機場(chǎng)中的長(cháng)五邊，短五邊是什么意思

長(cháng)五邊：當航空器在距接地點(diǎn)7公里（4海里）以上轉向第五邊時(shí)，或當直線(xiàn)進(jìn)近的航空器距接地點(diǎn)15公里（8海里）時(shí)，報告“l(fā)ong final （長(cháng)五邊）”

短五邊：根據ICAO文件，以此推理，“short final”就是指航空器在距接地點(diǎn)小于7公里（4海里）時(shí)做的報告。

擴展資料：

五邊分別為：

一邊（離場(chǎng)邊）

二邊（側風(fēng)邊）

三邊（下風(fēng)邊）

四邊（基線(xiàn)邊）

五邊（最后進(jìn)近）

五邊飛行步驟：

假設由09跑道（航向090）起飛，飛行高度為 1000尺。

1、起飛后，機師就會(huì )進(jìn)入 Upwind （離場(chǎng)邊）。

2、維持航向，當爬升至500尺，左轉90度，進(jìn)入 Crosswind （側風(fēng)邊）。

3、維持航向，繼續爬升至1000尺。到達1000尺時(shí)，向左轉90 度，進(jìn)入 Downwind （下風(fēng)邊）。

4、維持航向及高度（1000尺），航向為 270 并和跑道成一條平行線(xiàn)，反方向于離場(chǎng)跑道。此時(shí)，機師需要進(jìn)行降落檢查，并向航管員表示進(jìn)入 Downwind，要求飛行意向（在此為降落）。經(jīng)航管員指示后，機師可以開(kāi)始減速左轉90度并開(kāi)始下降，進(jìn)入Base （底線(xiàn)）。

5、進(jìn)入下降階段，航向為 180，調至進(jìn)場(chǎng)速度，再左轉 90 度，就進(jìn)入 Final （最后進(jìn)場(chǎng)邊）。

6、機師已經(jīng)可以見(jiàn)到跑道在正前方，準備降陸。

機場(chǎng)中的長(cháng)五邊，短五邊是什么意思

五邊飛行是飛行員一課重要的訓練,其主要是圍著(zhù)機場(chǎng)進(jìn)行,從五邊飛行中,機師可以練習到起飛,爬升,爬升轉向,定向,保持高度平飛,下降,下降轉向,降落。所以初學(xué)機師很適合進(jìn)行五邊飛行的練習,從而提高自己對飛機的控制。

一般我們會(huì )用小型機來(lái)作這個(gè)練習,如 cesana 172, 152......, 因為比較易於控制,速度亦不會(huì )太快,以下將會(huì )解釋五邊飛行要注意的地方:

學(xué)習五邊飛行一般五邊飛為一個(gè)長(cháng)方型環(huán)繞著(zhù)機場(chǎng)的航線(xiàn),我們多數會(huì )在起飛後向左轉,爬升及保持在1000ft (AGL) （1000 ft AAL, Above Aerodrome Level)

假設我們在36跑道起飛,機場(chǎng)正向著(zhù)360度,起飛後我們便會(huì )進(jìn)入

"Upwind(離場(chǎng)邊)":當飛行員起飛後立即會(huì )進(jìn)入

"Upwind(離場(chǎng)邊)",然後保持跑道航向360爬升至500ft (AGL),左轉90度,接著(zhù)進(jìn)入;

"Crosswind(側風(fēng)邊)":繼續爬升并在航向090,到達1000ft(AGL)向左轉90進(jìn)入;

"Downwind(下風(fēng)邊)":在此時(shí)你應該在1000ft (AGL)并保持高度(正負50ft),航向為180并和跑道成一條平行線(xiàn),反方向於離場(chǎng)跑道。在這開(kāi)始降落檢查,告知航管員你正在 Downwind并表示你的意向(如.Request full stop landing要求降落)。開(kāi)始減速左轉90度并開(kāi)始下降,然後進(jìn)入;

"Base(底線(xiàn))":這時(shí)已在下降階段,航向270,進(jìn)場(chǎng)速度,再左轉90度,便進(jìn)入:

"Final(最後進(jìn)場(chǎng)邊)":此時(shí)你應該很接近跑道,并準備來(lái)一個(gè)安全的著(zhù)陸。

重點(diǎn): 要注意進(jìn)行五邊飛行時(shí)龍和機場(chǎng)保持較接近的距離(大約在 2海浬內),因為在這個(gè)范圍如遇上機件問(wèn)題,你亦可以進(jìn)行滑翔回機場(chǎng)盡量控制高度於正負50ft內,這樣可以提高你對高度的控制技術(shù)可能進(jìn)行一些Touch And Go的練習(著(zhù)陸後立即再起飛),但要留意請先向航管員申請

