Learn how to fly a straight-in approach: join final safely, set a three-degree descent, manage speed and traffic, and know when to go around.
To fly a straight-in approach, align with the landing runway well before final, intercept a normal glide path from below, reduce speed and configure in stages, then hold the runway aiming point steady. Check traffic, make the required calls, and go around if the approach is not stable.
In Aviation & Real-World Flying, straight-in describes the route to final, not a licence to ignore traffic, terrain, weather or published procedures. You approach on the extended runway centreline without first flying the usual downwind and base legs.
What counts as a straight-in approach?
A straight-in approach puts the aircraft on final with no substantial circling or base-to-final turn immediately before landing. It can be flown visually, under ATC vectors or as part of a published instrument procedure.
| Type | How it is flown | Main constraint |
|---|---|---|
| Visual straight-in | Align visually with the extended centreline and maintain a normal descent to the runway. Our visual-final technique guide covers sight pictures, aiming points and runway alignment. | You must retain the required visual references and avoid conflicting traffic. |
| Instrument straight-in | Follow the published final course, altitude restrictions and minima. | The chart, not an improvised three-degree calculation, controls the approach. Use our instrument-approach procedure walkthrough for the complete sequence. |
| Traffic-pattern arrival | Join downwind, base or another locally prescribed circuit entry before turning final. | This usually offers better sequencing and more time to inspect the runway and wind. |
How do you set up a straight-in final?
A good straight-in final is established early enough that alignment, speed and configuration are settled before the aircraft reaches the runway environment.
- Confirm the runway and procedure. Check the wind, runway length, surface, traffic, terrain and any published restrictions. At a controlled aerodrome, follow the clearance or vectors; elsewhere, use the prescribed frequency and local joining procedure.
- Place the aircraft on the extended centreline. Verify the runway using its position, lighting, markings and surrounding features. Runway numbers are rounded magnetic designators, so multiplying the number by ten does not always give the exact final course.
- Intercept a sensible glide path. A three-degree path rises about 318 feet per nautical mile, although the familiar planning rule is roughly 300 feet per mile above the threshold. Five miles out therefore suggests about 1,500 feet above threshold elevation, with a small allowance for threshold-crossing height.
- Reduce speed before adding drag. Use the aircraft's approved speeds and configuration sequence. Extend the landing gear and flaps within their limits rather than diving steeply and using full configuration to rescue excessive height.
- Set the descent rate. For a three-degree path, groundspeed multiplied by five gives a useful initial vertical-speed estimate: 90 knots needs about 450 feet per minute, 120 knots about 600, and 140 knots about 700. Adjust for the visual or electronic glide-path indication.
- Hold alignment and aim point. Use coordinated corrections to keep the extended centreline under the aircraft. The intended aiming point should remain nearly stationary in the windscreen; if it moves upwards, the aircraft is trending short, while downward movement indicates an overshoot.
- Make a positive landing decision. Continue only when the runway is identified, traffic is clear and the aircraft is stable. Otherwise, apply the published or normal go-around procedure without trying to salvage the approach close to the ground.
How far out should you join a straight-in approach?
Join far enough out to become stable, but not so far away that you obstruct or confuse established circuit traffic.
A light aircraft may need only several miles of final, while a fast jet requires more distance for deceleration and configuration. Work backwards from the aircraft's stabilisation point, accounting for groundspeed, flap and gear limits, descent geometry and any ATC instructions. There is no universal distance suitable for every aircraft or aerodrome.
When using a PAPI or VASI, make small corrections towards the normal indication. Do not dive aggressively from well above the lights; remaining high, repositioning or going around is safer than forcing a steep, unstable descent.
When is a straight-in approach stable?
The approach is stable when the aircraft is on the correct flight path, at the planned speed, in landing configuration and requiring only small corrections.
- The correct runway and final course are positively identified.
- Landing gear, flaps and checklists are complete at the planned point.
- Airspeed is near the aircraft's target, including any approved wind additive.
- Power and descent rate are appropriate rather than rapidly changing.
- The aircraft can land in the intended touchdown area without excessive manoeuvring.
- Runway clearance, traffic separation and required visual references are assured.
Many operators use stabilisation gates around 1,000 feet above the aerodrome in instrument conditions and 500 feet in visual conditions, but these are not universal rules. Use the aircraft manual, operator policy and local regulations that apply to the flight.
Should you fly straight in at a non-towered aerodrome?
A straight-in arrival is appropriate only when local rules permit it and it can be integrated without disrupting aircraft already in the circuit.
Listen before joining, report your position as required and build a clear picture of other traffic. A long final does not automatically give priority, and another pilot may be unable to see an aircraft approaching head-on against the background. If spacing is doubtful, break off early and fly the published circuit; our traffic-pattern guide explains the normal joining, spacing and final-turn sequence.
Procedures differ between countries and individual aerodromes. Some locations discourage or restrict straight-in joins, so consult the applicable chart and published operating information rather than relying on a generic circuit habit.
Common straight-in approach mistakes
- Arriving high and fast: extend the final, reduce speed earlier or go around instead of forcing the aircraft down.
- Joining without checking traffic: monitor the frequency and visually scan the circuit before committing to final.
- Selecting the wrong runway: cross-check the runway designation, orientation, approach lights and navigation indications, especially where parallel runways exist.
- Chasing the glide path: make measured power and pitch changes, then allow time to see their effect.
- Configuring too late: plan gear, flap and checklist points before reaching the stabilisation gate.
- Continuing an unstable approach: a go-around is the correct response to excessive speed, sink, misalignment, occupied runway or lost visual reference.
