repeats the second part of the voice message after a delay, specified by the On Delay object.