以下將解述在不同的方法進(jìn)入機場(chǎng)航線(xiàn)的方法,我們簡(jiǎn)分為6個(gè)不同的方向:

航機1: 繼在 10000ft (AGL)的高度并進(jìn)入Crosswind(側風(fēng)邊),跟著(zhù)進(jìn)行五邊飛行再和航管聯(lián)絡(luò )告知意向。

航機2: 繼在 10000ft (AGL)的高度并進(jìn)入Crosswind(側風(fēng)邊),跟著(zhù)進(jìn)行五邊飛行再和航管聯(lián)絡(luò )告知意向。

航機3: 繼在 10000ft (AGL)的高度并進(jìn)入Crosswind(側風(fēng)邊),跟著(zhù)進(jìn)行五邊飛行再和航管聯(lián)絡(luò )告知意向或如果機場(chǎng)繁忙時(shí)在1500ft (AGL)或航管員所給的高度越機場(chǎng)上空進(jìn)入Upwind(離場(chǎng)邊),再下降到1000FT (AGL)進(jìn)入Crosswind(側風(fēng)邊)。

航機4: 約在 1000ft (AGL)的高度并進(jìn)入Downwind(下風(fēng)邊),跟著(zhù)進(jìn)行五邊飛行再和航管聯(lián)絡(luò )告知意向。

航機5: 進(jìn)入Base(底線(xiàn)),跟薯和航管聯(lián)絡(luò )告知意向并準備下降及著(zhù)陸。

航機6: 進(jìn)行直接進(jìn)場(chǎng)(Straight In Fianl)或如果機場(chǎng)繁忙時(shí)在1500ft (AGL)或航管員所給的高度飛越機場(chǎng)上空進(jìn)入Upwind(離場(chǎng)邊),再下降到1000FT(AGL)進(jìn)入Crosswind(側風(fēng)邊)。

重點(diǎn): 以上是一般目視飛行時(shí)采用的進(jìn)入機場(chǎng)航線(xiàn)方法,實(shí)際進(jìn)場(chǎng)須要以航管員的指令為準。

學(xué)院學(xué)習的時(shí)候我記得小于4NM是短五邊,距離10NM的點(diǎn)是長(cháng)五邊點(diǎn).機組有時(shí)要求直飛長(cháng)五邊點(diǎn),就是這個(gè)點(diǎn).長(cháng)五邊我個(gè)人理解，只要是它和正常起落航線(xiàn)五邊長(cháng)度的比較,比它長(cháng)的就是長(cháng)五邊,比它短的就是短五邊.有沒(méi)有飛行的朋友,發(fā)表一下意見(jiàn)吧!

弄清五邊的概念前，先說(shuō)明一下起落航線(xiàn)的五邊，起飛后，沿跑道方向上升不低于100米，夜間為150米，此時(shí)為一邊，到達此高度時(shí)可以進(jìn)行一轉彎，轉彎角度為90度，到達二邊，依次類(lèi)推，第四次轉彎后，到達的就是5邊，此時(shí)的方向應該與一邊的航向是相同的。長(cháng)五邊是相對正常的起落航線(xiàn)而言的，因為每個(gè)型號的飛機的起落航線(xiàn)數據是相同的，那么五邊的長(cháng)度一致是相等的。長(cháng)五邊的意思就是比正常的起落航線(xiàn)的五邊長(cháng)，使長(cháng)五邊，需要滿(mǎn)足一定的條件，才可以使用長(cháng)五邊落地。短五邊一般好象不提這事，五邊過(guò)短，動(dòng)作多而緊湊，對安全不利。在實(shí)際工作中，我是不用短五邊的。

長(cháng)五邊一般為繁忙機場(chǎng)設計，為了在最后航段安排更多的飛機，一般的支線(xiàn)機場(chǎng)根據地形等情況限制設計較為合適的五邊長(cháng)度，如無(wú)限制因素10NM的五邊長(cháng)度較優(yōu)。

如果飛行員技術(shù)過(guò)硬，運用短五邊目視進(jìn)近可以縮短飛行距離，節省燃油，縮短對五邊的占用時(shí)間，減小對其后邊進(jìn)近飛機的影響，從而提高空域的使用效率。
