Avarial don't have a 50' fly. They have 15' until they reach 10th level, when they get 20. And since he spell limits you to 5 HD or less...
Perhaps you are thinking of the 3.0 version. The 3.5 version that I am using is from Races of Faerun.
[sblock]Abilities and
Racial Features
Avariels have all the elven racial traits listed in the Player’s
Handbook, except as follows:
• +4 Dexterity, –2 Constitution, +2 Intelligence, +2 Wisdom.
Avariels have hollow bones and, as a result, are more fragile
than humans. At the same time, they are gifted with a keen
intuition and intellect, and an almost otherworldly grace.
• Keen Sight (Ex): Avariels gain a +4 racial bonus on all Spot
checks; this replaces the standard +2 racial bonus that most
elves gain.
• Avariels gain a +4 racial bonus on Jump checks. They are
strong for their weight.
• Proficient with either rapier or longsword; proficient with
lasso and bolas. This replaces the standard elven weapon proficiency
with longswords or rapiers and proficiency with shortbow,
longbow, composite longbow, and composite shortbows.
• Flight (Ex): Avariels have a flying speed of 50 feet with average
maneuverability, as long as they do not carry more than a
Medium load, are not wearing Heavy armor, and are not
fatigued or exhausted. Avariel wings have a span of 12 feet on
average; they cannot fly in an area that does not allow them
to fully extend their wings.
An avariel may make a dive attack. A dive attack works just
like a charge, but the avariel must descend a minimum of 30
feet and attack with a piercing weapon; if she hits, she deals
double damage. An avariel can use the run action while flying,
provided she flies in a straight line. For more information on
flight, see the Tactical Aerial Movement section in Chapter 3
of the DUNGEON MASTER’s Guide.
• Automatic Languages: Common, Elven, home region. Bonus
Languages: by region.
• Favored Class: Cleric.
• Level Adjustment: +3. Avariels are more powerful and gain
levels more slowly than most of the other common races of
Faerûn. See Table 1 in the Introduction.[/sblock]
