anyway, i think your code doesn't work.. because you need to get vehicle model(GetVehicleModel(vehicleid)) not the vehicle id..

pawn Код:

if(gClass[playerid] == CLASS_PILOT)
    if(oldstate == PLAYER_STATE_ONFOOT && newstate == PLAYER_STATE_DRIVER)
    {
    new veh, Float:x,Float:y,Float:z;
    veh = GetPlayerVehicleID(playerid);
    if(veh > 425 || 447 || 464 || 476 || 520)
    GetPlayerPos(playerid, x,y,z);
    SetPlayerPos(playerid, x,y,z+1);
    }else return SendClientMessage(playerid, red, "[ERROR]: You need to be a pilot to fly this vehicle");
    return 1;
    }
}

if your code is bugged then try This..
