The A-4's ailerons are tremendously effective. At 350 knots, the real aircraft has been measured to roll at 400° per second, which is matched rather closely by FlightGear. This can be loads of fun, but it also makes "rolling into" a tight turn rather touchy. Be prepared to use some reverse aileron to halt your roll at your desired bank angle or else you may well overshoot. | The A-4's ailerons are tremendously effective.

While the A-4 is an attack jet, and therefore much zippier than a 747 or Cessna | While the A-4 is an attack jet, and therefore much zippier than a [[Boeing 747|747]] or [[Cessna 172P]], its thrust to weight ratio is not in the "why bother with wings" class such as modern fighters like the Su-27 or Rafale. You cannot simply point the Skyhawk's nose to the sky and expect it to climb, nor can you escape from piloting errors simply by applying throttle. It is a pilot's aircraft, and needs to be flown within its capabilities. | ||

There are two angle of attack indicators in the cockpit. The first is a rotary dial at the top of your panel, which indicates angle of attack in "units". These are not degrees, but simply arbitrary numbers specific to an aircraft model. There is a small tick mark at the 3 o'clock position that indicates the ideal approach AoA. Final approaches under all conditions should be flown at this AoA. | There are two angle of attack indicators in the cockpit.

To aid in comprehension during approach, there is also an AoA "indexer" at eye level attached to the windscreen.

# Plan on arriving over the airfield at 1000-2000 feet AGL and 350 knots. At cruise speeds, the A-4 is a very slippery aircraft and takes a long time to slow down, so be prepared. | # Plan on arriving over the airfield at 1000-2000 feet AGL and 350 knots.

# Overfly the desired runway while descending to 1000 feet AGL. Note the runway heading on your gyrocompass. The A-4 has poor rearward visibility; you will not be able to see the runway for reference during significant portions of the landing pattern, and knowing you are on the correct heading is important. | # Overfly the desired runway while descending to 1000 feet AGL.

Alternatively, if you have a long runway, leave the nose wheel in the air and slowly apply back stick until it settles down on its own at 80-100 knots before braking. This minimizes use of the brakes by allowing aerodynamic drag to slow the aircraft as much as possible, and works well also. I don't know what standard Navy procedure was for the landing rollout. | Alternatively, if you have a long runway, leave the nose wheel in the air and slowly apply back stick until it settles down on its own at 80-100 knots before braking.
